The Sun River winds through the southern reaches of this landscape, defining a valley where the small settlements of Lowry and Simms sit at the intersection of Teton, Cascade, and Lewis and Clark counties. The terrain is characterized by a sophisticated irrigation network, where the Greenfields Main Canal and Spring Valley Canal contrast with the natural drainage of the Big Coulee and Floweree Coulee.
