Preserving Campbell County history. Supporting its future.

The Rockpile Museum Association is a nonprofit organization dedicated to supporting the Campbell County Rockpile Museum and helping preserve, share, and celebrate the history of Campbell County and the Powder River Basin.
Through memberships, donations, fundraising, volunteer support, community partnerships, and special projects, the Association helps provide resources that strengthen the Museum and expand opportunities for people to connect with our local history.
What We Do
The Rockpile Museum Association works alongside the Rockpile Museum to support:
- Museum exhibits and educational programming
- Preservation of local history and collections
- Special projects and community events
- Outreach and opportunities to engage with Campbell County history
- Fundraising for programs, exhibits, and future Museum needs
- Travel and experiences that connect participants with history beyond our community
From longtime traditions to new projects like the Parade of Pronghorns, the Association brings together members, donors, volunteers, businesses, artists, and community partners who believe our history is worth preserving.
Supporting the Rockpile Museum
The Rockpile Museum is operated by Campbell County, while the Rockpile Museum Association is a separate nonprofit organization created to support the Museum and its mission.
That partnership allows the Association to raise private funds, build community support, and invest in projects and opportunities that enhance the Museum’s work.

You don’t have to be a historian to help preserve history.
Whether you become a member, make a donation, volunteer, attend an event, travel with us, or simply help share the stories of Campbell County, you are helping ensure our history remains accessible for generations to come.
