Upper Missouri River Breaks National Monument anchors the southern landscape of this Blaine County region, where the terrain breaks toward the Missouri River valley. The area is defined by a complex network of ephemeral drainages and coulees, including Jacks Coulee and its West Fork, which carve through the high plains. This contemporary mapping shows a vast, open landscape where water is a scarce and precious resource, centered on features like Lake Seventeen and the winding course of Rattlesnake Creek.
