2015 Map of Slaughter Reservoir

About this map

The Belle Fourche River winds through this high-plains landscape where the borders of Wyoming and South Dakota meet. This 2015 survey documents the drainage patterns of the northern Black Hills foothills, centered on the Slaughter Reservoir and the prominent Norgrain Hill. The topography is defined by a dense network of seasonal watercourses, including Grummit Canyon Cr and the multiple forks of Hay Cr. Ranching infrastructure dominates the human geography, evidenced by local routes like Dobesh Ranch Rd and Olson Rd. The map provides a precise look at the land division and access roads in this sparsely populated cattle country, from Mona Rd in the west to Upper Redwater Rd in the southeast corner.
