Lewis & Clark

The Lewis & Clark Expedition Theme Study, undertaken in 1958, looks at and examines the significant sites and places that represent the western journey of discovery by explorers Meriwether Lewis and William Clark. The Lewis and Clark Expedition made significant contributions in the realms of geography, botany, wildlife, and geology, among others. A sub-theme within the larger and broader thematic framework of Advance of the Frontier, 1763-1830, this study acknowledges the sites which reflect most aptly the journey that Lewis & Clark undertook nearly two hundred years ago.
