Army officials no longer consider this a trophy mule deer area, emphasizing that managers have allowed an overharvest as researchers study several ways to control chronic wasting disease.

The unit has flat plains crossed by arroyos that drain into the Purgatoire River by many deep canyons. A number of steep plateaus and rugged ridges complete the landscape.

Shortgrass prairie consisting of buffalo and blue grama grasses, areas of pinyon/juniper, sagebrush, yucca, bitterbrush, Russian thistle and cottonwoods.
