This ecoregion occupies a transitional region of mountains, valleys, and high plateaus between the Coast and Saint Elias Mountains to the west, and the Northern Rocky Mountains to the east.
This ecoregion has a predominantly subarctic climate (Köppen Dfc ) with cool summers and cold winters. Mean annual precipitation is approximately 350-600 mm, but increases up to 1000 mm at higher elevations. The highest elevations feature an alpine tundra climate.
The lower mountains and valleys are dominated by alpine fir, lodgepole pine, and black and white spruce all intermixed with a variety of deciduous shrubs. Higher elevations are dominated by dwarf birch, willow, and a variety of dwarf ericaceous shrubs. The highest elevations are dominated by grass, lichen, and moss.[2]
Fauna found throughout this ecoregion include grizzly bear, black bear, moose, mountain goat, beaver, red fox, wolves, ptarmigan, and snowy owl.[2]
