2024 Map of Ryan Peak

About this map

Ryan Peak and Glassford Peak dominate this high-altitude landscape in the Boulder Mountains, where the headwaters of several major Idaho river systems originate. The terrain serves as a significant hydrological divide, with the East Fork Salmon River flowing north while the North Fork Big Wood River and North Fork Big Lost River drain to the south and east. This 2024 survey documents the intersections of the Sawtooth National Forest and Challis National Forest, alongside the protected reaches of the Jim McClure-Jerry Peak Wilderness and Hemingway-Boulders Wilderness. The remote character of the area is underscored by primitive routes like Bowery Trl and Grand Prize Trl, which follow drainages such as Lost Mine Canyon and West Pass Creek into the high basins.
