Clark Days 2016

Clark Days 2016 will be held on July 30, 2016. Free camping on Friday night and the night of the event.

Admission is free for this event. Donations from the public help make events like this possible. Please donate to help us continue to make this event possible.


Clark Days are held at Pompeys Pillar each year on either the last weekend of July or the first weekend of August. In 2015, Clark Days will be held on the 209th anniversary of Clark’s visit to Pompeys Pillar, July 25th. The event commemorates William Clark’s stop at the site on his trip down the Yellowstone River. Activities include interpretive programs, demonstrations, nature walks, and a main presentation. The Saturday night of Clark Days is the only night of the year when overnight camping is allowed at the Pillar. The Bureau of Land Management has park rangers on duty at the visitor center to assist campers.



Clark Days is sponsored jointly by the Bureau of Land Management and the Friends of Pompeys Pillar. Daily admission fees apply.
