Lewis and Clark National Forest anchors the southwestern landscape of this 1961 survey, where the terrain shifts from the high ridges of Connors Reef and Harrison Basin Ridge down toward the managed waters of the plains. The region is defined by a sophisticated network of early irrigation, including the Mosher Ditch, Carmichael Ditch, and Cuniff Ditch, which supported a cluster of established family operations such as the White Ranch, Nett Ranch, and Bean Ranch.
