1950 Map of Interior

About this map

Interior sits at the northern edge of the Pine Ridge Indian Reservation, where the prairie landscape transitions into the sharp breaks of the Badlands National Monument. This 1950 field-checked survey reveals a critical junction between the Chicago Milwaukee St Paul and Pacific railroad and the winding course of the White River. The river forms a natural boundary between Jackson and Washabaugh counties, cutting a wide, light-yellow path across the center of the sheet. Further south, the high ground of Pine Ridge is dissected by seasonal drainages like Lost Dog Creek and Sixteenmile Creek. Near the southern edge, the isolated Lone Tree Sch. serves as a lone marker of educational infrastructure in this rural cattle-country landscape, while the Monument Hdqrs at the northern border anchors the early development of the national park lands.
