About this map

Mt Bonneville and the surrounding peaks of the Washakie National Forest dominate this 1930s-era survey of the high Wyoming wilderness. The landscape is defined by the Continental Divide, which separates the drainage basins and provides the backbone for the Continental Divide Trail. This map captures a moment before modern recreation infrastructure, when access was limited to backcountry routes like the Scab Creek Trail and the Washakie Trail.

Remote outposts such as the South Fork Guard Sta, John Day Cabin, and a Cow Camp provide evidence of early administrative and agricultural activity in these high elevations. Genealogists and historians can trace the specific passes used by early travelers, including Hailey Pass and Washakie Pass, while identifying dozens of named alpine lakes like Middle Fork Lake and Raid Lake that have long served as landmarks for mountain expeditions.
