Beaverhead Rock stands as the primary landmark in this river valley landscape where the Beaverhead River and Big Hole River converge. The terrain is defined by an intricate network of water management features, including the California Slough, Baker Slough, and Schoolhouse Slough, alongside numerous man-made channels like Mule Shoe Ditch and Island Ditch. This system of ditches and sloughs reflects a long-standing agricultural dependence on the river basin’s flow.
