The Divide Basin HMA encompasses nearly 779,000 acres, of which 562,702 acres are BLM-administered public lands. The management area is located 40 miles east of Rock Springs to the Rawlins/Rock Springs Field Office boundary, west to the Continental Divide, and north of Interstate 80 to just south of South Pass City.

The northern portion of the herd management area consists primarily of consolidated public lands with state school sections and small parcels of private land making up the remaining lands. The southern portion is in the checkerboard land ownership area created by the Union Pacific Railroad grant. Topography within the herd area is generally gently rolling hills and slopes with some tall buttes and streams. Elevations range roughly from 6,200 to 8,700 feet. Precipitation ranges 6-10 inches, predominately in the form of snow.

The AML for this HMA is 415-600 horses. Most horses are bay, sorrel, black, brown, paint, buckskin, or gray, but many colors and combinations are present. The Wyoming horses have a diverse background of many domestic horse breeds. They are most closely related to North American gaited breeds such as Rocky Mountain Horse, American Saddlebred, Standardbred, and Morgan. The horses range from 14 to 15.5 hands and weighs up to 1,100 pounds mature weight. Vegetation in the HMA is dominated by sagebrush and grass intermixed with greasewood and saltbrush. The area also supports significant wildlife populations including elk, deer, and antelope and domestic cattle and sheep utilize the area lightly in summer and moderately in winter.
