About this map

Lake Oahe dominates the northern reaches of this landscape, where the Missouri River valley meets the high plains of South Dakota. The boundary between Dewey and Stanley Counties cuts through the water and across the high plateaus, marking a transition in this rural ranching country. High, level benches above the drainage systems are identified as Kid Rich Flats, Marion Flats, and Mississippi Flats, providing rare stretches of flat ground amidst the deeply dissected coulees and breaks that feed into Foster Cr. Local history is preserved in small, remote sites such as Walking Horse Cem and Lindsay Cem, which stand as landmarks of early settlement and tribal heritage. Access to these areas is limited to primitive routes like Foster Bay Rd and Mule Deer Rd, reflecting the sparse population and preserved character of this riverine environment.
