About this map

Chimney Butte rises above the high plains of Perkins County, anchoring a landscape defined by the drainage networks of several ephemeral streams. This modern survey illustrates the persistent rural character of northwestern South Dakota, where the Public Land Survey System continues to dictate the orientation of local infrastructure like Prairie City Rd and 134th St.

The hydrology of the region is centered on Rabbit Cr, which meanders through the central and southern portions of the quadrangle. Other watercourses, including Bog Cr, Gap Cr, and Peggy Cr, indicate the subtle shifts in elevation that have shaped ranching and movement through this part of the state. To the north, the terrain is further distinguished by Mallory Draw, a landform that highlights the natural erosion patterns of the western Dakota prairie.
