About this map

Wapiti Ridge and the high elevations of the Washakie Wilderness dominate this pocket of the Wyoming backcountry as it was recorded in 1991. The landscape is defined by the headwaters of several drainages, where Hardpan Creek and Yellow Creek descend from the ridges toward the north and east. The concentration of high-altitude landmarks, such as Ptarmigan Mountain and Citadel Mtn, highlights the difficult accessibility of the terrain within the Shoshone National Forest.

In the southeast corner, the small settlement of Ishawooa sits along the Shoshone River, marking a transition from the wilder uplands to the river valley. The map traces the winding paths of Ishawooa Creek and Bobcat Creek through the Ishawooa Hills, providing a clear record of the watershed before it reaches the main river. Remote water features like Hardpan Lake offer specific points of interest for researchers studying the land use and hydrology of this protected region.
