This ecoregion lies almost wholly within Alberta but hugs the Alberta-British Columbia border from Banff northward to Jasper and Kakwa.

Mean annual temperature in the Eastern Continental Ranges is 2.5°C, mean summer temperature is 12°C and mean winter temperature is -7.5°C. Precipitation increases from east to west with elevation, from 600-800mm per year. Valley regions are marked by warm, dry summers and mild, snowy winters, and subalpine areas have cool, showery summers and cold, snowy winters (ESWG 1995).

This region covers the Rocky Mountains of Alberta, incorporating the eastern flanks of the Continental Ranges. The major peaks cluster around the Columbia Icefield, the largest ice field in the Rocky Mountains. The ranges themselves are linear with great cliffs and precipitous faces of thick sections of gray carbonate strata, and peaked by rock outcrops (ESWG 1995).
