About this map

Sawtooth National Forest dominates this high-elevation landscape, where a sophisticated network of trails and forestry roads provides access to the central Idaho backcountry. The map captures the significant verticality of the region, anchored by prominent summits such as Boyle Mtn, Fox Peak, and Bear Peak. The drainage patterns are clearly defined, with Baker Creek and its various forks flowing through deep cuts like Boyle Canyon and Narrow Gorge.

Modern recreational use is evidenced by the named trail systems, including the Osberg Ridgeline Trail and the Adams Gulch Trail, which navigate the ridgelines between drainages. The naming conventions throughout the quadrangle, from Badger Gulch to Blue Clay Gulch, reflect the historical identification of specific drainages used by early surveyors and foresters. Significant geological markers like Castle Rock and the Red Rocks further define the varied terrain of the Boulder Mountains.
