2012 Map of Patch Skin Buttes SW

About this map

Lake Oahe dominates the southern landscape of this Dewey County region, where the Missouri River's backed-up waters reach into the prairie via Scatter Butte Cr and Stove Cr. The terrain is defined by the high ground of Gray Butte, situated in a relatively open expanse of the Cheyenne River Reservation. Settlement is concentrated at Marksville, positioned near the intersection of several regional routes, including BIA Hwy 8. The map illustrates the contemporary relationship between modern highway infrastructure and the intricate, flooded shoreline created by the Oahe Dam project downstream. This geography reflects a transition from traditional upland grazing and ranching toward the recreation and water management systems that now characterize this part of South Dakota.
