1951 Map of Snowdrift Mountain

About this map

Snowdrift Mountain and the Webster Range dominate this Idaho landscape, which sits atop the high-elevation continental divide between the Great Basin and Columbia River Basin. Surveyed in the late 1940s, the terrain is defined by its ridge-and-canyon structure, including the prominent Freeman Ridge and Dry Ridge. The map documents a sparsely populated region of the Caribou National Forest where human presence is marked primarily by isolated outposts such as Nate Ranch, Allemans Ranch, and the Trapper Cabin. Water sources like Greyhound Pass Spring and Goodhart Spring were critical for livestock and forest management. At the southern edge, the Clear Creek Guard Sta and Halfway House indicate the infrastructure supporting high-country travel and range administration during the mid-20th century.
