2017 Map of Crystal Lake

About this map

Crystal Lake sits as the central geographic landmark in this Aurora County landscape, providing a natural focal point amidst a highly organized agricultural grid. The terrain is defined by the rectilinear section lines of t102n r65w and surrounding townships, which dictate the placement of local thoroughfares like 380th Ave and Co Rd 30. Bisecting the northern half of the quadrangle is Interstate 90, a major transportation corridor that cuts across the older section-line roads, illustrating the evolution of South Dakota's transit network from local farm-to-market paths to national expressway infrastructure. The map reveals a land heavily influenced by the Public Land Survey System, where modern county roads like Co Rd 44 and Co Rd 48 continue to trace the boundaries established by nineteenth-century surveyors.
