Petticoat Peak Wilderness Study Area


In the Bannock and Caribou Counties, within a mile of the beautiful city of Lava Hot Springs, Idaho, the BLM manages 11,298-acres of wilderness terrain that make up the Petticoat Peak Wilderness Study Area. With its highest point, Petticoat Peak, at 8,000 feet, the wilderness study area is situated within the Fish Creek Mountain Range and has a topography that is steep, rugged, and mountainous.

From any spot, one can look out to ridges, canyons, and mountain peaks protruding to the skies. While rocky and rugged, the wilderness study area isn’t barren or sandy. It’s covered with green vegetation of juniper, sagebrush, and mountain shrubs. The thick woodland of Douglas-fir mingled with limber pine and lodgepole makes the wilderness study area even more verdant in its east corner, while the west slopes are adorned with aspen groves.

Bannock County also holds a historic position for being the site of important Indian trails, overland trails, and trapper trails. Even today, it holds within its boundaries important state line routes, interstate highways, and railroads. This makes Petticoat Peak Wilderness Study Area a rare wilderness region that is still close to road networks and amenities yet offers the semblance of solitude and seclusion.

The trail that you might end up crossing at Petticoat Peak Wilderness Study Area could be the very same one that Northern Shoshone and Bannock tribal groups took hundreds of years ago!
