Hilliard Peak
Hilliard Peak is a mountain summit in Pitkin County, Colorado, Pitkin County, Colorado, United States. Description Hilliard Peak is located west of the Continental Divide in the Elk Mountains (Colorado), Elk Mountains which are a subrange of the Rocky Mountains. It ranks as the 306th-highest peak in Colorado. The mountain is situated south-southwest of the community of Aspen, Colorado, Aspen and west-northwest of Castle Peak (Colorado), Castle Peak. The peak is set in the Maroon Bells–Snowmass Wilderness on land managed by White River National Forest.

Topographic Relief
Terrain or relief (also topographical relief) involves the vertical and horizontal dimensions of land surface. The term bathymetry is used to describe underwater relief, while hypsometry studies terrain relative to sea level. The Latin word (the root of ''terrain'') means "earth." In physical geography, terrain is the lay of the land. This is usually expressed in terms of the elevation, slope, and orientation of terrain features. Terrain affects surface water flow and distribution. Over a large area, it can affect weather and climate patterns. Importance The understanding of terrain is critical for many reasons: * The terrain of a region largely determines its suitability for human settlement: flatter alluvial plains tend to have better farming soils than steeper, rockier uplands. * In terms of environmental quality, agriculture, hydrology and other interdisciplinary sciences; understanding the terrain of an area assists the understanding of watershed boundaries, drai ...

Pyramid Peak (Colorado)
Pyramid Peak is a fourteen-thousand-foot mountain in the U.S. state of Colorado. It is the 47th highest mountain peak in Colorado, and 78th highest peak in the United States. It is located in the Elk Mountains in southeastern Pitkin County, approximately southwest of Aspen. The summit somewhat resembles a ragged square pyramid and is visible from the Roaring Fork River valley north of Aspen along the canyon of Maroon Creek. Like many of the peaks in the Elks, Pyramid Peak is quite steep, especially compared to more gentle fourteeners such as Mount Elbert. For example, the peak's summit rises above Crater Lake to the northwest in only , and above East Maroon Creek to the east of the peak in the same horizontal distance. Climbing The standard climbing routes on Pyramid Peak are the northeast and northwest ridges (the latter is also known as the "Keyhole Route"). These routes involve difficult route finding (very difficult, in the case of the northwest ridge), high expo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 baggers have reported climbing all of Colorado's thirteeners. Thirteeners are also significant in states whose 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. Not all summits over 13,000 feet qualify as thirteeners, but only those summits that mountaineers consider to be independent. Objective standards for indepen ...

Subarctic Climate
The subarctic climate (also called subpolar climate, or boreal climate) is a climate with long, cold (often very cold) winters, and short, warm to cool summers. It is found on large landmasses, often away from the moderating effects of an ocean, generally at latitudes from 50° to 70°N, poleward of the humid continental climates. Subarctic or boreal climates are the source regions for the cold air that affects temperate latitudes to the south in winter. These climates represent Köppen climate classification ''Dfc'', ''Dwc'', ''Dsc'', ''Dfd'', ''Dwd'' and ''Dsd''. Description This type of climate offers some of the most extreme seasonal temperature variations found on the planet: in winter, temperatures can drop to below and in summer, the temperature may exceed . However, the summers are short; no more than three months of the year (but at least one month) must have a 24-hour average temperature of at least to fall into this category of climate, and the coldest month should ave ...

Köppen Climate Classification
The Köppen climate classification is one of the most widely used climate classification systems. It was first published by German-Russian climatologist Wladimir Köppen (1846–1940) in 1884, with several later modifications by Köppen, notably in 1918 and 1936. Later, the climatologist Rudolf Geiger (1894–1981) introduced some changes to the classification system, which is thus sometimes called the Köppen–Geiger climate classification system. The Köppen climate classification divides climates into five main climate groups, with each group being divided based on seasonal precipitation and temperature patterns. The five main groups are ''A'' (tropical), ''B'' (arid), ''C'' (temperate), ''D'' (continental), and ''E'' (polar). Each group and subgroup is represented by a letter. All climates are assigned a main group (the first letter). All climates except for those in the ''E'' group are assigned a seasonal precipitation subgroup (the second letter). For example, ''Af'' indi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maroon Bells
The Maroon Bells are two peaks in the Elk Mountains, Maroon Peak and North Maroon Peak, separated by about half a kilometer (0.3 miles). The mountains are on the border between Pitkin County and Gunnison County, Colorado, United States, about southwest of Aspen. Both peaks are fourteeners. Maroon Peak, at , is the 27th highest peak in Colorado. North Maroon Peak, at , is the 50th highest (depending on how they are counted). The view of the Maroon Bells to the southwest from the Maroon Creek valley is very heavily photographed. The peaks are located in the Maroon Bells–Snowmass Wilderness of White River National Forest. Maroon Bells-Snowmass Wilderness was one of five areas in Colorado designated as wilderness in the original Wilderness Act of 1964. The Wilderness area surrounds the extremely popular Maroon Bells Scenic Area, which is a major access point for Wilderness travel. Geology The Maroon Bells are composed of Maroon Formation mudstone. Mudstone is weak and fractur ... [...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, ...

United States Board On Geographic Names
The United States Board on Geographic Names (BGN) is a federal body operating under the United States Secretary of the Interior. The purpose of the board is to establish and maintain uniform usage of geographic names throughout the federal government of the United States. History On January 8, 1890, Thomas Corwin Mendenhall, superintendent of the US Coast and Geodetic Survey Office, wrote to 10 noted geographers "to suggest the organization of a Board made up of representatives from the different Government services interested, to which may be referred any disputed question of geographical orthography." President Benjamin Harrison signed executive order 28 on September 4, 1890, establishing the ''Board on Geographical Names''. "To this Board shall be referred all unsettled questions concerning geographic names. The decisions of the Board are to be accepted y federal departmentsas the standard authority for such matters." The board was given authority to resolve all unsettled ques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
