1952 Map of Hays Park

About this map

Wind River Indian Reservation and Shoshone National Forest meet at a rugged high-altitude boundary in this early 1950s survey. The landscape is defined by massive geographic features like Sacagawea Ridge and Dinwoody Ridge, which overlook the glacial waters of Upper Dinwoody Lake and Mud Lake. This area was mapped as part of a Department of the Interior program for the development of the Missouri River Basin, documenting a remote wilderness accessible primarily by the Dinwoody Trail and Gannett Road.
