About this map

Glad Valley sits at the intersection of several historic administrative boundaries in Ziebach and Corson counties. This early 1980s provisional survey documents the rural character of the northern South Dakota plains where the Grand River National Grassland, Standing Rock Indian Reservation, and the Cheyenne River Indian Reservation Boundary converge. The landscape is defined by the drainage of the East Fork Twin Butte Creek and the West Fork, which feed into the Glad Valley Dam.

Genealogists and local historians can locate specific sites of interest such as the Cem and a Gravel Pit, which reflect the small-scale infrastructure and community hubs of this isolated region. The prominent Twin Butte serves as a significant natural landmark for navigating the high plains. The map's layout highlights the section lines and township boundaries that dictated the settlement patterns of this vast prairie.
