2021 Map of Lacy

About this map

Lacy sits atop the high ground of Stanley County in this contemporary study of South Dakota's river-cut landscape. The map highlights the significant drainage systems feeding into the Missouri River, which forms part of Lake Oahe in the northeastern corner of the sheet. The terrain is characterized by a series of prominent ridges and erosional features, most notably Anderson Ridge, which is flanked by numerous named draws including Huckfeldt Draw, Casey Draw, and True Draw. These landforms dictate the local road network, with routes like Mission Ridge Rd and Sansarc Rd traversing the higher elevations. The intricate network of seasonal waterways, such as Willow Cr and Ash Cr, illustrates the hydrological patterns typical of the region's semi-arid environment, providing a detailed record of the physical geography near the river's edge.
