1978 Map of Fourth of July Peak

About this map

Targhee National Forest and the Snake River Range dominate this 1970s landscape, where the rugged topography of the Mountains gives way to the agricultural irrigation of the Teton Basin. The map captures a transition from resource extraction at the Walton Mine to the developed water systems of the Spencer Canal and various other irrigation channels. High-altitude landmarks like Fourth of July Peak, Squirrel Mtn, and Rocky Peak overlook a network of backcountry travel routes, including the Pine Creek Pass and numerous Pack Trails. The drainage patterns are clearly defined by the Teton River and its tributaries such as Rainey Creek and Humble Creek, illustrating the vital water resources that supported the regional economy between the mountains and the basin floor.
