2012 Map of Groton SW

About this map

The low-lying plains of Brown County are defined by a strictly surveyed grid of section-line roads and the wandering paths of prairie waterways. Meandering through the northern portion of this landscape, Mud Cr provides the primary drainage, eventually shifting southward to cut across the central section of the map. This 2012 survey illustrates the agricultural persistence of the region, where gravel and soil roads like 403rd Ave and 399th Ave bound expansive fields. In the southern half, the seasonal channel of Dry Run snakes through the terrain, intersecting the grid at 147th St. The absence of dense town clusters highlights the rural character of this part of South Dakota, where the economy remains tied to the land and the intermittent water sources that sustain it.
