2021 Map of Iron Post Buttes SW
USGS Topo · Published 2021About this map
Lake Oahe and the Missouri River dominate the eastern reaches of this Stanley County landscape, where the water's edge meets the dissected uplands of central South Dakota. The topography is defined by significant drainages including Snake Cr, Deep Cr, and Chantier Creek, which carve through the terrain toward the reservoir. The road network reflects the rural and ranching character of the region, anchored by Mission Ridge Rd and Agency Creek Rd. This survey illustrates the intricate relationship between the Missouri River's dammed water levels and the surrounding creek valleys, providing a precise record of the shoreline and elevation contours within t7n r28e and neighboring townships.
