About this map

Thebes and Sun Coulee anchor this high-plains landscape in Rosebud County, where the topography is defined by the complex drainage systems of the Missouri River watershed. The geography is characterized by the winding paths of Big Porcupine Cr and W Blacktail Cr, which carve through the dry terrain alongside features like Blind Coulee. These watercourses provided the essential structure for early cattle ranching and homesteading in this part of Montana.

Transportation through this open range relies on a network of established gravel routes, including Cohagen Rd and Petroleum Rd. Near the western edge, Thebes Lake sits as a notable hydrological feature in an otherwise arid environment. The map captures the organized layout of the Public Land Survey System, specifically t10n r36e and t9n r36e, which reflects the systematic division of the American West for settlement and resource management.
