Lake Francis Case borders the eastern edge of this Lyman County landscape, where the Missouri River valley transitions into the dissected uplands of the Great Plains. The interior is defined by a dense network of intermittent drainages, including Short Cr, De Smet Cr, and the N Fork American Crow Cr, which carve deep draws through the prairie. Rising above these drainages is Lewis Hill, a prominent topographic landmark in a region primarily used for ranching and grazing.
