2021 Map of Grandmas Butte

About this map

Grandmas Butte serves as a prominent landmark in this section of Perkins County, anchoring a landscape defined by rolling prairie and intermittent drainage systems. The hydrography of the region is dominated by Thunder Butte Creek, which flows across the southern portion of the quadrangle, while Murphy Cr and Snake Cr carve through the northern terrain. This area of South Dakota maintains a traditional township and range grid, evidenced by the prominent section lines and the network of section-line roads like Date Rd and 170th Ave. Elevation markers such as the Rocky Hills and Wolf Hill provide essential geographic context for this sparsely populated ranching country. The presence of Divide Rd along the western edge suggests a natural height of land separating local watersheds in the High Plains.
