The 119,790-acre Lost Creek Wilderness runs through this unit, providing a contrast between Denver, less than 50 miles to the northeast and pristine backcountry that supports many elk and mule deer. The 138,000-acre-wide Hayman Fire in 2002 burned much of the Pike National Forest that opened up thousands of acres.

Several Mountain ranges make up the higher elevations of this unit, Tarryall, Kenosha and Platte River. They traverse tree-lined mountain parks, fascinating rounded granite domes, rare granite arches a number of creeks and long canyons.
