The Alaska Range is a relatively narrow, 400-mile-long (650 km) mountain range in the southcentral region of the U.S. state of Alaska, from Lake Clark at its southwest end[1] 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.

The range forms a generally east–west arc with its northernmost part in the center, and from there trending southwest towards the Alaska Peninsula and the Aleutian Islands, and trending southeast into British Columbia and the Pacific Coast Ranges. The mountains act as a high barrier to the flow of moist air from the Gulf of Alaska northwards, and thus have some of the harshest weather in the world. The heavy snowfall also contributes to a number of large glaciers, including the Cantwell, Castner, Black Rapids, Susitna, Yanert, Muldrow, Eldridge, Ruth, Tokositna, and Kahiltna Glaciers. Four major rivers cross the Alaska Range, including the Delta and Nenana Rivers in the center of the range and the Nabesna and to the east.

The range is part of the Pacific Ring of Fire, and the Denali Fault that runs along its southern edge is responsible for many major earthquakes. Mount Spurr is a stratovolcano located at the northeastern end of the Aleutian Volcanic Arc which has two vents, the summit and nearby Crater Peak.
Parts of the Alaska Range are protected within Wrangell-St. Elias National Park and Preserve, Denali National Park and Preserve, and Lake Clark National Park and Preserve. The George Parks Highway from Anchorage to Fairbanks, the Richardson Highway from Valdez to Fairbanks, and the Tok Cut-Off from Gulkana Junction to Tok, Alaska pass through low parts of the range. The Alaska Pipeline parallels the Richardson Highway.
Naming history[]
The name "Alaskan Range" appears to have been first applied to these mountains in 1869 by naturalist W. H. Dall. The name eventually became "Alaska Range" through local use. In 1849 applied the name "Tschigmit" to this mountain range. A map made by the General Land Office in 1869 calls the southwestern part of the Alaska Range the "Chigmit Mountains" and the northeastern part the "Beaver Mountains".[2] However, the Chigmit Mountains are now considered part of the Aleutian Range.

- ^ Jump up to: a b Sources differ as to the exact delineation of the Alaska Range. The Board on Geographic Names entry 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.
