2017 Map of Laundreaux Butte

About this map

Laundreaux Butte rises above the rolling grasslands of the Standing Rock and Cheyenne River reservation borderlands, overlooking a landscape defined by seasonal watercourses and the northern reaches of Lake Oahe. This 2017 survey shows the transition between Corson and Dewey counties, where the drainage patterns of Laundreaux Cr, Le Beau Cr, and Deadman Cr have shaped the prairie for generations. The road network is sparse, primarily composed of rural routes like Promise Rd and several county roads, reflecting the vast, open character of this ranching country. By mapping the exact contours of the drainages, including Claymore Cr and Tom Hill Cr, the document provides a precise look at the hydrology of the Missouri River plateau in the modern era.
