Location
The ecoregion consists of a long chain of high rocky mountains in the interior of Alaska , stretching north from the base of the Alaskan peninsula, turning east along the Alaskan ridge and south along the Wrangel and St. Elijah mountains in eastern Alaska to the Canadian border and Yakutat Bay . In Canada, the ecoregion includes the southwest corner of the Yukon Territory and the northwest corner of British Columbia . These mountains are mostly constantly covered with ice and snow from a level of 2150 m and are separated by valleys filled with ice fields and large glaciers . Several foci are free of ice and represent a rocky, rocky and alpine tundra . The height of the mountain range increases from sea level (on the west coast) to 600 m in the valleys and 4000 m at the peaks. Denali is located in the region, the highest peak of North America at 6,100 m, as well as the mountains of St. Ilya and some of the highest peaks of Canada reaching 6,000 m. The region is separated from the coast by the tundra and ice fields of the mountains of the Pacific coast , so the climate there is continental. Rainfall ranges from 200 mm per year on high slopes to 400 mm per year in low areas.
