In 2012, Rollins Pass was listed as one of the most endangered sites in Colorado.

Naming

''Rollins Pass'' is the sole, official name recognized by both the United States Geological Survey and the United States Board on Geographic Names (BGN); a decision card was issued on Wednesday, December 7, 1904. The pass was first known as ''Boulder Pass''—one of two variant names accepted by the BGN—the other being ''Rogers Pass''. The pass was also known infrequently as Rollinsville Pass. In Grand County, Rollins Pass is sometimes given the sobriquet of ''Corona Pass'', named for the apex station at the summit, Corona. This nomenclature dispute provoked the ire of former railroaders; in fact, Frederick Bauer remarked, " ollins Pass isincorrectly called Corona Pass by neophytes and some locals." It is inconsistent, as well as atypical, to refer to mountain passes by the names of their apex stations. Fremont Pass, for example, is not named ''Climax Pass''; nor is

Description

Rollins Pass has been in continuous use for millennia: first as a sprawling and internationally significant game drive complex that was hand-constructed and used by Paleoindians more than 10,000 years ago through the mid-19th century; followed by nearly two decades as a wagon road from 1862–1880; as a rail route (under survey, construction, and later operational) from 1880 to 1928; as a primitive automobile road from 1936 to 1956; and since September 1, 1956 as a seasonal, unpaved motor vehicle road. The pass is traversed by Paleoindians and Native American game drive complexes, hiking trails, including the Continental Divide Trail; an airway radial (V8), a 10" Xcel Energy high-pressure natural gas pipeline, and two roads: * The first dirt road is the ''Rollinsville and Middle Park Wagon Road'', created in the early 1860s and this route predates the rail line. This road employed much of what would later become Rollins Pass, particularly above timberline. This original wagon route, now called the ''Boulder Wagon Road'', took a steep counterclockwise route up Guinn Mountain encircling Yankee Doodle Lake before continuing to head west/northwest to proceed over the summit and down into the Middle Park valley near present-day Winter Park and Fraser, Colorado. * The second dirt road is mostly the former roadbed of the Denver, Northwestern, and Pacific Railway, that later became the

This high-altitude railroad grade was part of the Moffat Road and this route was replaced (and later abandoned) by the opening of the Moffat Tunnel in 1928; the rails and ties were removed from Rollins Pass in 1936; however, some rail segments as well as ties, made of pine, oak, and walnut, can still be seen, along with planking used for snowsheds.Griswold, P.R.

Geology

The Front Range was created by the Laramide Orogeny, the last of three major mountain-building events, which occurred between 70 and 40 million years ago. Tectonic activity during the Cenozoic Era changed the Ancestral Rocky Mountains via block uplift, eventually forming the Rocky Mountains as they exist today. The geologic make-up of Rollins Pass and the surrounding areas were also affected by deformation and erosion during the Cenozoic Era. Many sedimentary rocks from the Paleozoic and Mesozoic eras exist in the

History

Rollins Pass as a prehistoric Paleoindian & Native American hunting complex

Paleoindians and early Native Americans were the first to utilize Rollins Pass as a natural, low crossing over the Continental Divide for the purposes of communal hunting of large game, including bighorn sheep and

. There are more than 96 documented game drives, including the Olson game drive, found largely above timberline and near the summits of multiple mountain ridges. Handmade rock walls drove prey toward hunters waiting in blinds. These unique high-altitude constructs were built, refined, and continually used over millennia. The game drives built on—and over—Rollins Pass have international significance.

The Olson game drive

The Olson site (5BL147) is a multi-component rock walled game drive and is but one part of a much larger game drive complex located on Rollins Pass. Byron Olson and James Benedict conducted work at the site in the late-1960s. Present-day archaeology teams built on Olson and Benedict's work to expand the overview of the site using modern techniques. As of 2013, at least 45 blinds as well as 1,307 meters of rock walls are present across the Olson site; the purposes of which were to funnel game upslope to waiting hunters. Both radiocarbon and lichenometric dating suggest occupation by Native Americans spanning the last 3,200 years, with diagnostic tools suggesting even older use of the site, dating back to more than 10,000 years ago.

Other significant game drives

Game drives at other locations on Rollins Pass yield hundreds of additional blinds and miles of rock walls.

Rollins Pass as a late-prehistoric and historic Native American route

Rollins Pass has a documented history as a migratory route, hunting trail, and battlefield among the late prehistoric and contact-period Indians of Colorado.

Rollins Pass as an historic wagon road

The first recorded use of the pass (then known as ''Boulder Pass'' or ''Rollinsville Pass'') by a wagon train was in 1862, nearly 14 years before Colorado became a state. Directions for wagons traveling from Rollinsville to Winter Park were published in newspapers. John Quincy Adams Rollins, a Colorado

pioneer Pioneer commonly refers to a settler who migrates to previously uninhabited or sparsely inhabited land. In the United States pioneer commonly refers to an American pioneer, a person in American history who migrated west to join in settling and dev ...

from a family of pioneers, constructed a toll wagon road over the pass in the 1873, providing a route between the Colorado Front Range and Middle Park; subsequently, Rollins Pass was named after John Q.A. Rollins.

John Quincy Adams Rollins

John Q.A. Rollins was born on Sunday, June 16, 1816 in Gilmanton, New Hampshire and was the son of a New England minister. Rollins is described as being a strong man and an extensive character, popular with almost everybody whom he did not owe and his one predominating fault was his failure to pay his debts. Newspapers cited that he was so careless about his credit that he could not keep track of all his creditors, and in turn, they had trouble keeping track of him. Rollins died on Wednesday, June 20, 1894 and is buried in Colorado's oldest operating cemetery,

mentions, "No man in Northern Colorado was better known nor counted more warm friends than John Q.A. Rollins."

Middle Park and South Boulder Wagon Road Company

John Rollins capitalized on this and received approval for his toll wagon road on Tuesday, February 6, 1866. The Council and House of Representatives of Colorado Territory passed an act signed by the governor approving the wagon road as the "Middle Park and South Boulder Wagon Road Company." Records reflect the incorporators as "John Q.A. Rollins, Perley Dodge, Frederic C. Weir." Yet, the "Rollins road" through Boulder Pass was not completed until the first half of August 1873. While the newspaper articles cited "wagons can now be taken over this route without the slightest trouble," other articles countered, "the trail ... is splendid for horses but fearful for wagons" and "the rocks, mud-holes, bogs, creeks, boulders and sidling ledges of that road, can only be appreciated by being seen, the only wonder is that a wagon can be taken over at all." Other articles were a bit more grim, referring to the wagon road as a "little more than the rocky ridge of a precipice along which lurked death and disaster." Newspaper records reflect on Friday, June 12, 1874, James Harvey Crawford along with his wife, Margaret Emerine Bourn Crawford, made pioneer history as the first (nonindigenous) couple to cross Rollins Pass by wagons, and Mrs. Crawford is credited as the first woman to cross the pass. That day held many challenges, including a two-hour blizzard, "which was of terrific violence" and she remarked in a newspaper article, "the bumping was so hard I thought I was nearly dead." As there was no formal road constructed from "Yankee Doodle Camp on up, only an Indian trail, she and the children had been left behind while her husband took the wagon pulled by a pair of mules, a team of horses and a yoke of oxen on up and camped. Then he came back for her with the team and the running gear only of the wagon, and she had to hold the children on someway, despite the dreadful bumping" with the "wagon almost standing on end." The pass was used heavily in the latter half of the 19th century by settlers and at one time as many as 12,000 cattle at a time were driven over the pass. The wagon road had one tollgate and the following rate structure: "For each vehicle drawn by two animals, two dollars and fifty cents; for each additional two animals, twenty-five cents; each vehicle drawn by one animal, one dollar and fifty cents; horse and rider and pack animals, twenty-five cents; loose stock, five cents per head ... horse with rider, or pack animal with pack, ten cents." The cost for nonpayment of a toll was the same as causing intentional damage to the road: $25. According to the manuscript of Martin Parsons, "Twistin Dogies Tails Over ''Rollins Pass''", each summer, Mr. Rollins would "build a cribbing of logs ... and would fill the center with rocks and earth, which helped reduce the grade between the hills." The original log cribbing can be seen today on the narrow ridge of Guinn Mountain, north of Yankee Doodle Lake. Rollins also built ''The Junction House'', "a large, two-story hewd-log structure" as a hotel, "at the point of intersection of the Berthoud and Rollins roads." The road began to fall out of use and into disrepair in 1880, approximately one year before early railroading attempts over the pass begun.

Mining efforts on Guinn Mountain at Yankee Doodle Lake

Guinn Mountain, encircling Yankee Doodle Lake, was used for mining from the early 1870s through the establishment of the railroad in 1904. This area held at least "four silver lodes" or "five patented lode claims, one patented placer claim, several prospect pits and the dump of one caved adit." This caved adit, once , then lengthened to , is still shown as a mine on United States Geological Survey topographic maps as the ''Blue Stones Mine''. This tunnel exposed a "five-foot vein of ore varying in values from $16 to $25 per ton." It was concluded that the "Guinn Mountain area has little or no economic potential," despite listings of important mineral strikes in period newspapers. Further, "ten samples collected in the area contained only negligible amounts of any metal. Samples from the Avalon placer claim, located on the South Fork fMiddle Boulder Creek north of Guinn Mountain, and from the creek bottom were collected and panned; no gold was found." Despite this record, gold claims were nevertheless worked nearby with no published record of success.

Early railroad endeavors

There were multiple prior efforts to build a railroad over Rollins Pass in the 19th century and all attempts were met with impassable engineering challenges, financing issues, or both: ''GHS, Jefferson, & Boulder County Railroad and Wagon Road'' (A.N. Rogers' line) in 1867; ''U.P.'' in 1866; ''Kansas Pacific'' in 1869; ''Colorado Railroad'' (B. & M. subsidiary) in 1884—two tunnels located; '' Denver, Utah & Pacific'' in 1881 (construction started and tunnel located). The remains of the latter tunneling attempt can still be seen on the northern slope of the rock wall at Yankee Doodle Lake and the detritus from the attempted excavation of the tunnel was placed at the northernmost part of the lake where pulverized granite tailings can be seen rising out of the water. These tailings were definitively from the 1880s tunneling efforts as they are not visible in the early

McGraw-Hill Publishing Company. April 22, 2019 – via Google Books. However, the railway only reached Craig, Colorado. This entire line from Denver to Craig was known as the Moffat Road. The line included a stretch over the top of the Continental Divide, at Rollins Pass, with a two to four percent grade and switchbacks along many sections; the result was one of the highest adhesion (non-cog) standard-gauge railroads ever constructed in North America. This corridor over Rollins Pass was always intended to be temporary until what would later become the Moffat Tunnel was constructed and opened; therefore this overmountain route was constructed with more cost-effective materials: using wooden trestles (made of all Oregon fir) instead of iron bridges or high fills and wyes instead of turntables. Construction of this route was exceptionally dangerous and deadly: in a single day, 60 Swedish workers were killed when a powder charge exploded prematurely during the construction of ''Needle's Eye Tunnel''. Along this route were three tunnels: Tunnel #31 (''the tunnel at Ladora''), Tunnel #32 (''Needle's Eye Tunnel''), and Tunnel #33 (''the Loop Tunnel at Riflesight Notch''). All three tunnels today are either completely caved in or have had multiple partial cave-ins. Other notable landmarks on the route included the ''Riflesight Notch'' Loop, located at Spruce Mountain: a spiral or loop where trains crossed over a trestle, made a ~90 degree gradual turn to descend , and passed through Tunnel #33 underneath the trestle.Bollinger, E.

Delays affected the timeliness of both newspaper and postal mail deliveries. Coal smoke and toxic gasses collected in the snowsheds causing temporary blindness, loss of consciousness, and sometimes death. Workers on the Moffat Road had an adage: "There's winter and then there's August", reflecting the fact that in the high mountains of Colorado, snow will often cover the area for more than six months and very cold and snowy weather may occur nearly year-round. It was these heavy snowstorms that led to the financial demise of the Moffat Road and served as the incentive for construction of a permanent railroad tunnel through the Rocky Mountains and into Middle Park.

The Moffat Tunnel

Several locations for the Moffat Tunnel were scouted prior to the selection of the present-day location; one possible location was identified at high altitude between Yankee Doodle Lake and the Forest Lakes. Plans to build a longer tunnel at a lower elevation were better planned and financed; the single-track Moffat Tunnel opened just south of Rollins Pass on Sunday, February 26, 1928. The Moffat Tunnel eliminated 10,800 degrees of curvature along the Rollins Pass route; the tunnel resulted in considerable time savings as well as money that was used for snow removal atop Rollins Pass. After the first year of operations, an annual report to stockholders showed "marked savings in operating costs" by 24.86%. Savings were seen in other areas, including in fuel reductions ($89,074.45 savings; $1.3 million in 2018 when adjusted for inflation), engine servicing ($156,188.89 savings); whereas gross tons per train hour increased by 34.84%. After the Moffat Tunnel opened, the tracks over Rollins Pass remained in place and were maintained at least as late as July 1929 as an emergency route. This emergency route was needed only once for a several day-long closure: on Thursday, July 25, 1929, dry rot of wooden timbers caused a collapse and of rock caved-in and blocked the Moffat Tunnel near the East Portal. It took until Tuesday, July 30, 1929 for the tunnel to be cleared of debris. Permission to dismantle the rails on Rollins Pass was granted by the

A wye on the passing siding at the East Portal of the Moffat Tunnel is currently utilized for short-turning some modern services and marks the spot where the Rollins Pass line, if it still existed, would have merged into the modern route.

The original 1922 law that authorized the construction of the Moffat Tunnel specified that it should also be used for automobile traffic, with automobiles being placed on a ferry of flatbed railcars.

Rollins Pass as an air route and navigational waypoint

In the era of powered flight, Rollins Pass provides an attractive way to cross the Continental Divide between west and east at a relatively low point for aircraft. Not only does the enroute airway radial, ''Victor Eight'', cross the pass; but also a rotating airway beacon was established in the mid-to-late 1940s and first appeared on aeronautical sectional charts in March 1948 as a star, indicating a beacon.

Each summer, from 1956–1979, Rollins Pass served as a complete road over the mountain pass for automobiles until a substantial rock fall in ''Needle's Eye Tunnel'' in 1979 closed the path over the pass. In 1989, after several engineering studies and structural strengthening of ''Needle's Eye Tunnel'' were accomplished, the complete road was re-opened only to close permanently in 1990, due to a rockfall injuring a sightseer. For the past years—since July 1990—no motorized route connects across the Continental Divide, effectively making each side a dead-end uphill route that must be traveled again, downhill, to leave the pass.

Rollins Pass as a natural gas pipeline route

In 1969, a natural gas pipeline was placed on Rollins Pass. In the mid-1990s, Rollins Pass was closed for the installation of a diameter Xcel Energy high-pressure natural gas pipeline. The pipeline, not always under marker, still is in existence and uses the low pass to reach the Front Range by loosely following County Road 8 in Fraser, utilizing much of Ranch Creek towards the Middle Fork of Ranch Creek below Mount Epworth, climbing the pass near Ptarmigan Point, and following much of the old railbed past Corona at the summit of Rollins Pass. The pipeline continues across the railbed towards and under the twin trestles, down the old wagon route on the spine of Guinn Mountain, and then towards Eldora. The pipeline undergoes internal inspections "at least" every seven years with the deployment of a

The material record of Rollins Pass is illegally carried away each year—some by poachers—others in the backpacks of well-intentioned visitors who want a souvenir; but once artifacts are removed, a place can never again reveal the mysteries of the past. Each artifact has important scientific and cultural value and theft harms the historical record. Visitors are encouraged to preserve the area for future generations by leaving items in place and sharing photographs and GPS coordinates (if available) with researchers dedicated to telling the story of Rollins Pass and an internet resource has been setup to aid with this project.

Artifacts affecting the road prism

On both sides of Rollins Pass, the road prism contains both prehistoric and historic artifacts buried under the surface. Any improvements to the rough road through regrading, including paving, would first require extensive sectional archaeological excavations by the United States Forest Service. In several places, on or just under the surface, historical artifacts are covered with geotextile stabilization fabrics having characteristics that match the soil and permeability of the existing roadbed.

Drystacks

There are several drystack retaining walls on both sides of the pass, built without mortar, helping ensure they retain soil but not water.

Ghost towns, settlements, and gravesites

There are several ghost towns on or near Rollins Pass, the most notable being Arrow, Corona, Ladora, the East Portal construction camp, Mammoth, and Tolland. There are also at least a half-dozen other established settlements, dating back to both the wagon road and railroad eras, scattered across Rollins Pass. There are also several historic gravesites across Rollins Pass. One granite headstone at Arrow reads, "R.M. Smith , June 28, 1842 , Nov. 12, 1909."

. The latter being extremely fragile and if damaged, can take 100–500 years to recover. Leaving the trail can cause erosion, land degradation, possible species extinction, and habitat destruction and it is for these reasons vehicles, including off-road vehicles, are not allowed to leave the established road. There are at least two marked revegetation areas on Rollins Pass: one at Yankee Doodle Lake; the other at the summit leading to the historic dining hall foundation.

Pine beetle epidemic

The mountain pine beetle epidemic, beginning in 1996 and continuing through present day, affects many forested areas in Colorado, including those on Rollins Pass. One out of every 14 trees in Colorado is dead. Trees affected by the beetles contain 10 times less water than a healthy tree and crown fires can quickly spread.

Fauna

The top predator in the area are black bears (''Ursus americanus''), generally below timberline; however, they occasionally venture above the krummholz. The bears prey on bighorn sheep (''Ovis canadensis'') and mountain goats (''Oreamnos americanus''), as well as

yellow-bellied marmot The yellow-bellied marmot (''Marmota flaviventris''), also known as the rock chuck, is a large, stout-bodied ground squirrel in the marmot genus. It is one of fourteen species of marmots, and is native to mountainous regions of southwestern Canad ...

Riparian zones

Nutrient-rich ecosystems exist on Rollins Pass where water, and bodies of water, meet the alpine and subalpine tundras.

Lakes

There are three lakes on the west side of Rollins Pass: ''Deadman's Lake'', ''Pumphouse Lake'', and ''Corona Lake''. On the east side of Rollins Pass are ''King Lake'', ''Yankee Doodle Lake'', and ''Jenny Lake''. Historically, Yankee Doodle Lake was referred to as ''Lake Jennie'' by John Quincy Adams Rollins, but modern archaeologists have re-interpreted this to be the modern day Yankee Doodle Lake; the railroad and period newspapers occasionally referred to this lake as ''Dixie Lake''. Also in the vicinity: ''Bob Lake'', ''Betty Lake'', the ''Forest Lakes'', ''Skyscraper Reservoir'', ''Lost Lake'', and ''Woodland Lake''. In 2010, Pumphouse Lake and Ranch Creek were assessed by the

Creeks and rivers

On the west side, in addition to the Fraser River at the start of Rollins Pass are the following creeks: the South Fork of Ranch Creek, the Middle Fork of Ranch Creek (fed by Deadman's Lake), and Ranch Creek (fed by Pumphouse and Corona Lakes). On the east side of Rollins Pass, the South Fork of the Middle Boulder Creek is fed by Bob and Betty Lakes and Jenny Creek is fed by both Jenny and Yankee Doodle Lakes; further downstream, Antelope Creek feeds into Jenny Creek. The South Boulder Creek runs at the start of Rollins Pass on the eastern side; but first flows through ''Buttermilk Falls'', a large waterfall, near King Lake, visible from the summit and upper eastern portions of Rollins Pass.

Improvements

A summer 2006 project led by the United States Forest Service and having the participation of both environmental and user groups saw improvements made to wetlands, lakeshore, and upland habitats at Yankee Doodle Lake and Jenny Creek. Fencing was installed to restrict vehicle travel to designated routes and improve degraded areas. Before work could begin, sectional excavations by archaeologists took place to document the wagon road era settlements of the "Town of Yankee Doodle at Lake Jennie," located at present day Yankee Doodle Lake.

Wildfires

In the summers, wildfire danger increases due to various environmental factors: low moisture, lightning strikes, high winds, and human-caused factors. As the pass is a recreational area, wildfires can also be caused by unmanaged, unattended, and/or uncontrolled campfires.

Fire restrictions

At present, fire restrictions apply to the areas comprising Rollins Pass. Typically, these protective restrictions tend to be enacted starting as early as mid-late July or later in August: * On Friday, July 10, 2020, the east side of Rollins Pass, located in both Boulder and Gilpin counties, went under Stage 2 Fire Restrictions. * On Friday, July 10, 2020, the west side of Rollins Pass, located in Grand County, went under Stage 1 Fire Restrictions on USFS lands only.

Nature caused

* On Saturday, August 3, 1996, a lightning strike caused one of the easternmost wooden trestles near the summit to catch fire; the blaze was extinguished by fire crews before the trestle's integrity could be compromised. The wooden trestle was likely saved by the use of coal-tar creosote applied to treat and preserve the wood, as part of the Bethell process.

Human or equipment caused

* On September 27, 1915, Mart Wolf, owner of the Elk Creek Saloon, set fire to his establishment in the town of Arrow on the west side of Rollins Pass in the hopes of collecting insurance money totaling $1,000. Due to high winds, the fire quickly spread and Arrow was all but snuffed out of existence. * On Wednesday, October 30, 1918, a fire started at or near the boiler house (on the south side of the Corona shed) and fanned by winds claimed the power station, telegraph system at the summit,"Steamboat Pilot October 30, 1918 — Colorado Historic Newspapers Collection"
''Coloradohistoricnewspapers.org''. along with several miles of track, snowsheds, as well as buildings at Corona, including the destruction of the water tank upon which the Weather Bureau's observation station was mounted. Train service over the pass, after the rails were relaid, resumed on Friday, November 1, 1918; snowshed reconstruction caused delays, yet continued through November and December. A new electric lighting system was installed at the summit the next year (1919)."Routt County Sentinel November 29, 1918 — Colorado Historic Newspapers Collection"
''Coloradohistoricnewspapers.org''. Box cars were used as temporary buildings as the workers' quarters (for watchmen and operators), the depot, telegraph office, eating house (not to be confused with the dining hall), and more were destroyed. * In 1923, a train caused a wildfire on the east side of Rollins Pass on Giant's Ladder. * On Thursday, October 15, 1925, passenger train No. 2, including caboose, was completely destroyed by a fire in the Corona snowshed; the fire consumed roughly of snowshed. * On Wednesday, January 26, 1927, the town of Rollinsville was nearly destroyed by a fire believed to have been started by a spark from a locomotive. Five buildings were destroyed and 20 guests in the Rollinsville hotel lost their personal belongings when the hotel burned to the ground. * On Friday, August 19, 1938, a manmade fire started and was spread by high winds near the East Portal of the Moffat Tunnel. More than 700 men helped to fight the fire that consumed at least 800 acres near Tolland. * On Wednesday, August 4, 2010, a plane crash on the east side of the pass caused a small wildfire.

Unknown cause

* On Tuesday, July 30, 2019, a small sub-acre fire ignited behind the Lakota subdivision on the lower portions of Rollins Pass; the fire was extinguished by the following evening.

Climate

Seasons

Winter

Arctic conditions are prevalent during the winter, with sudden blizzards, high winds, and deep snowpack. High country overnight trips require gear suitable for or below. The subalpine region does not begin to experience spring-like conditions until June. Wildflowers bloom from late June to early August.

Summer

Due to high-elevation above timberline in a backcountry setting, there is neither lightning protection nor lightning mitigation from sudden thunderstorms resulting in a high-risk, extremely dangerous situation for visitors. The most suitable—but not best—refuge available from electrical storms would be in a metal-topped vehicle as it would serve as a mobile

Weather equipment and historical records

Historical

During the railroad era, a United States Weather Bureau observation station was mounted atop the large water tank at the townsite of Corona. Records from this station show "the prevailing wind direction was west, the lowest temperature recorded was (in February 1910), and the most monthly snowfall was in March 1912 with of snow." Newspaper reports mention winds in excess of , including at least one instance of , and temperatures of . Both these temperatures and wind speeds are in line with today's conditions in Colorado's high mountains.

Present day

A small, solar-powered weather station exists on the west side of Rollins Pass, located above Ptarmigan Point.

Atmospheric pressure

While temperature, humidity, and other factors influence atmospheric pressure, the atmospheric pressure on the summit measures roughly ; while a standard atmospheric pressure measured at sea level is . At this pressure, many people, especially out-of-town visitors from lower elevations, can suffer from rapid dehydration and altitude sickness, also known as acute mountain sickness. Acute mountain sickness can progress to high-altitude pulmonary edema (HAPE) or high-altitude cerebral edema (HACE), both of which are potentially fatal. Historically, newspaper reports wrote of both visitors and railroad workers experiencing heart attacks and pneumonia at the summit of Rollins Pass as well as severe frostbite, including in July.

Avalanches

Human-triggered and natural avalanches are possible anywhere on the pass and there have been four notable avalanches—three at Yankee Doodle Lake—on Rollins Pass:

Railroad era

* On Tuesday, January 27, 1914, sliding snow from Tunnel #32 "completely covered the track for a long distance" caused a multi-day blockage at or near Yankee Doodle Lake. * On Monday, December 10, 1917, an avalanche near Yankee Doodle Lake swept a rotary and assisting engine off of the tracks. The engineer of the assisting engine was "scalded about the head so badly that the bones of the face were exposed and he is not expected to live." Other railroad workers died and several were injured.

Post-railroad era

Backcountry skiers, snowshoers, and snowmobilers are advised to check daily avalanche forecasts, practice diligent terrain management, and always carry and know how to use rescue gear, including Emergency Position-Indicating Radio Beacons (EPIRBs). • On Wednesday, November 28, 2001, two highly-experienced backcountry skiers triggered a sizable hard-slab avalanche in the Yankee Doodle Lake basin. From the accident report, "The avalanche released from a southeast-facing slope and fell and stopped by crashing through the thick ice of Yankee Doodle Lake. The displaced water resulted in a surge tall along the south shore." The avalanche pushed both men into the lake and one survivor was sent into the center of the lake. The survivor, suffering from hypothermia and frostbite, hiked o to the

, and trained dive-rescuers with specialized rubber suits. The body of the second skier was found offshore. Both skiers were well-equipped, including having avalanche transceivers. Following the accident, each year in December, the Rocky Mountain Rescue Group holds a ''Joe Despres Memorial Dry Land Transceiver Training'' to include practices for using transceivers, along with avalanche courses, fundraising, and backcountry seminars. • On Sunday, February 14, 2021, a 58-year old male triggered an avalanche on the east-facing slope of Mount Epworth while snowmobiling and perished at Pumphouse Lake. • On Saturday, January 7, 2023, two snowmobilers triggered a fatal avalanche on the eastern slope of Mount Epworth. One snowmobiler, age 58, was wearing an avalanche beacon—his body was recovered the same day; the other man, age 52, was not wearing an avalanche beacon and the recovery operation was postponed until the following day. The recovery operating involved the Grand County Sheriff’s Office, Grand County Search and Rescue, Grand County EMS - Mountain Medical Response Team, Winter Park Ski Patrol Dog Team, Flight For Life Colorado, and the Colorado Avalanche Information Center (CAIC).

Access

General information and seasonal recreation

Rollins Pass is managed by the United States Forest Service as a recreational location and can be accessed from roads on both west and east sides; however, no motorized route connects across the Continental Divide. The entire road is unpaved (dirt and rock), has no guardrails, and has a speed limit of . Current-year Motor Vehicle Use Maps (MVUMs) should be reviewed to determine which trails and roads are open to vehicles. Violators are subject to fines up to $5,000—"regardless of the presence or absence of signs" and operating a vehicle in wilderness areas is prohibited. Buck and rail fences have been placed at select areas on the pass to indicate routes or areas closed to motor vehicles. There are no facilities, shops, restrooms,

es, water fountains, trash receptacles, nor shelters located on either side of the pass. The only exception is the Årestua Hut, located on the northern side of Guinn Mountain at on the east side of Rollins Pass. The small hut was constructed years ago and is open year-round. A series of hand-constructed stone windbreaks exist above timberline north of ''Needle's Eye Tunnel''—these structures date to the railroad era on Rollins Pass and are not prehistoric. These windbreaks currently lack upper coverings or roofs and serve only as aerodynamic dampeners for wind and wind gusts.

Winter

Both sides of the pass can be traveled by snowmobile when at least of snow cover the road in the winter—generally beginning in late November or early December and lasting through early April.

Spring

Both sides of the pass are ''closed'' in spring—including several weeks in June—to any form of motorized traffic: snowmobiles, automobiles, Off-road vehicles (ORVs), All-terrain vehicles (ATVs), or motorcycles for the prevention of road damage.

Summer and early autumn

. Rollins Pass is scheduled open for vehicular summer traffic from June 15 through November 15; however, it is generally not possible given typical snowfall accumulations and slower melt rates in southerly-shaded areas, to drive higher than Sunnyside (site of the old block station) or Ptarmigan Point on the western side, or Yankee Doodle Lake on the eastern side before early-to-mid July. In 2019, and in other summers when the prior season's snowfall has been late and/or considerable, mid-elevation gates on the west side of Rollins Pass remained closed on June 15 due to an order, "''Extended closure due to snow, runoff, and road damage 36 CFR 261.54a.''"

that are not plowed; this effectively puts higher landmarks—including the summit—out of reach as soon as late September or early October. On average, the near-annual existence of snow at or above timberline, ensures the road is only passable less than 90 days per year. Summer usage of the pass is currently classified as 'heavy' by the United States Forest Service; as such, parking can be very limited at designated parking sites. While the route mostly has gentle grades with switchbacks between two and four percent and does not contain loose gravel, four-wheel drive higher-clearance vehicles fare better than two-wheel drive vehicles, particularly in certain technical sections: some areas on the east side have up to a 17.63% grade; the west side has some areas with a 15% grade. In all narrow sections, the vehicle heading downhill must yield to the vehicle traveling uphill.

From the north or south (along the Continental Divide Trail)

The Continental Divide Trail crosses the summit of Rollins Pass from south to north; the trail bisects the former wye at Corona and takes hikers through the Indian Peaks Wilderness past the dining hall foundation at the summit.

From the east (near Rollinsville & Tolland)

The road up the pass on the eastern side from the Peak to Peak Highway ( State Highway 119) begins at the East Portal road running west, parallel to South Boulder Creek and the current Union Pacific Railroad tracks, to the East Portal of the Moffat Tunnel, and then rises on the abandoned railroad grade from Giant's Ladder to the closed ''Needle's Eye Tunnel''. From Rollinsville to East Portal, the road is an all-weather gravel road, with several chattery washboard sections, that can be traveled by regular automobiles. However, beginning at East Portal, at the formal start of Rollins Pass road (Forest Service Road 117), the road prism becomes very rough due to sustained sections of angular cobbles and potholes, the latter being several feet in size. The road has a level 2 road maintenance status described as "assigned to roads open for use by high-clearance vehicles" that includes the following attributes: "surface smoothness is not a consideration" and is "not suitable for passenger cars." This former railroad bed is open for ; two miles past Jenny Lake, there is a concrete-filled steel road gate with large rocks and Jersey barriers approximately one half-mile before ''Needle's Eye Tunnel''. A rough trail continues around either side of the tunnel for non-motorized transportation; the road is open for hiking and mountain biking beyond the barricaded portal of the tunnel toward the summit. No motorized route connects across the Continental Divide. A majority of the lower portion of the east side of the pass is posted

The road has a level 2 road maintenance status described as "assigned to roads open for use by high-clearance vehicles" that includes the following attributes: "surface smoothness is not a consideration" and is "not suitable for passenger cars." The road is open for and terminates at the summit's parking area. Exactly before reaching the summit, capable vehicles can turn right onto County Road 80 and continue via Forest Service Road 501.1—this rough road rises above and bypasses the summit for another before dead-ending overhead Yankee Doodle Lake at Guinn Mountain. No motorized route connects across the Continental Divide. The entrance to and lower portion of Rollins Pass is owned by the Arapaho and Roosevelt National Forest; after roughly , the land transitions to

Guided tours

* Winter: Guided winter snowmobile tours follow much of the summer road from Arrow and terminate shortly after Sunnyside at Ptarmigan Point (located further uphill and past the ''Riflesight Notch'' trestle). Winter tours "top out at nearly 12,000 feet" but do not go higher than Ptarmigan Point and do not reach the summit at 11,676.79 feet. * Summer: Guided summer off-road (off-pavement) tours are also conducted on the west side of Rollins Pass; however, all tours are conducted on-road using off-road capable vehicles and any off-roading is strictly prohibited.

Incidents and accidents

Due to hairpin turns, steep terrain, and inclement weather, there have been several incidents and accidents, some fatal on or near the Rollins Pass road:

Non-motorized

* On Tuesday, March 19, 1968, a young hiker was rescued near the Riflesight Notch trestle after hiking from East Portal to Winter Park without snowshoes, skis, or adequate clothing. * On Wednesday, July 18, 2012, a woman was injured after losing her footing and sliding down a snowfield where she crashed into rocks at the bottom of the slope. The injured woman was taken via a Flight for Life helicopter to Denver. * On Sunday, February 4, 2018, a backcountry skier fell, sustained multiple injuries—including broken bones, and became unconscious. His friend was able to phone for emergency services but a helicopter could not land due to winds and blowing snow. Rescuers could not arrive until 10 hours later. * On Saturday, August 4, 2018, a backcountry skier fell approximately down Skyscraper Glacier on Rollins Pass, impacted rocks, and became unconscious. Search and rescue services were mobilized and the 23-year-old skier was able to hike back to the summit. * On Saturday, July 18, 2020, a backcountry hiker fell approximately 300 feet down a scree slope on Rollins Pass, near Needle's Eye Tunnel, sustained serious injuries, and was found to be unconscious and unresponsive. Search and rescue services were mobilized and the 57-year-old hiker was airlifted to Denver. * On Monday, September 7, 2020, a 17-year-old backcountry skier fell while backcountry skiing on Skyscraper Glacier and smashed into rocks, resulting in a head laceration. Three flights were made over the course of the seven hour rescue and the rescue involved the following agencies: Boulder County Sheriff’s Office, American Medical Response, Nederland Fire Department, Timberline Fire Department, Rocky Mountain Rescue Group, Grand County Search and Rescue, Flight For Life Colorado, Colorado Army National Guard, and the Colorado Search and Rescue Association. * On Sunday, February 21, 2021, a 47-year-old woman became lost while snowshoeing on Jenny Creek Trail towards Yankee Doodle Lake. Fifteen different search and rescue agencies were involved with her rescue, including: Boulder County Sheriff’s Office, Rocky Mountain Rescue Group, Front Range Rescue Dogs, Boulder Emergency Squad, Eldora Ski Patrol, City of Boulder Water Utilities Department, U.S. Air Force Rescue Coordination Center, American Medical Response, Colorado Search and Rescue, Nederland Fire Protection District, Northern Colorado Med Evac, Flight for Life Colorado, Colorado Division of Fire Prevention and Control, Regional Transportation District and Alpine Rescue Team.

Motorized

* In the winter of 2001–2002, a search and rescue effort to extricate men with 'severe hypothermia' ended with a snowmobile wreck near Corona Lake. The wreck resulted in one man's thigh becoming broken in six places. * On Saturday, August 23, 2003, a car illegally off-roaded on the Riflesight Notch Loop and required towing. The driver was fined $500. * On Saturday, October 8, 2011, a car crashed into the South Boulder Creek off of Rollins Pass road, the driver was pronounced dead at the scene and the passenger was taken to the hospital. * On Monday, February 18, 2013, a snowmobiler on the west side of Rollins Pass, lost control of his machine on a groomed trail and struck a tree where he was pronounced dead by search and rescue services. * On Sunday, August 16, 2015, two girls—ages 11 and 12—were driving ATVs underage, went over a cliff on Rollins Pass road; requiring the services of both an ambulance and a

Railroad line

For visitors in or on motor vehicles wishing to access and retrace the old railroad line, the majority of the railroad route or right-of-way over the pass is open and intact with several exceptions, detailed below, and no motorized route connects over the Continental Divide at Rollins Pass: * Some of the railroad trestles have deteriorated (at ''Riflesight Notch''), have been destroyed (trestle #72.83 on the west side, by the FAA

Per the current Motor Vehicle Use Maps, all extant trestles on the pass are closed to any form of motorized traffic, including motorcycles. * Two railroad tunnels on Rollins Pass are completely caved-in: Tunnel #31 (''the tunnel at Ladora'') and Tunnel #33 (''the Loop Tunnel at Riflesight Notch''). * Closures also include sections leading to Tunnel #32, ''Needle's Eye Tunnel''—a high-altitude railroad tunnel constructed in 1903 and used through 1928. Surveyors looking to establish the automobile route over the pass in 1949 found, and cleared, considerable rockfalls at the northeast portal of the tunnel. The tunnel was open to automobiles, as part of the thoroughfare over the pass, from 1956–1979 for seasonal and inessential purposes. In 1979, the tunnel was closed due to rock falls at the northeast portal; following a

. Since then, the tunnel was sealed by Boulder County officials along with the United States Forest Service and sizable rockfalls continue to occur at the northeast portal, southwest portal, and center of the tunnel from both the crown and shoulder of the structure. In November 1990, the post-accident engineering report, by independent geotechnical consultant Ronald E. Heuer, PhD, cited restoration errors and faulty work: design specifications were not consistently followed, rock bolts were incorrectly spaced, and gravity along with seasonal temperature variations were also listed as factors in the accident.

Administrative provision

In 2002, the James Peak Wilderness and Protection Area Act (Public Law 107-216) was passed by Congress and signed into law by President

George W. Bush George Walker Bush (born July 6, 1946) is an American politician who served as the 43rd president of the United States from 2001 to 2009. A member of the Republican Party, Bush family, and son of the 41st president George H. W. Bush, he ...

. The act amended the Colorado Wilderness Act of 1993 and designated lands within both the Arapaho National Forest and the Roosevelt National Forest as the James Peak Wilderness area and added lands to the

, establishing these lands as federally protected territory. The act contained an administrative provision:

If requested by one or more of the Colorado Counties of Grand, Gilpin, and Boulder, the Secretary shall provide technical assistance and otherwise cooperate with respect to repairing the Rollins Pass road in those counties sufficiently to allow two-wheel-drive vehicles to travel between Colorado State Highway 119 and U.S. Highway 40. If this road is repaired to such extent, the Secretary shall close the motorized roads and trails on Forest Service land indicated on the map entitled 'Rollins Pass Road Reopening: Attendant Road and Trail Closures', dated September 2001.

Historically, both Gilpin and Grand counties have requested to re-open the road; however, Gilpin County has publicly withdrawn their support and opposes re-opening the thoroughfare over the pass, along with Boulder County. To date, only minor repairs (mostly washout repairs) have been made. The difficulties and expenses of making improvements to the road, including coordination of maintenance and re-introduced liabilities—coupled with intractable disputes surrounding the 1990 accident in the tunnel, have become contentious and ongoing issues; however, alternative routes utilizing the Moffat Tunnel have been proposed.

Land exchange

A proposed land exchange in 2020-2021 between the US Forest Service and a private developer was halted by historic preservation professionals and advocacy groups. The proposal would have seen the "literal entrance to the western portion of Rollins Pass ..become an entrance to a private development." The developer sought to trade between 1,536 and 2,261 acres of land for 543 acres held by the US Forest Service. Rollins Pass holds resources in a National Historic District spanning Grand, Boulder, and Gilpin counties and this land exchange would have damaged the historic district as well. Unfortunately, this project had initial support from local leadership and economic influencers—including multimillion dollar resorts—yet none of their letters of support mentioned Rollins Pass nor its cultural and non-renewable historic resources. Instead, community leaders mirrored the developer in writing to the US Forest Service that the 543 acres "are squarely in the development path and are a logical place for future growth to occur." This land exchange was discussed in a 2022 book on Rollins Pass:

In recent years, the historic integrity of Rollins Pass has come under new threat from unsympathetic developers longing to build atop soils rich with history that hold panoramic views. Of late, one attempt at a land exchange with the US Forest Service would have transformed the entrance of the western portion of Rollins Pass into an opening, quite literally, for a private development. Advocates rallied on behalf of public lands, and for now, the area remains in public hands. Embarrassingly, continued pro-development aspirations and the failure to see beyond real estate values only reinforces the area’s inclusion as one of Colorado’s Most Endangered Places.

Drone operations

Drone (UAS) flights are permissible in Class G airspace on/over Rollins Pass provided all flights adhere to the FAA’s regulations for recreational or commercial drone flights. The one major restriction is that drones cannot take off from, land in, or be operated from congressionally designated wilderness areas. Remote pilots and drone enthusiasts should exercise extreme caution as the enroute airway radial brings fast-moving aircraft within the area, including

Rotating airway light beacon (Beacon 82)

A rotating airway light beacon (''Beacon 82'' on aeronautical charts), was placed very near the summit of Rollins Pass atop what was then later termed Beacon Peak, in the mid-to-late 1940s at an approximate elevation of . The glass-domed lighted beacon rotated six times per minute, marking the airway between Los Angeles and Denver, and it held a two-million candlepower electric lamp with a parabolic reflector.

In popular culture

Film, music, and books

* Country music artist, Tracy Byrd, recorded a music video for the 1996 single, ''Big Love'', which featured sights on the west side of Rollins Pass, including: Ptarmigan Point, Mount Epworth, Deadman's Lake, ''Riflesight Notch'' trestle, and more. The album cover pictures the artist himself in front of a scenic backdrop that can be seen at the summit of Rollins Pass, looking northeast; the back of the album features the artist holding his guitar while seated on a rock outcropping near the railroad-era dining hall foundation at the summit. * The Metro-Goldwyn-Mayer 1925 silent film, '' The White Desert'', starring Claire Windsor as Robinette McFarlane and Pat O'Malley as Barry Houston was filmed on Rollins Pass in the winter of 1922 and released to the public on Monday, May 4, 1925. The film features moving pictures of long trains ascending ''Riflesight Notch'' trestle and of rotary snowplows in action between Ptarmigan Point and the summit. The railroad imagery is displayed only at both the beginning and the end of the movie with dramatic scenes (mostly indoor or pseudo-outdoor) and both dialogue intertitles and expository intertitles filling most of the film's runtime. The film is considered to be rare and has historical significance due to the footage of trains and rotaries operating on Rollins Pass. * The 1928 Metro-Goldwyn-Mayer silent drama film, '' The Trail of '98'', was filmed in part on Rollins Pass as well as inside the Moffat Tunnel using specialized lighting. The film was directed by Clarence Brown and starred
