2015 Map of Gregory SE

About this map

Ponca Cr and Murphy Cr drain the rolling plains of southern South Dakota in this 2015 U.S. Geological Survey representation of Gregory County. The landscape is defined by the Public Land Survey System's rigid grid, where roads like 296th St and 341st Ave follow township lines through t96n r72w and t95n r71w. This section of the Milk's Camp Segment reveals a highly organized agricultural and range environment, punctuated by water features such as Star Lake and the winding course of Blue Eyes Cr. The map captures the enduring rural character of the Great Plains, illustrating how the late-nineteenth-century township-and-range survey continues to dictate modern infrastructure and movement across the land.
