Castle Peak (Colorado)
Castle Peak is the ninth highest summit of the Rocky Mountains of North America and the U.S. state of Colorado. The prominent fourteener is the highest summit of the Elk Mountains and the Maroon Bells-Snowmass Wilderness. The peak is located northeast by north ( bearing 32°) of the Town of Crested Butte, Colorado, United States, on the drainage divide separating Gunnison National Forest and Gunnison County from White River National Forest and Pitkin County. The summit of Castle Peak is the highest point of both counties. Mountain Castle Peak takes its name from its castellated summit. The best climbing months are June, July, August, September through the Montezuma Glacier, a permanent snowfield between Castle and Conundrum Peaks. There are two standard routes for ascent. The Northwest Ridge features a moderate snow climb followed by an easy ridge scramble. It should not be attempted late in the summer when the of loose dirt and scree meet the climber near the t ...

Elk Mountains (Colorado)
The Elk Mountains are a high, rugged mountain range in the Rocky Mountains of west-central Colorado in the United States. The mountains sit on the western side of the Continental Divide, largely in southern Pitkin and northern Gunnison counties, in the area southwest of Aspen, south of the Roaring Fork River valley, and east of the Crystal River. The range sits west of the Sawatch Range and northeast of the West Elk Mountains. Much of the range is located within the White River National Forest and the Gunnison National Forest, as well as the Maroon Bells-Snowmass Wilderness and Raggeds Wilderness. The Elk Mountains rise nearly 9,000 ft. above the Roaring Fork Valley to the north. The highest peaks in the range are its fourteeners, Castle Peak (14,265 ft), Maroon Peak (14,156 ft), Capitol Peak (14,130 ft), Snowmass Mountain (14,092 ft), Pyramid Peak (14,018 ft), and North Maroon Peak (14,014 ft).North Maroon Peak does not meet the usua ...

Fourteener
In the mountaineering parlance of the Western United States, a fourteener is a mountain peak with an elevation of at least . The 96 fourteeners in the United States are all west of the Mississippi River. Colorado has the most (53) of any single state; Alaska is second with 29. Many peak baggers try to climb all fourteeners in the contiguous United States, one particular state, or another region. __TOC__ Qualification criteria The summit of a mountain or hill may be measured in three principal ways: # Topographic elevation is the height of the summit above a geodetic sea level.All elevations in the 48 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).

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'', or ''linking col'', or ''link'') is defined as the highest of these points, along all connecting paths; the pro ...

Eagle County, Colorado
Eagle County is a county located in the U.S. state of Colorado. As of the 2020 census, the population was 55,731. The county seat is the Town of Eagle and the most populous community is Edwards. The county is named for the Eagle River. Eagle County comprises the Edwards, CO Micropolitan Statistical Area. History Eagle County was created by the Colorado legislature on February 11, 1883, from portions of Summit County. It was named after the Eagle River, which runs through the county. The county seat was originally set in Red Cliff, Colorado, but was moved to the town of Eagle in 1921. The Ground Hog Mine, near Red Cliff, produced gold and silver in two vertical veins in 1887. One vein, or "chimney", contained gold in crystalline form, cemented by iron, while the other contained wire gold in the form of "ram's horns". One of these ram's horns is now on display in the Harvard Mineralogical Museum.Voynick, S.M., 1992, Colorado Gold, Missoula: Mountain Press Publishing Comp ...

Castellated
A battlement in defensive architecture, such as that of city walls or castles, comprises a parapet (i.e., a defensive low wall between chest-height and head-height), in which gaps or indentations, which are often rectangular, occur at intervals to allow for the launch of arrows or other projectiles from within the defences. These gaps are termed " crenels" (also known as ''carnels'', or '' embrasures''), and a wall or building with them is called crenellated; alternative (older) terms are castellated and embattled. The act of adding crenels to a previously unbroken parapet is termed crenellation. The function of battlements in war is to protect the defenders by giving them something to hide behind, from which they can pop out to launch their own missiles. A defensive building might be designed and built with battlements, or a manor house might be fortified by adding battlements, where no parapet previously existed, or cutting crenellations into its existing parapet wall.

North American Vertical Datum Of 1988
The North American Vertical Datum of 1988 (NAVD 88) is the vertical datum for orthometric heights established for vertical control surveying in the United States of America based upon the General Adjustment of the North American Datum of 1988. It superseded the National Geodetic Vertical Datum of 1929 (NGVD 29), previously known as the Sea Level Datum of 1929. NAVD 88, along with North American Datum of 1983 (NAD 83), is set to be replaced with a new GPS- and gravimetric geoid model-based geometric reference frame and geopotential datum in 2022. Methodology NAVD 88 was established in 1991 by the minimum-constraint adjustment of geodetic leveling observations in Canada, the United States, and Mexico. It held fixed the height of the primary tide gauge benchmark (surveying), referenced to the ''International Great Lakes Datum of 1985'' local mean sea level (MSL) height value, at Rimouski, Quebec, Canada. Additional tidal bench mark elevations were not used due to the de ... [...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 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 be ...

Drainage Divide
A drainage divide, water divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be difficult to discern. A triple divide is a point, often a summit, where three drainage basins meet. A ''valley floor divide'' is a low drainage divide that runs across a valley, sometimes created by deposition or stream capture. Major divides separating rivers that drain to different seas or oceans are continental divides. The term ''height of land'' is used in Canada and the United States to refer to a drainage divide. It is frequently used in border descriptions, which are set according to the "doctrine of natural boundaries". In glaciated areas it often refers to a low point on a divide where it ...
