Friends of Pompeys Pillar is a volunteer‑driven nonprofit dedicated to preserving, protecting, and sharing the rich history of Pompeys Pillar National Monument. Through memberships, donations, and community events, we support educational programs, fund interpretive signage, provide transportation grants for school field trips, and help maintain the site for future generations. Our work ensures that the stories of Lewis and Clark, the legacy of Clark’s signature, and the cultural significance of the Pillar remain accessible, engaging, and alive for all who visit.
