1967 Map of Powder River Pass

About this map

Powder River Pass serves as the central high-altitude crossing in this 1960s survey of the Johnson County high country. Located within the Bighorn National Forest, the terrain is defined by extreme elevations and the headwaters of numerous divergent drainage systems. Notable peaks such as Loaf Mountain and Hesse Mountain overlook a complex network of alpine water bodies, including Firehole Lakes, Paradise Lake, and Magdalene Lake. The map illustrates the early infrastructure of Route 16 as it winds through the pass, providing a crucial link across the Bighorn range. This topography highlights the hydrological importance of the area, showing the origins of the North Fork Powder River and North Fork Crazy Woman Creek, alongside smaller streams like Sourdough Creek and Baby Wagon Creek.
