About this map

Carlock serves as the central point for this Gregory County landscape, where the agricultural grid meets the drainage network of the Missouri River plateau. The area is defined by a series of intermittent watercourses, including Murphy Cr and Indian Cr, which carve subtle valleys through the prairie. These natural features dictated the placement of the early road network, seen here in the transition between named avenues like 334th Ave and numbered county roads.

Genealogists and local historians will find the placement of the Peace Cem and Congregational Cem particularly significant, as these sites often mark the locations of early community centers or vanished church congregations. The map detail reflects the persistence of the Public Land Survey System, with township and range lines such as t96n r73w providing a reliable framework for tracing historical land patents and family farmsteads in southern South Dakota.
