The Boar's Tusk stands at 7100 feet elevation, 400 feet above the surrounding Killpecker Creek plain. Boar's Tusk is a dormant volcanic structure composed of lamporite material that dates back to 2.5 million years ago. Used as a landmark for Indigenous peoples, pioneers, hikers, railroad travelers, and countless other groups, this distinct feature is the core of a long dormant volcanic eruption.
Visit the site with respect. Boar’s Tusk plays an important role in the cultures of the Indigenous peoples who have called this land home for thousands of years. These peoples are known today as Shoshone, Arapaho, Ute, Shoshone Bannock, Lakota, Cheyenne, and Apsáalooké (Crow) tribes.
Climbing on the Boar's Tusk is NOT allowed.
A high-clearance vehicle is recommended for the access road.
