2017 Map of Presho NW

About this map

Fort Pierre National Grassland dominates the northern reaches of this Lyman County landscape, preserving the open character of the South Dakota prairie as it appeared in the 21st century. The terrain is defined by the winding drainages of Stony Butte Cr and Medicine Cr, which carve through the high plains. A grid of section roads, including 236th St and 243rd St, provides access to the agricultural interior. Historically significant transportation corridors traverse the southern half of the map, where the path of Old Hwy 16 runs parallel to modern transit routes. This survey highlights the geographic transition between protected federal grasslands and the private ranchlands that characterize the region's rural economy.
