Trapper Creek Wsa

Bureau of Land Management, Wyoming.

The Trapper Creek WSA encompasses 7,200 acres of BLM-administered public land with no private or state inholdings. Trapper Creek is one of the most spectacular canyons on the west slope of the Bighorns. It is characterized by the dramatic vertical relief of the cliffs, spires and massive rock outcrops of the canyon walls, the presence of a clear cascading stream and the rich color combinations. It 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 (Great X) is located in the WSA. The elevation difference between the lower and upper entrances is 1,403 feet, making Great X the third-deepest cave in the United States. The Trapper Creek unit provides outstanding opportunities for primitive and unconfined recreation. These activities could include hiking, spelunking, mountain climbing, hunting, fishing and other activities such as photography, nature study and wildlife observation.
