Eco Region Assessment 8. Elias Range ecoregion forms a large crescent in southern Alaska, beginning at the base of the Alaska Peninsula and ending at the northwest extreme of British Columbia. The ecoregion shares boundaries with eight other ecoregions, as well as the northeastern shore of the Cook Inlet, and consists of areas in Alaska, the Yukon, and British Columbia. Extensive icefields and glacial systems are prevalent, especially at higher elevations, and provide the source for numerous sediment laden streams.
Permafrost occurs sporadically throughout the ecoregion.
Climate in the ecoregion is largely affected by elevation. Killing frosts may occur at any time of the year. Although wildfires rarely occur, snow avalanches cause fairly frequent disturbances.
