2015 Map of Powder River Pass

About this map

Bighorn National Forest defines this high-altitude landscape in Johnson County, where the southern Big Horn Mountains reach significant elevations at Loaf Mtn and Sheep Mtn. The hydrology of the area is complex, characterized by the headwaters of the N Fork Powder River and N Fork Crazy Woman Cr, which flow from glacial basins such as those containing Paradise Lake and Magdalene Lake. Transportation through this steep terrain is anchored by the crossing at Powder River Pass, with secondary access provided by Pole Creek Rd and the evocatively named Gold Mine Rd. This 2015 survey illustrates how modern infrastructure follows the natural corridors established by Munkres Pass and various creek drainages including E Tensleep Cr and Duck Cr, maintaining the historic routes used to traverse these Wyoming highlands.
