Due to the steepness of the terrain, the areal extent of the Absaroka Volcanic Subalpine Zone is limited compared to subalpine areas in the sedimentary and granitic substrate mountains (Ecoregions 17k and 17ap). Like other subalpine regions in the Middle Rockies, subalpine fir, Englemann spruce, and limber pine are the dominant tree species. The highly dissected landscape is a result of erosion as these mountains are composed of loosely consolidated volcanic material. Soils are derived from a mixture of ash, tuff, basalt, and pumice. Sagebrush and grass grow in these droughty soils on open ridge tops where high wind and drifting snow limit tree growth. Mule deer, elk, bighorn sheep, and, on the eastern slopes, pronghorn antelope graze the high mountain meadows.
