2015 Map of Crokett Mountains

About this map

Lake Oahe dominates the northwestern corner of this territory, where the Missouri River waters meet the edge of Dewey and Stanley Counties. The landscape is defined by the sharp verticality of the Crockett Mountains and several prominent navigational landmarks including Lindsay Butte, Black Butte, and Cedar Butte. This 2015 survey reveals a terrain deeply etched by drainage systems, primarily the Minneconjou Creek and its branches, the West Fork and East Fork. The map illustrates the sparse infrastructure typical of this part of South Dakota, showing only isolated rural corridors like 262nd Avenue and Link Road connecting the scattered ranch lands. The extensive network of seasonal streams, such as Sansarc Creek, highlights the complex hydrology required to sustain life and livestock in this high-plains environment.
