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 United States Coast and 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 NGVD29 was superseded by the North American Vertical Datum of 1988 (NAVD 88), based upon reference to a single benchmark (referenced to the new International Great Lakes Datum of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 five in Canada. The datum was defined by the observed heights of mean sea level at the ...

Mountain
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are inselberg, isolated summits, but most occur in mountain ranges. mountain formation, Mountains are formed through tectonic plate, tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through Slump (geology), slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce Alpine climate, colder climates than at sea level at similar latitude. These colder climates strongly affect the Montane ecosystems, ecosystems of mountains: different elevations hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Juan Mountains (Colorado)
The San Juan Mountains is a high and rugged mountain range in the Rocky Mountains in southwestern Colorado and northwestern New Mexico. The area is highly mineralized (the Colorado Mineral Belt) and figured in the gold and silver mining industry of early Colorado. Major towns, all old mining camps, include Creede, Lake City, Silverton, Ouray, and Telluride. Large scale mining has ended in the region, although independent prospectors still work claims throughout the range. The last large-scale mines were the Sunnyside Mine near Silverton, which operated until late in the 20th century, and the Idarado Mine on Red Mountain Pass, which closed in the 1970s. Famous old San Juan mines include the Camp Bird and Smuggler Union mines, both located between Telluride and Ouray. The Summitville mine was the scene of a major environmental disaster in the 1990s when the liner of a cyanide-laced tailing pond began leaking heavily. Summitville is in the Summitville caldera, one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Mountain Peaks Of Colorado
This is a list of major mountain peaks in the U.S. State of Colorado. This article comprises three sortable tables of major mountain peaks in Colorado. 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. The first table below ranks the 55 highest major summits of Colorado by elevation. #The topographic prominence of a summit is a measure of how high the summit rises above its surroundings. The second table below ranks the 50 most prominent summits of Colorado. #The topographic isolation (or radius of dominance) of a summit measures how far the summit lies from its nearest point of equal elevation. The third table below ranks the 50 most isolated major summits of Colorado. __TOC__ Highest major summits Of the highest major summits of Colorado, the following 63 peaks exceed elevation and 117 peaks exceed elevation.

Cumbres Pass
Cumbres Pass, elevation , is a mountain pass in the San Juan Mountains in Colorado, United States. The pass is traversed by State Highway 17 and the Cumbres and Toltec Scenic Railroad. The highway has a moderate 5.8% approach on the north side and a gentler, 4% approach on the south side. It is rarely closed in winter and does not normally cause problems for vehicles, since the road is not a major through highway. Railroad The railroad line was built in the early 1880s by the Denver & Rio Grande Railroad as part of its San Juan Extension from Alamosa to Durango, Colorado. The railroad has a steep (for a railroad) 4% grade approaching from the west, so additional helper locomotives were usually run (and often still are) on trains from Chama, New Mexico to Cumbres Pass. The facilities at the pass were built by the railroad to support the turning of the helper locomotives for their return to Chama, and provide water to locomotives after the climb. Some of the structures at the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Absolute Bearing
In navigation, bearing or azimuth is the horizontal angle between the direction of an object and north or another object. The angle value can be specified in various angular units, such as degrees, mils, or grad. More specifically: * Absolute bearing refers to the clockwise angle between the magnetic north (''magnetic bearing'') or true north (''true bearing'') and an object. For example, an object to due east would have an absolute bearing of 90 degrees. Thus, it is the same as azimuth.U.S. Army, ''Advanced Map and Aerial Photograph Reading'', Headquarters, War Department, Washington, D.C. (17 September 1941), pp. 24-2/ref> * #Relative, Relative bearing refers to the angle between the craft's forward direction ( heading) and the location of another object. For example, an object relative bearing of 0 degrees would be immediately in front; an object relative bearing 180 degrees would be behind. Bearings can be measured in mils, points, or degrees. Thus, it is the same as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rio Grande National Forest
Rio Grande National Forest is a 1.86 million-acre (7,530 km2) U.S. National Forest located in southwestern Colorado. The forest encompasses the San Luis Valley, which is the world's largest agricultural alpine valley, as well as one of the world's largest high deserts located around mountains. The Rio Grande rises in the forest, and the Continental Divide runs along most of its western border. The forest lies in parts of nine counties. In descending order of land area within the forest they are Saguache, Mineral, Conejos, Rio Grande, Hinsdale, San Juan, Alamosa, Archuleta, and Custer counties. Forest headquarters are currently located in Del Norte, Colorado. There are local ranger district offices in Del Norte, La Jara, and Saguache. Wilderness areas There are four officially designated wilderness areas lying within Rio Grande National Forest that are part of the National Wilderness Preservation System. All of them extend partially into neighboring National Fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South San Juan Wilderness
The South San Juan Wilderness is a U.S. Wilderness Area located in the San Juan National Forest, east of Pagosa Springs, Colorado, Pagosa Springs, in southern Colorado. The area, which spans 158,790 acres, was designated a Wilderness Area and put into the National Wilderness Preservation System in 1980 by the United States Congress. The Conejos River, Conejos, San Juan River (Colorado River tributary), San Juan, and Rio Blanco (Colorado), Blanco rivers all begin in the area. The last known grizzly bear in Colorado was killed in the wilderness in 1979. Some believe that it is still home to a few grizzlies, but there is no sufficient evidence yet to prove this. Recreation The wilderness area contains: 32 lakes, many peaks above , the highest of which is Summit Peak at 13,307 feet, and of hiking trails, that includes of the Continental Divide Trail.

Thirteener
In mountaineering in the United States, a thirteener (abbreviated 13er) is a mountain that exceeds above mean sea level, similar to the more familiar "fourteeners," which exceed . In most instances, "thirteeners" refers only to those peaks between 13,000 and 13,999 feet in elevation. The importance of thirteeners is greatest in Colorado, which has the majority of such peaks in North America with over 600 of them. Despite the large number of peaks, over 20 peak bagging, peak baggers have reported climbing all of Colorado's thirteeners. Thirteeners are also significant in states whose List of U.S. states by elevation, highpoints fall between 13,000 and 13,999 feet. For example, the Wyoming thirteeners are the highest peaks within the state, and only 5 individuals have reported climbing all 35 peaks, likely due to a combination of technical difficulty and remoteness. In 2019, Teresa Gergen became the first person to summit all 846 thirteeners outside of Alaska, an accomplishment th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Summit
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. For summits that are permanently covered in significant layers of ice, the height may be measured by the highest point of rock (rock height) or the highest point of permanent solid ice (snow height). The highest summit in the wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
