2021 Map of No Heart Creek

About this map

No Heart Butte stands as the central landmark in this portion of Dewey County, overlooking a landscape defined by its complex drainage systems and the expansive waters of Lake Oahe. The map illustrates the rugged topography of the Cheyenne River Reservation, where the Missouri River forms the southern boundary. Numerous named waterways, including No Heart Cr, Tall Prairie Chicken Cr, and Little Willow Cr, carve deep coulees through the high plains. While modern routes like Bia Hwy 8 and Bia Rd 8 provide contemporary access, the map primarily documents the natural landforms and the scale of the reservoir. This detailed survey captures the intersection of the prairie landscape with the hydraulic engineering of the Missouri River, showing the vast reach of the reservoir into the surrounding drainages like Charlie Cr.
