Snowmass Mountain
Snowmass Mountain is a mountain in the U.S. state of Colorado, and the thirty-fourth highest mountain peak in the state. Located in the Elk Mountains within the Maroon Bells-Snowmass Wilderness of the White River National Forest, it lies along the border between Pitkin and Gunnison counties, west of Aspen and southwest of the town of Snowmass Village. Snowmass Mountain is named for the large snowfield that lies on its eastern slopes. Snowmass Mountain should not be confused with the Snowmass ski area, located outside Snowmass Village; nor with nearby Snowmass Peak, a lower but more visually striking peak that towers over Snowmass Lake. Hagerman Peak sits between Snowmass Mountain and Snowmass Peak and is also often mistaken for Snowmass Mountain. Hiking/climbing The route most commonly used to climb Snowmass Mountain is the Snowmass Creek approach. The route to the summit starts at Snowmass Lake, which is itself an hike up Snowmass Creek from the parking area. Most peop ...

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 NGVD29 was superseded by the North American Vertical Datum of 1988 (NAVD 88), based upon reference to a single benchmark (referenced to the new International Great Lakes Datum of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

Snowmass Peak
Snowmass Peak in the U.S. state of Colorado dominates the view from Snowmass Lake. It is often mistaken for Snowmass Mountain, the thirty-fourth highest mountain peak in the state, as well as for Hagerman Peak. Snowmass Peak is not really a peak but the lower end of Hagerman Peak's east ridge. Natural forced perspective causes the optical illusion that Snowmass Peak is higher than Hagerman Peak though it is actually 221 ft shorter than Hagerman's summit. This illusion combined with its striking rise behind Snowmass Lake justifies it being a named point on USGS topographical maps. It is located in the Elk Mountains, within the Maroon Bells-Snowmass Wilderness of the White River National Forest. It lies along the border between Pitkin and Gunnison counties, west of Aspen and southwest of the town of Snowmass Village. Hiking/climbing The route used to climb Snowmass Peak is the Trail Rider Pass trail to Hagerman Peak. This trail can be accessed by Snowmass Creek approach of ...

Mountains Of Pitkin County, Colorado
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 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through 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 slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...

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).

Crystal River (Colorado)
The Crystal River is a tributary of the Roaring Fork River, approximately long, in Gunnison and Pitkin counties in Colorado, United States. Description The river drains a glacial valley, called the Coal Basin, south of Carbondale which was historically known as a center of coal mining in southwestern Colorado. It rises in northern Gunnison County in the Elk Mountains on the north side of Schofield Pass, passing through the ghost town of Crystal City, still inhabited by a few summer residents. It then flows north past Marble, then into Pitkin County past Redstone. It joins the Roaring Fork below Carbondale. State Highway 133 follows the river along much of its route north of Marble. From Crystal City to Marble the river flows through the Crystal River Canyon, a narrow valley with numerous snowslide runs, rockfalls, and other hazardous terrain. Although it is locally known as a fishing and hiking attraction the unpaved and largely un-maintained mining road, designated ...

Geneva Lake (Colorado)
Geneva Lake (Potawatomi: ''Kishwauketoe'' 'Clear Water') is a body of freshwater in Walworth County in the southeastern portion of the U.S. state of Wisconsin. On its shores are the city of Lake Geneva and the villages of Fontana-on-Geneva-Lake and Williams Bay. The lake covers an area of approximately , with a maximum length of , a mean depth of , and a maximum depth of . Geologists believe that it is a filled-in kettle formed from a receding glacier. History Geneva Lake was home to a band of Prairie Potawatomi prior to colonial settlement. During the first three decades of the nineteenth century, the band was led by Big Foot. This led the settlers on Geneva Lake to refer to it as Big Foot Lake. In the 1830s, a government surveyor named John Brink renamed the lake and the town on it for Geneva, New York, another lakeside town which he thought they resembled. To avoid confusion with the nearby town of Geneva, Illinois, the city was renamed ''Lake Geneva''; later, the lake ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rockfall
A rockfall or rock-fallWhittow, John (1984). ''Dictionary of Physical Geography''. London: Penguin, 1984. . is a quantity/sheets of rock that has fallen freely from a cliff face. The term is also used for collapse of rock from roof or walls of mine or quarry workings. "A rockfall is a fragment of rock (a block) detached by sliding, toppling, or falling, that falls along a vertical or sub-vertical cliff, proceeds down slope by bouncing and flying along ballistic trajectories or by rolling on talus or debris slopes." Alternatively, a "rockfall is the natural downward motion of a detached block or series of blocks with a small volume involving free falling, bouncing, rolling, and sliding". The mode of failure differs from that of a rockslide. Causal mechanisms Favourable geology and climate are the principal causal mechanisms of rockfall, factors that include intact condition of the rock mass, discontinuities within the rockmass, weathering susceptibility, ground and surface water, ...

Scree
Scree is a collection of broken rock fragments at the base of a cliff or other steep rocky mass that has accumulated through periodic rockfall. Landforms associated with these materials are often called talus deposits. Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. The exact definition of scree in the primary literature is somewhat relaxed, and it often overlaps with both ''talus'' and ''colluvium''. The term ''scree'' comes from the Old Norse term for landslide, ''skriða'', while the term ''talus'' is a French word meaning a slope or embankment. In high-altitude arctic and subarctic regions, scree slopes and talus deposits are typically adjacent to hills and river valleys. These steep slopes usually originate from late-Pleistocene periglacial processes. Notable scree sites in Eastern North America include the Ice Caves at White Rocks National Recreation Area in southern Ve ...
