2024 Map of Rock Roll Canyon

About this map

The high alpine intersection of the Boulder Mountains and Pioneer Mountains dominates this recent survey of the Idaho interior. This area serves as a significant hydrological divide, where the East Fork North Fork Big Wood River begins its descent through the Hemingway-Boulders Wilderness. The map traces several vital high-altitude transit points, most notably Trail Creek Summit, where Trail Creek Rd provides a primary route across the rugged divide separating the Sawtooth National Forest from the Challis National Forest. A network of drainage systems, including Rock Roll Canyon and Neal Canyon, underscores the complex vertical relief of the territory. The presence of Lake Or Lakes and various gulches like Steep Gulch and Basin Gulch highlights the glacial and erosional forces that have shaped this high-country landscape, which remains largely defined by federal wilderness and forest management boundaries.
