Rattlesnake Cliffs
Montana

|
Location: Beaverhead County, on both banks of the
Beaverhead River, along I-15 (U.S. 91), about 10 miles southwest of
Dillon adjacent to the hamlet of Barretts.

On August 10, 1805, Lewis and three companions,
heading overland to seek the Shoshonis, stopped at and named these
cliffs because of the large number of rattlers in the vicinity. Five
days later, Clark's boat party passed by. On the return from the Pacific
in 1806, the Clark element went by the cliffs. Today they are known
locally as Beaverhead Rock. In 1963, as part of the Clark Canyon
Reclamation Project, a diversion dam was built in the river along the
cliffs. Most of the land in the immediate vicinity is federally
owned.
