About this map

The boundary between Tripp Co and Gregory Co cuts vertically through this rural landscape in south-central South Dakota. The terrain is defined by the drainage network of the Bull Creek system, including the meandering paths of W Br Bull Cr, Bull Cr, and E Br Bull Cr. This 2017 survey illustrates the persistent township and range grid that governs the region's organization, with section lines marked by a network of gravel and local roads such as Viaduct Rd and 332nd Ave. The map reflects a classic Great Plains agricultural pattern, where infrequent watercourses provide the primary natural breaks in an otherwise structured landscape of section-line roads and wide-open acreage. Researchers can observe how modern county roads like Co Rd 3 continue to follow these historical survey lines.
