Alaska Range
The Alaska Range is a relatively narrow, 600-mile-long (950 km) mountain range in the 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 in Canada's Yukon Territory in the southeast. The highest mountain in North America, Denali, is in the Alaska Range. It is part of the American Cordillera. The Alaska range is one of the higher ranges in the world after the Himalayas and the Andes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountains Of Denali National Park And Preserve
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 ...

DENALI NATIONAL PARK (MT
Denali (; also known as Mount McKinley, its former official name) is the highest mountain peak in North America, with a summit elevation of above sea level. With a topographic prominence of and a topographic isolation of , Denali is the third most prominent and third most isolated peak on Earth, after Mount Everest and Aconcagua. Located in the Alaska Range in the interior of the U.S. state of Alaska, Denali is the centerpiece of Denali National Park and Preserve. The Koyukon people who inhabit the area around the mountain have referred to the peak as "Denali" for centuries. In 1896, a gold prospector named it "Mount McKinley" in support of then-presidential candidate William McKinley; that name was the official name recognized by the federal government of the United States from 1917 until 2015. In August 2015, 40 years after Alaska had done so, the United States Department of the Interior announced the change of the Denali–Mount McKinley naming dispute, official name of ...

Radio Control Tower Denali Park
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraft ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Mount Frances
Mount Frances is a mountain summit located in the Kahiltna Glacier valley in the Alaska Range, in Denali National Park and Preserve, in the U.S. state of Alaska. It is situated north of the Kahiltna Glacier base camp for mountaineers attempting to climb Denali, Mount Foraker, or Mount Hunter (Alaska), Mount Hunter. The summit of Mt. Frances is the best viewpoint from which to see all three giants from one location. Mount Frances is set southwest of Denali, northwest of Mount Hunter, and northwest of Radio Control Tower. Access to the area is via air taxi from Talkeetna. The mountain's name honors Frances Randall (1925-1984), the first Denali Base Camp manager for nine climbing seasons (1974-1983). She was planning a tenth season, but cancer claimed her life. Her expertise was instrumental in coordinating many rescues that saved lives and earned her the nicknames ''Guardian Angel of McKinley'', and ''Kahiltna Queen''. She was a member of the Fairbanks Symphony Orchestra, often p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Hunter (Alaska)
Mount Hunter or Begguya is a mountain in Denali National Park in Alaska. It is approximately south of Denali, the highest peak in North America. "Begguya" means child (of Denali) in the Dena'ina language. Mount Hunter is the third-highest major peak in the Alaska Range. Mount Hunter has a complex structure: it is topped by a large, low-angled glacier plateau, connecting the North (Main) Summit and the South Summit (). Long, corniced ridges extend in various directions; between them are exceptionally steep faces. Naming of the mountain The native name for the mountain is Begguya, meaning "Denali's Child". Early prospectors referred to the mountain as Mount Roosevelt. In 1903, Robert Dunn, a reporter for the ''New York Commercial Advertiser'', visited the area as part of Frederick Cook's attempt to climb Mount McKinley. He bestowed the name of his aunt Anna Falconnet Hunter (1885–1941), who financed his trip, on a high nearby mountain, prominent from the northwest. This was, in ...

Denali Borough, Alaska
The Denali Borough is a borough located in the U.S. state of Alaska. As of the 2020 census the population of the borough was 1,619, down from 1,826 in 2010. The borough seat and most populated community is Healy, and its only incorporated place is Anderson. The borough was incorporated in December 1990. The area was previously a part of the Unorganized Borough, with the Upper Railbelt School District serving as the region's rural education attendance area (which was replaced by a school district under the borough's umbrella upon incorporation). The earliest inhabitants were nomadic native Alaskans. A mining camp was established near Healy prior to 1902, and construction of the Alaska Railroad brought additional settlers to the area in the early 1920s. Clear Space Force Station, the Usibelli Coal Mine and tourism at the Denali National Park and Preserve have brought growth and development. Geography The borough has a total area of , of which is land and (0.2%) is water. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
