Lewis and Clark Trail Heritage Foundation [MT]
The Lewis and Clark Trail Heritage Foundation seeks to preserve and share the history of the Lewis and Clark Expedition (1803-1806) and the physical sites thereof. To this end, the headquarters hosts the non-circulating William P. Sherman Library and Archives.
The foundation offers research library access, educator training, and research assistance. Appointments are required for library access. The website offers a curriculum guide for purchase, a video, and children's games and activities.
