2017 Map of Seneca NW

About this map

Potter County and the adjacent borders of Walworth and Edmunds counties are captured here in a landscape defined by prairie potholes and township grids. The terrain is characterized by numerous small depressions and basins, most notably Alkali Lake in the northeastern corner. Settlement in this portion of South Dakota is sparse, oriented around a network of section-line roads like Co Rd 954 and Co Rd 820. For local historians and genealogists, the presence of Advent Cem near the center of the sheet and Spring Cem to the south provides specific points of interest for tracing early family roots and community markers in a predominantly agricultural region.
