Mount Hesperus (Alaska)
Mount Hesperus is the highest peak of the Revelation Mountains, the westernmost subrange of the Alaska Range. The Revelations are a small, rarely visited range, but they contain dramatic rock peaks, rising from low bases. Mount Hesperus is particularly impressive in terms of local relief: for example, it drops over 7,500 feet (2,286m) in less than 2 miles (3,219m) on two sides. Such steepness for this amount of relief makes Hesperus comparable to the best peaks in North America. Mount Hesperus lies to the north of most of the other peaks of the Revelation Mountains, between two forks of the Big River. To the southwest of the peak lies the Revelation Glacier. The peak is over 100 miles from the closest significant airport. The first ascent of Mount Hesperus was on May 2, 1985, by Justin Lesueur (New Zealand) and Karl Swanson, Stephen Spalding (Alaska). They first attempted routes on the northeast side of the peak, and then successfully ascended a route on the southwest face, whi ...

Revelation Mountains
The Revelation Mountains are a small, rugged subrange of the Alaska Range in Alaska, United States. They mark the furthest western extent of the Alaska Range. The range is rarely visited because of the flying time necessary to get there and also because of the notoriously poor weather conditions that are prevalent in the range. The highest peak in the range is Mount Hesperus (9,828 feet/2,996 m). Description The Revelation Mountains are located approximately west-northwest of Anchorage, and approximately 130 miles (210 km) southwest of Denali. They are accessed by small plane; the closest airports to the range are near Anchorage and in Talkeetna, which is also approximately 130 miles (210 km) away. This makes access to the range very expensive; the weather also creates the potential for delays in reaching the range (both to drop off climbers and to pick them up). The principal peaks of the Revelation Mountains are granite spires, rising out of relatively low-elevation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alaska Range
The Alaska Range is a relatively narrow, mountain range in the Southcentral Alaska, southcentral region of the U.S. state of Alaska, from Lake Clark at its southwest endSources differ as to the exact delineation of the Alaska Range. ThBoard on Geographic Namesentry is inconsistent; part of it designates Iliamna Lake as the southwestern end, and part of the entry has the range ending at the Telaquana and Neacola Rivers. Other sources identify Lake Clark, in between those two, as the endpoint. This also means that the status of the Neacola Mountains is unclear: it is usually identified as the northernmost subrange of the Aleutian Range, but it could also be considered the southernmost part of the Alaska Range. to the White River (Yukon), White River in Canada's Yukon Territory in the southeast. Denali, the highest mountain in North America, is in the Alaska Range. The range is part of the American Cordillera. The Alaska Range is one of the highest mountain ranges in the world, afte ...

United States Geological Survey
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of planets and moons, based on data from U.S. space probes. The sole scientific agency of the U.S. Department of the Interior, USGS is a fact-finding research organization with no regulatory responsibility. It is headquartered in Reston, Virginia, with major offices near Lakewood, Colorado; at the Denver Federal Center; and in NASA Research Park in California. In 2009, it employed about 8,670 people. The current motto of the USGS, in use since August 1997, is "science for a changing world". The agency's previous slogan, adopted on its hundredth anniversary, was "Earth Science in the Pub ...

List Of Mountain Peaks Of The United States
This article comprises three sortable tables of major mountain peaks of the United States of America.

Landforms Of Bethel Census Area, Alaska
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratum, stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic b ...

Two-thousanders Of The United States
Two-thousanders are mountains that have a height of at least 2,000 metres above sea level, but less than 3,000 metres. The term is used in Alpine circles, especially in Europe (e.g. German: ''Zweitausender''). The two photographs show two typical two-thousanders in the Alps that illustrate different types of mountain. The Säuling (top) is a prominent, individual peak, whereas the Schneeberg (bottom) is an elongated limestone massif. In ranges like the Allgäu Alps, the Gesäuse or the Styrian-Lower Austrian Limestone Alps the mountain tour descriptions for mountaineers or hikers commonly include the two-thousanders, especially in areas where only a few summits exceed this level. Examples from these regions of the Eastern Alps are: * the striking Nebelhorn (2,224 m) near Oberstdorf or the Säuling (2,047 m) near Neuschwanstein, * the Admonter Reichenstein (2,251 m), Eisenerzer Reichenstein (2,165 m), Großer Pyhrgas (2,244 m) or Hochtor (2,3 ...
