About this map

Minnetonka Valley and Survey Valley define the rhythmic, dune-like landscape of this Sheridan County region just after World War II. The map reveals a highly decentralized rural community, anchored not by a town center but by a network of one-room schoolhouses such as School No 112, School No 127, and the paired North Sch No 165 and South Sch No 165.

Water is the primary organizing force for settlement here, with Spring Lake Camp in the northeast and a string of namesake basins including Twin Lakes, Cravath Lake, and Diamond Lake providing essential resources. The presence of numerous windmills and a network of firebreaks suggests a landscape dedicated to large-scale ranching and careful resource management in a semi-arid environment. This 1948 survey captures the intricate topographical details of the Nebraska Sandhills before later developments altered the local water table and grazing patterns.
