Clark's Lookout State Park preserves the hill above Montana's Beaverhead River that William Clark climbed on August 13, 1805, during the Lewis and Clark Expedition. About a mile north of Dillon, the eight-acre park marks the high point where Clark took compass readings and sketched a map of the Beaverhead Valley, establishing the site's historical significance. Today, the small state park combines that connection to exploration history with public access, offering picnicking and the opportunity to climb to the overlook and view the valley from the same place Clark used.
