Twin Buttes WSA

Twin Buttes WSA.

Location: Sweetwater County

Nearest Town: Green River (28 miles)

BLM Acreage: 22,561 surface acres + 1,280 acres split estate

Recommended for Wilderness: 23,841 acres

Primitive & Unconfined Recreation:
These WSAs offers outstanding opportunities for primitive and unconfined recreation. Camping, rock hounding and hiking occur on an infrequent basis. Antelope and deer hunters utilize the area and there is some opportunity for hunting coyotes. Most off-road vehicle use has been related to hunting activities.

The Devils Playground/Twin Buttes WSAs encompass 22,561 acres of BLM-administered land and 1,280 acres of split estate. The WSAs are characterized by highly eroded badlands with scattered patches of sagebrush, grass and juniper. Black Mountain and the Twin Buttes are prominent topographic features in the area.

The WSAs are essentially natural in character, although they includes 23 seismic and two-track trails, 17 reservoirs and two fences. The seismic trails and two-track trails vary from faint and obscure to bladed scars and substantially unnoticeable roads.

The area is characterized by highly eroded badlands areas surrounding two large mesas of high relief. Elevation ranges from 6,200 feet in the northern washes of Devils Playground to 8,012 feet on the Twin Butte mesa.

Very little vegetation grows on the badlands, which comprises the vast majority of the WSAs. However, there are some pockets of sagebrush, saltbrush and juniper.

Devils Playground/Twin Buttes WSAs' topography and size combine to disperse use, providing ample opportunities to experience solitude. Present recreation use of the WSAs consist mainly of hunting activities and off-road vehicles traversing the area. Some overflow use from the Flaming Gorge National Recreation Area is occurring in the form of off-highway driving and sightseeing. This use may increase as the popularity of the Flaming Gorge area increases.

Special Features:
The area has interesting and unusual geologic features. Fossil deposits and evidence of early man can be found throughout the WSAs. Indians pursuing a nomadic hunter-gatherer lifestyle occupied the area continuously for 9,000 years. The Pine Springs archaeological site, a cultural ACEC, is adjacent to the WSAs. The southeast flanks of Black Mountain are covered by one of the most extensive (and significant) tipi ring sits in southwestern Wyoming. Existing cultural resource data supports the conclusion that these WSAs are a sensitive area of highly significant values.
