Steep elevation changes are found in the Simpson Park Range, particularly the Buck Mountain, Shagnasty Mountain and Bates Mountain regions. The remainder of the unit exhibits gentle slopes, rolling hills, shallow and deep swales, benches and flats. Limited and scattered natural and artificial water sources can be found in the unit.

Sagebrush dominates most of the area. Some regions of the Simpson Park Range are densely inhabited by pinyon and juniper stands. Most of the ridges are covered in mountain mahogany above 7,500 feet, and many of the drainage have aspens at similar elevations. Areas at elevations of 6,000 feet and lower are made up of sagebrush with intermittent stands of fourwing saltbush and greasewood.

Alternative public roads are available that allow hunters to get through and around most of private areas. Much of the unit is publicly accessible by vehicle. Some areas are only accessible by hikers. The Grass Valley Roads provide the best access to the western parts of the unit, while the 3 Bars Road provides the best access to the eastern parts of the unit. US Highway 50 provides the best access to the southern reaches of the unit and the JD Ranch Road provide the best access to the northern reaches of the unit. Various primitive roads that stem from each of these primary routes provide better and more direct access into specific parts of the unit. Roadless areas on public land can be reached by hikers.
