Description

Pompeys Pillar is a rock outcropping that rises 200 feet above the Yellowstone River 30 miles east of Billings. Pompeys Pillar is like a sandstone history book that reads like a who's who of western frontier history. Look on the rock face for the remains of animal drawings created by people who used the area for rendezvous, campsites, and hunting. In 1806 Captain William Clark carved his signature and the date in this rock. It is the only site on the trail where visible evidence of the Lewis and Clark Expedition may be viewed by the public.

Interpretive tours are available.

Admittance Rate: $3.00/vehicle Starting Memorial Day weekend and ending at the end of September.
