1967 Map of Ryan Peak

About this map

Ryan Peak and Glassford Peak dominate the high-altitude divide between the Sawtooth National Forest and Challis National Forest in this late-1960s survey. The landscape is defined by the headwaters of major Idaho drainage systems, including the East Fork Salmon River and the North Fork Big Lost River. High-elevation landmarks like the Bowery Guard Sta and a thermal Spring (Hot) near the confluence of West Pass Creek indicate the remote administrative and natural features of the era.
