The Sun River winds through the southern edge of this landscape, marking the border between Teton and Lewis and Clark Counties. This region is defined by an extensive network of irrigation infrastructure essential to High Plains agriculture, including the Spring Valley Canal, the Sun River Slope Canal, and the Floweree Canal. These man-made waterways cut across a terrain naturally sculpted by numerous coulees, such as Big Coulee and Silve Coulee.
