1973 Map of Iron Post Buttes SW

USGS Topo · Published 1976

About this map

Lake Oahe dominates the eastern edge of this Stanley County landscape, following the course of the Missouri River as it serves as an Indefinite Boundary between Stanley and Sully counties. The western uplands are defined by deep drainage basins including Deep Creek, Snake Creek, and Chantier Creek, which cut through the high plains toward the reservoir. A significant historical marker, the Old Indian Treaty Boundary, traverses the northern portion of the sheet, providing a spatial record of nineteenth-century land agreements. For aviation history and transportation research, the Thompson Landing Field stands out as a localized landmark in this sparsely populated stretch of South Dakota. The topography here reflects the post-dam era of the mid-twentieth century, with underwater contours in the lake based on data from 1947, prior to the full inundation of the river valley.
