Black Tooth Mountain

Black Tooth Mountain reaches 13,009 feet (3,964 meters) in the Bighorn Mountain Range and features steep slopes with a dark, jagged ridge line. The peak rises from rocky terrain and displays several small glaciers on its northern faces.

The first documented ascent took place in 1933 when a team of five climbers led by W. B. Willcox reached the summit. This early expedition established a route that later visitors would follow into the Bighorn high country.

The mountain sits within Cloud Peak Wilderness Area, representing the untamed high country that draws climbers and hikers to this remote region. The stark, rocky terrain shapes how visitors experience the solitude of the American backcountry.

Access is via the Little Goose Trail with about a 14-mile approach from the trailhead on Forest Road 26 west of Big Horn. The route is demanding and requires solid fitness and experience with high-altitude hiking.

The small glaciers clinging to the northern slopes create a geological feature that sets this peak apart from most others in the Bighorn range. These ice formations stand out sharply against the otherwise dry and rocky terrain surrounding them.
