Crestone Needle
Crestone Needle is a high mountain summit of the Crestones in the Sangre de Cristo Range of the Rocky Mountains of North America. The fourteener is located east-southeast ( bearing 108°) of the Town of Crestone in Saguache County, Colorado, United States. The Crestones are a cluster of high summits in the Sangre de Cristo Range, comprising Crestone Peak, Crestone Needle, Kit Carson Peak, Challenger Point, Humboldt Peak, and Columbia Point. They are usually accessed from common trailheads. Climbing While not as high as Crestone Peak, and connected to it by a high, jagged ridge, Crestone Needle is regarded as a worthy climb in its own right. The easiest route is the South Face (or South Couloir), usually accessed via Broken Hand Pass from South Colony Lakes. This is a slightly exposed scramble with a few tricky moves, and is one of the more difficult standard routes among the Colorado fourteeners. However the classic route on the mountain is the Ellingwood Arete, also known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ellingwood Ledges (Crestone Needle)
The Ellingwood Arete (also known as Ellingwood Route or Ellingwood Ledges or some combination thereof) is a popular technical climbing route on Crestone Needle in Colorado's Sangre de Cristo Range. The Ellingwood Ledges Route is recognized in the historic climbing text ''Fifty Classic Climbs of North America''.Louis W. Dawson II, ''Dawson's Guide to Colorado's Fourteeners, Volume 2'', Blue Clover Press, 1999, , Route 2.1.4. An "arete" is "a sharp narrow ridge found in rugged mountains". Albert R. Ellingwood was a pioneering member of the Colorado Mountain Club and the first to climb the Crestones On these climbs including the 1925 ascent of the arete,Ellingwood was partnered with the long lived Eleanor Davis. The route is technically difficult, and the site of multiple climbing fatalities. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sea Level Datum Of 1929
The National Geodetic Vertical Datum of 1929 is the official name since 1973 of the vertical datum established for vertical control surveying in the United States, United States of America by the General Adjustment of 1929. Originally known as Sea Level Datum of 1929, NGVD 29 was determined and published by the National Geodetic Survey and used to measure the elevation of a point above and depression (geology), depression below mean sea level (MSL). NGVD29 was superseded by the North American Vertical Datum of 1988 (NAVD 88), based upon reference to a single benchmark (referenced to the new International Great Lakes Datum of 1985 local mean sea level height value), although many cities and U.S. Army Corps of Engineers "legacy" projects with established data continued to use the older datum. Methodology Mean sea level was measured at 26 tide gauges: 21 in the United States and 5 in Canada. The datum was defined by the observed heights of mean sea level at the 26 tide gauges and ...

Crestone, Colorado
Description The Town of Crestone is a Statutory Town in Saguache County, Colorado, United States. The town population was 141 at the 2020 United States Census. Crestone is a small village at the foot of the western slope of the Sangre de Cristo Range, in the northern part of the San Luis Valley. Crestone was platted in 1880 by George Adams, owner of the neighboring Luis Maria Baca Grant No. 4. In the 1970s the Baca Grande, a large land development, was established on the lands of the Baca Grant to the south and west. Several hundred homes have been built there. The Crestone area, which includes the Baca Grande and Moffat, Colorado, is a spiritual center for several world religions, including: a Hindu temple, a Zen center, several Tibetan Buddhist centers, and miscellaneous New Age happenings. Much of this spiritual development was catalyzed by the couple Hanne Strong and Maurice Strong in the 1970s, who set out to make it an interfaith center. Crestone is accessible to vis ...

List Of Colorado Fourteeners
This is a list of mountain peaks in the U.S. State of Colorado that exceed of elevation. In the mountaineering parlance of the Western United States, a ''fourteener'' is a mountain peak with an elevation of at least 14,000 feet. This is a complete list of the 53 fourteeners in the U.S. State of Colorado with at least of topographic prominence. See the main fourteener article, which has a list of all of the fourteeners in the United States, for some information about how such lists are determined and caveats about elevation and ranking accuracy. The summit of a mountain or hill may be measured in three principal ways: #The topographic elevation of a summit measures the height of the summit above a geodetic sea level.All elevations in the 48 states of the contiguous United States include an elevation adjustment from the National Geodetic Vertical Datum of 1929 (NGVD 29) to the North American Vertical Datum of 1988 (NAVD 88).

Conglomerate (geology)
Conglomerate () is a clastic sedimentary rock that is composed of a substantial fraction of rounded to subangular gravel-size clasts. A conglomerate typically contains a matrix of finer-grained sediments, such as sand, silt, or clay, which fills the interstices between the clasts. The clasts and matrix are typically cemented by calcium carbonate, iron oxide, silica, or hardened clay. Conglomerates form by the consolidation and lithification of gravel. They can be found in sedimentary rock sequences of all ages but probably make up less than 1 percent by weight of all sedimentary rocks. In terms of origin and depositional mechanisms, they are closely related to sandstones and exhibit many of the same types of sedimentary structures, e.g., tabular and trough cross-bedding and graded bedding.Boggs, S. (2006) ''Principles of Sedimentology and Stratigraphy.'', 2nd ed. Prentice Hall, New York. 662 pp. Friedman, G.M. (2003) ''Classification of sediments and sedimentary rocks.'' In G ...

Granite
Granite () is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths exposed over hundreds of square kilometers. Granite is typical of a larger family of ''granitic rocks'', or ''granitoids'', that are composed mostly of coarse-grained quartz and feldspars in varying proportions. These rocks are classified by the relative percentages of quartz, alkali feldspar, and plagioclase (the QAPF classification), with true granite representing granitic rocks rich in quartz and alkali feldspar. Most granitic rocks also contain mica or amphibole minerals, though a few (known as leucogranites) contain almost no dark minerals. Granite is nearly alway ...

Fifty Classic Climbs Of North America
''Fifty Classic Climbs of North America'' is a climbing guidebook and history written by Steve Roper and Allen Steck. It is considered a classic piece of climbing literature, known to many climbers as simply "The Book", and has served as an inspiration for more recent climbing books, such as Mark Kroese's ''Fifty Favorite Climbs''. Though much of the book's contents are now out of date, it is still recognized as a definitive text which goes beyond the traditional guidebook. History The first edition was published in 1979, by Sierra Club Books in the United States and in Great Britain by the now-defunct Diadem Books. This was followed by a paperback printing by Random House in 1981. Two subsequent editions (with the same content) were published by Sierra Club Books in 1982 and 1996. Between 1979 and 1999 it sold nearly thirty thousand copies, a considerable achievement for a climbing guide book. Reviewing the book in ''American Alpine Journal The ''American Alpine Journal' ...

Yosemite Decimal System
The Yosemite Decimal System (YDS) is a three-part system used for rating the difficulty of walks, hikes, and climbs, primarily used by mountaineers in the United States and Canada. It was first devised by members of the Sierra Club in Southern California in the 1950s as a refinement of earlier systems, particularly those developed in Yosemite Valley, and quickly spread throughout North America. Description The class 5 portion of the class scale is primarily a rock climbing classification system, while classes 1–2 are used mainly in hiking and trail running. Class 3 describes easy and moderate climbing (i.e. scrambling), with varying amounts of exposure (length of a possible fall). Class 4 is an "in-between" rating that describes a very exposed scramble, corresponding roughly to the IFAS classification of PD+. Climbers, specifically those involved with technical class 5 climbing, often abbreviate "class 3" and "class 4" to "3rd" and "4th" respectively. Originally the system was ...

Columbia Point
Columbia Point is a high mountain summit of the Crestones in the Sangre de Cristo Range of the Rocky Mountains of North America. The thirteener is located east by south ( bearing 102°) of the Town of Crestone in Saguache County, Colorado, United States. The Crestones are a cluster of high summits in the Sangre de Cristo Range, comprising Crestone Peak, Crestone Needle, Kit Carson Peak, Challenger Point, Humboldt Peak, and Columbia Point. Columbia Point is subpeak of Kit Carson Mountain. It was known informally as Kat Carson, but was officially named Columbia Point in 2003 to honor the seven astronauts who died when the Space Shuttle Columbia disintegrated during re-entry on February 1, 2003. With a topographic prominence over , it qualifies as a separate summit under the standard cutoff, but it is not a well-known peak. The Memorial The USGS Board of Geographic Names approved the name of Columbia Point in June, 2003. On the weekend of August 7, 2003, a group consi ...

Humboldt Peak (Colorado)
Humboldt Peak is a high mountain summit of the Crestones in the Sangre de Cristo Range of the Rocky Mountains of North America. The fourteener is located in the Sangre de Cristo Wilderness of San Isabel National Forest, south-southwest ( bearing 204°) of the Town of Westcliffe in Custer County, Colorado, United States. The Crestones are a cluster of high summits in the Sangre de Cristo Range, comprising Crestone Peak, Crestone Needle, Kit Carson Peak, Challenger Point, Humboldt Peak, and Columbia Point. The mountain was named in honor of German naturalist and explorer Alexander von Humboldt. Climbing The standard route on the peak is a hike along a trail, with rock scrambling (Class 2) near the summit. The trail climbs the peak from the South Colony Lakes basin, accessed from the east side of the range. This basin is a popular site that is also the base for most climbs of Crestone Peak and Crestone Needle. See also *List of Colorado fourteeners *List of mountain peaks ...
