Long Butte stands as a prominent landmark on this western Montana landscape, situated along the boundary between Lewis and Clark and Cascade counties. The terrain is defined by a sophisticated network of irrigation infrastructure, including the Knudson Ditch, Hamilton Ditch, Garino Ditch, and Hultine Ditch, which redirect water from natural courses like Willow Creek and Flat Creek. This reliance on managed water systems suggests a ranching and agricultural economy that has long adapted to the semi-arid environment east of the Continental Divide.
