2015 Map of Corona

About this map

Corona serves as the primary hub of this eastern South Dakota landscape, positioned near the intersection of Cr-11 and Main St. The town's layout follows a traditional grid, surrounded by a vast section-line road network including 139th St and 471st Ave. This 2015 survey illustrates the enduring agricultural character of the region, where the Roberts Co and Grant Co line divides the territory. The topography is defined by the wandering path of the N Fork Whetstone River, which cuts through the northern sections of the map. This river system creates a distinct break in the otherwise regular terrestrial survey lines, providing the primary natural drainage for the surrounding prairie farmsteads.
