1986 Map of Timber Lake

About this map

The Moreau River and Grand River systems define this mid-1980s landscape across the Cheyenne River and Standing Rock Indian Reservations. This survey captures a region where the vast Grand River National Grassland meets a network of ranching and farming communities connected by a developing road infrastructure. Settlements such as Isabel, Timber Lake, and Eagle Butte serve as the primary hubs, while smaller locales like Glad Valley and Firesteel are situated near vital water resources such as Isabel Lake and Firesteel Creek. The map documents the industrial presence of Strip Mines and several small airstrips, including the McDaniel Landing Strip and Hunt Landing Strip, which reflect the remote transportation needs of north-central South Dakota. Significant conservation areas like the Little Moreau State Recreation Area contrast with the flat, expansive terrain of Pleasant Ridge and the Fairview plateau, illustrating the balance between public land management and agricultural life.
