Values

The Trapper Creek WSA contains one of the most spectacular canyons on the west slope of the Bighorn Mountains. Dramatic vertical relief, massive canyon walls, red cliffs, a clear cascading stream, and vibrant riparian vegetation are found here. The WSA contains important habitat for rare and endangered species such as bald eagles and peregrine falcons and is crucial winter range for elk and deer. The lower entrance to Great Expectations Cave is located in the WSA. The elevation difference between the lower and upper entrances is 1,403 feet, making it the third-deepest cave in the United States.

From Shell, WY, turn south off Hwy 14 onto Trapper Creek Road (a Bighorn County road).  Drive 2.7 miles to County Road R43 (Black Mountain Road), turning  left at the “Y” and sign;  the pavement ends here.  In 0.5 miles take the left “Y” leaving the gravel at an “Entering Public Lands” sign.  Continue on R43 for 4.4 miles to the boundary of the WSA, which will be on the right side of the road for the next 1.5 miles.  

Visitor Advisory

The Black Mountain Road requires four-wheel drive and should not be driven when wet.   Visitors should be prepared for adverse weather and road conditions. Visiting the WSAs requires sufficient navigational skills and equipment.  The Spanish Point Karst Area of Critical Environmental Concern (ACEC) overlays the WSA and has been closed to motorized use.  Please abide by all posted regulations.

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.
