Southern Rockies
The Southern Rocky Mountains are a major subregion of the Rocky Mountains of North America located in the southeastern portion of the U.S. state of Wyoming, the central and western portions of Colorado, the northern portion of New Mexico, and extreme eastern portions of Utah. The Southern Rocky Mountains are also commonly known as the Southern Rockies, and since the highest peaks are located in the State of Colorado, they are sometimes known as the Colorado Rockies, although many important ranges and peaks rise in the other three states. The Southern Rockies include the highest mountain ranges of the Rocky Mountains and include all 30 of the highest major peaks of the Rockies. The Southern Rocky Mountains are generally divided from the Western Rocky Mountains by the Green River and the Colorado River below the Green River. The Southern Rockies are divided from the Central Rocky Mountains by South Pass in Wyoming and the drainage running east from the pass down the Sweetw ...

Sweetwater River (Wyoming)
The Sweetwater River is a long tributary of the North Platte River,U.S. Geological Survey. National Hydrography Dataset high-resolution flowline dataThe National Map accessed March 21, 2011 in the U.S. state of Wyoming. As a part of the Mississippi River system, its waters eventually reach the Gulf of Mexico. Course The Sweetwater rises in southwestern Fremont County, at the continental divide near South Pass Wyoming, on the southern end of the Wind River Range. It flows ENE along the north side of the Antelope Hills, then ESE, through Fremont County, past Jeffrey City, between the Granite Mountains to the north and the Green Mountains (Wyoming) to the south, through what are now cattle-raising areas. In southern Natrona County, it passes Devil's Gate and Independence Rock along the Oregon, California and Mormon Trails, and empties into the North Platte as the Sweetwater arm of Pathfinder Reservoir.

NGVD 29
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 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 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 NGVD29 was superseded by the North American Vertical Datum of 1988 (NAVD 88), based upon reference to a single benchmark (referenced to the new International Great Lakes Datum of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 by the set of elevations of all benc ...

Ultra-prominent Summit
An ultra-prominent peak, or Ultra for short, is a mountain summit with a topographic prominence of or more; it is also called a P1500. The prominence of a peak is the minimum height of climb to the summit on any route from a higher peak, or from sea level if there is no higher peak. There are approximately 1,524 such peaks on Earth. Some well-known peaks, such as the Matterhorn and Eiger, are not Ultras because they are connected to higher mountains by high cols and therefore do not achieve enough topographic prominence. The term "Ultra" originated with earth scientist Steve Fry, from his studies of the prominence of peaks in Washington in the 1980s. His original term was "ultra major mountain", referring to peaks with at least of prominence. Distribution Currently, 1,518 Ultras have been identified above sea level: 639 in Asia, 356 in North America, 209 in South America, 120 in Europe (including 12 in the Caucasus), 84 in Africa, 69 in Oceania, and 41 in Antarctica.

Topographic Prominence
In topography, prominence (also referred to as autonomous height, relative height, and shoulder drop in US English, and drop or relative height in British English) measures the height of a mountain or hill's summit relative to the lowest contour line encircling it but containing no higher summit within it. It is a measure of the independence of a summit. A peak's ''key col'' (the highest col surrounding the peak) is a unique point on this contour line and the ''parent peak'' is some higher mountain, selected according to various criteria. Definitions The prominence of a peak may be defined as the least drop in height necessary in order to get from the summit to any higher terrain. This can be calculated for a given peak in the following way: for every path connecting the peak to higher terrain, find the lowest point on the path; the ''key col'' (or ''key Saddle point, saddle'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting pat ...

Jemez Mountains
The Jemez Mountains are a group of mountains in Rio Arriba, Sandoval, and Los Alamos counties, New Mexico, United States. Numerous Puebloan Indian tribes have lived in the Jemez Mountains region since before the Spanish arrived in New Mexico. The Pueblo Indians of this region are the Towa-speaking Jemez people for which this mountain range is named, the Keres-speaking Keresan Indians, and the Tewa-speaking Tewa Indians. Tsąmpiye'ip'įn is the Tewa language name for the Jemez Mountains. The highest point in the range is Chicoma Mountain (also spelled as Tschicoma or Tchicoma) at an elevation of . The town of Los Alamos and the Los Alamos National Laboratory adjoin the eastern side of the range while the town of Jemez Springs is to the west. Pajarito Mountain Ski Area is the only ski area in the Jemez. New Mexico State Highway 4 is the primary road that provides vehicular access to locations in the Jemez Mountains.

California Trail
The California Trail was an emigrant trail of about across the western half of the North American continent from Missouri River towns to what is now the state of California. After it was established, the first half of the California Trail followed the same corridor of networked river valley trails as the Oregon Trail and the Mormon Trail, namely the valleys of the Platte, North Platte, and Sweetwater rivers to Wyoming. The trail has several splits and cutoffs for alternative routes around major landforms and to different destinations, with a combined length of over . Introduction By 1847, two former fur trading frontier forts marked trailheads for major alternative routes through Utah and Wyoming to Northern California. The first was Jim Bridger's Fort Bridger (est. 1842) in present-day Wyoming on the Green River, where the Mormon Trail turned southwest over the Wasatch Range to the newly established Salt Lake City, Utah. From Salt Lake the Salt Lake Cutoff (est. 1848) ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mormon Trail
The Mormon Trail is the long route from Illinois to Utah that members of the Church of Jesus Christ of Latter-day Saints traveled for 3 months. Today, the Mormon Trail is a part of the United States National Trails System, known as the Mormon Pioneer National Historic Trail. The Mormon Trail extends from Nauvoo, Illinois, which was the principal settlement of the Latter Day Saints from 1839 to 1846, to Salt Lake City, Utah, which was settled by Brigham Young and his followers beginning in 1847. From Council Bluffs, Iowa to Fort Bridger in Wyoming, the trail follows much the same route as the Oregon Trail and the California Trail; these trails are collectively known as the Emigrant Trail. The Mormon pioneer run began in 1846, when Young and his followers were driven from Nauvoo. After leaving, they aimed to establish a new home for the church in the Great Basin and crossed Iowa. Along their way, some were assigned to establish settlements and to plant and harvest crops for lat ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Oregon Trail
The Oregon Trail was a east–west, large-wheeled wagon route and Westward Expansion Trails, emigrant trail in the United States that connected the Missouri River to valleys in Oregon. The eastern part of the Oregon Trail spanned part of what is now the state of Kansas and nearly all of what are now the states of Nebraska and Wyoming. The western half of the trail spanned most of the current states of Idaho and Oregon. The Oregon Trail was laid by fur traders and trappers from about 1811 to 1840 and was only passable on foot or on horseback. By 1836, when the first migrant wagon train was organized in Independence, Missouri, a wagon trail had been cleared to Fort Hall, Idaho. Wagon trails were cleared increasingly farther west and eventually reached all the way to the Willamette Valley in Oregon, at which point what came to be called the Oregon Trail was complete, even as almost annual improvements were made in the form of bridges, cutoffs, ferries, and roads, which made the t ...

Rocky Mountain Region
The Rocky Mountains, also known as the Rockies, are a major mountain range and the largest mountain system in North America. The Rocky Mountains stretch in straight-line distance from the northernmost part of western Canada, to New Mexico in the southwestern United States. Depending on differing definitions between Canada and the U.S., its northern terminus is located either in northern British Columbia's Terminal Range south of the Liard River and east of the Trench, or in the northeastern foothills of the Brooks Range/ British Mountains that face the Beaufort Sea coasts between the Canning River and the Firth River across the Alaska-Yukon border. Its southernmost point is near the Albuquerque area adjacent to the Rio Grande rift and north of the Sandia–Manzano Mountain Range. Being the easternmost portion of the North American Cordillera, the Rockies are distinct from the tectonically younger Cascade Range and Sierra Nevada, which both lie farther to its west.
