1967 Map of Deep Creek SW

About this map

The high elevation drainages of the Big Horn Mountains define this mid-century survey of the Crow Indian Reservation. The landscape is dominated by a complex network of seasonal and perennial water sources, including Middle Creek in the north and the upper reaches of East Pryor Creek to the south. A notable geomorphic feature, simply labeled Crater, sits adjacent to Crater Lake, providing a distinct landmark in a region otherwise characterized by steep contour gradients and narrow canyons. Human presence is limited to an unimproved Jeep Trail that navigates the high ridges between Lost Creek and the surrounding draws. The map serves as a record of the area's hydrology before later climate shifts or land use changes, meticulously documenting numerous unnamed Springs and the vital Lost Creek Spring that sustained life in this arid upland terrain.
