1964 Map of Snowyside Peak

About this map

Sawtooth National Forest dominates this mid-1960s landscape, where five central Idaho counties—Blaine, Boise, Custer, Elmore, and Alturas—converge at high-altitude divides. The area is defined by a dense concentration of glacial basins, including Toxaway Lake, Alice Lake, and Pettit Lake, which feed the drainages of the South Fork Payette River and Alturas Lake Creek. While primarily a wilderness of granite summits like Snowyside Peak and Payette Peak, human activity is centered on the Alturas Inlet Campground and a scattered network of trails. A solitary prospect near Eureka Gulch and a mapped jeep trail reflect the region's history of small-scale mineral exploration and early recreational access. The map captures a moment before modern wilderness designations further restricted mechanized travel through these headwaters.
