About this map

Fort Peck Lake dominates this landscape, where the waters of the Missouri River reservoir reach into the complex drainages of Valley and Garfield counties. The terrain is defined by a dense network of coulees that carve through the high ground, creating a labyrinth of ridges and inlets. Notable among these are Bighorn Coulee, Rattlesnake Coulee, and Coyote Coulee, which draw down toward the expansive lake surface.

Elevated features such as Harper Ridge and the prominent Peterson Point overlook the shoreline, providing distinct landmarks within this transition between prairie and water. The map traces the varied arms of the lake, including Sutherland Creek Bay in the north and the northern edge of Hell Creek Bay to the southeast. This geography reflects the post-dam environment of the mid-20th century, where traditional ranching uplands met the rising waters of one of the nation's largest man-made reservoirs.
