Hess Mountain
Hess Mountain, also known as Mount Hess, is an elevation glaciated summit located on the crest of the Alaska Range, in Alaska, United States. It is the seventh-highest peak in the Hayes Range, a subset of the Alaska Range. This remote peak is situated west of Mount Hayes, and south of Fairbanks. Mount Deborah, the nearest higher neighbor, is positioned to the west. The mountain's name was reported in 1912 by the United States Geological Survey. The first ascent was made May 24, 1951, by Alston Paige, Dick Holdren, Ed Huizer, Howard Bowman, and Elton Thayer. The first ascent via the North Ridge was made May 23, 1976, by Steven Hackett and Thomas Hillis. Climate Based on the Köppen climate classification, Hess Mountain is located in a subarctic climate zone with long, cold, snowy winters, and mild summers. Temperatures can drop below −20 °C with wind chill factors below −30 °C. This climate supports the Gillam and West Fork Glaciers surrounding this peak. Th ...

Mount Deborah
Mount Deborah is a mountain in the U.S. state of Alaska. It is one of the major peaks of the eastern Alaska Range. Despite its low absolute elevation (compared to other major peaks in North America), it is a particularly large and steep peak in terms of its quick rise over local terrain. For example, the Northeast Face rises 7000 feet (2135m) in approximately 1.5 miles (2.4 km). This steepness, combined with difficult access, harsh weather, and classic Alaskan ice and snow features, make this a challenging peak to climb. Mount Deborah was named in 1907 by James Wickersham for his first wife, Deborah Susan (Bell) Wickersham. First ascent Mount Deborah was first climbed in 1954 by Fred Beckey, Henry Meybohm, Heinrich Harrer, via the South Ridge. Notable attempts and ascents * 1953 ''South Ridge'' (attempt) by Al Paige, Howard Bowman, Brooke Marston, Doctor McFarland. * 1964 ''East Ridge'' (attempt) by David Roberts and Don Jensen. * 1975 ''West Buttress and South Ridge'' F ...

Surface Runoff
Surface runoff (also known as overland flow) is the flow of water occurring on the ground surface when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is saturated by water to its full capacity, and the rain arrives more quickly than the soil can absorb it. Surface runoff often occurs because impervious areas (such as roofs and pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or man-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. Runoff that occurs on the ground surface before reaching a channel can be a nonpoint source of pollution, as it can carry man-made contaminants or natural forms of pollution (such as rotting leaves). Man-made contaminants in runoff i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Denali Borough, Alaska
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 ...

Alaska Mountain Range
Alaska ( ; russian: Аляска, Alyaska; ale, Alax̂sxax̂; ; ems, Alas'kaaq; Yup'ik: ''Alaskaq''; tli, Anáaski) is a state located in the Western United States on the northwest extremity of North America. A semi-exclave of the U.S., it borders the Canadian province of British Columbia and the Yukon territory to the east; it also shares a maritime border with the Russian Federation's Chukotka Autonomous Okrug to the west, just across the Bering Strait. To the north are the Chukchi and Beaufort Seas of the Arctic Ocean, while the Pacific Ocean lies to the south and southwest. Alaska is by far the largest U.S. state by area, comprising more total area than the next three largest states (Texas, California, and Montana) combined. It represents the seventh-largest subnational division in the world. It is the third-least populous and the most sparsely populated state, but by far the continent's most populous territory located mostly north of the 60th parallel, with a ...
