Alaska’s similarities with Appalachia and the Ozarks

The predominant mountains in Alaska are the Alaska Range. They have some similarities with Appalachians. For example, the length of Appalachian mountain is 480 km and the length of Alaska Range is 650 km. The highest is mount Denali from Alaska Range, which is actually the highest from the entire USA. Both mountains were barriers in the past, but for two different aspects. The Appalachians were barriers for human expansion while the Alaska Range is a barrier for moist air from NW of Gulf of Alaska.

The highest mountain from Alaska Range is Mount Denali or Mount McKinley. This mountain is made out (mostly) from granitic pluton and has been uplifted by tectonic pressure. The move of tectonic plates raised the altitude of the mountain but the erosion of the sedimentary rock stripped away some of it.

Also, there is a weather station near the summit of Denali. This belonged to a Japanese alpine club and was donated to the international Arctic Research Center.

If you are visiting Alaska Range, you can enjoy the view of these beautiful places from different location. If you are in the NW of mount Denali, you can spend the night at “Eureka Lodge”.



And don't forget: In Alaska Range it is pretty cold, so make sure you have thick clothes.
