1952 Map of Hays Park

About this map

Wind River Indian Reservation and the Shoshone National Forest meet in this 1952 study of high-altitude topography. The map illustrates a landscape of significant relief, where the Reservation Boundary follows the divide of the Sacagawea Ridge and Dinwoody Ridge. The drainage system is central to the area's character, featuring Upper Dinwoody Lake and Mud Lake, with water moving through Dinwoody Creek toward a geological Natural Bridge. The survey details the high-country access provided by the Dinwoody Trail, crossing through Hays Park near Relic Creek. Evidence of high-altitude life includes Cold Springs and the sheltered Hidden Valley, providing a record of this wilderness before contemporary developments in the Missouri River Basin.
