About this map

Laundreaux Butte stands as a prominent landmark in this segment of the Missouri River plateau along the boundary of Corson and Dewey counties. The landscape is defined by the deep drainage patterns of several tributaries, including Le Beau Cr, Deadman Cr, and Laundreaux Cr, which flow toward the southeastern corner of the sheet. In this area, the waters of Lake Oahe mark the modern extent of the reservoir, a stark contrast to the historical dry creek beds that once carved through these high plains.

Transportation across this prairie terrain is limited to a network of rural routes such as Promise Rd and Co RD 11, which follow the section lines and natural contours of the land. The mapping of Township 17 North, Range 29 East and its neighbors reveals a sparsely populated landscape where the topography itself—defined by significant elevation changes around the eponymous butte—dictates the placement of the few existing roads. This 2021 survey provides a clear view of the complex hydrography feeding into the Missouri River system.
