Welcome to Friends of Pompeys Pillar

We invite you to take a journey through our website to explore and learn more about the history of Pompeys Pillar National Monument.

We are a 501(c)(3) non-profit established in 1989 to support Pompeys Pillar National Monument, which contains the last physical evidence of the Lewis and Clark Expedition of 1803-1806. Our mission is to preserve and protect the monument by educating visitors through interpretation, special projects, and support the Bureau of Land Management (BLM) in its management of the site. The efforts of the Friends group was a driving force to get the site into the public lands domain, which resulted in the purchase of the historical land from the Foote family by the BLM in 1991. By working cooperatively with the BLM in the planning and administration of the site, the Friends group successfully accomplishes this mission.

We look forward to your visit!
