The WSA provides opportunities for experiencing naturalness, solitude, and primitive and unconfined recreation. The WSA is an area of rugged topography characterized by deep, steep-sided drainages flowing toward the Bighorn River. Cedar Mountain is the dominant feature of the unit. Petrified wood and reptilian fossils are found in the Lance and Meeteetse formations in the southern end of the WSA. Mammalian fossils are found in the Fort Union Formation north of Cedar Mountain.

Visitor Advisory

Access to wild lands inherently requires good navigational skills and four-wheel drive or high-clearance vehicles. Visitors should be prepared for adverse weather and road conditions. The WSAs in the BLM Field Office are primarily accessed by unnamed or unsigned two-track roads that in many cases may be difficult to find without sufficient navigational skills and equipment.

Wilderness Study Areas

WSAs are undeveloped federal lands that retain their primeval character and influence, without permanent improvements or human habitation, and are managed so as not to impair their suitability for preservation as wilderness. Backcountry recreation is a common use along with Leave no Trace Outdoor ethics. Please be advised these areas are restricted and do not allow for the use of motorized and mechanized equipment.
