1971 Map of Selfridge SE

About this map

The Porcupine Hills dominate the western horizon of this Sioux County landscape, which was documented during the early 1970s as part of a federal development program for the Missouri River Basin. The terrain is defined by a complex network of drainages and high ridges, where the seasonal flow of Fourmile Creek cuts through the prairie toward the Missouri River. A small, isolated cemetery known as Gayton Cem is the primary evidence of human settlement on this portion of the Standing Rock Indian Reservation, offering a specific point of interest for genealogists researching early regional burials. The map's sparse labels reflect a vast, open rangeland where section lines and unimproved trails provide the only grid for navigation across the dissected topography.
