2015 Map of Miller Dam

About this map

Marple Butte stands as a prominent landmark in this segment of the West River prairie near the border of Ziebach and Dewey counties. The landscape is defined by the drainages of Little Bear Cr and Cottonwood Cr, which carve through the open range toward the eponymous Miller Dam. This area reflects the sparse settlement patterns typical of the Cheyenne River Reservation region, where small community hubs like Chase are connected by a grid of rural routes such as Cherry Creek Rd and Olsen Ave. The map illustrates a high-plains environment where water management and topography dictate the placement of ranching infrastructure and remote dwellings across the T11N and T12N R21E townships.
