About this map

Boise National Forest dominates this high-altitude landscape in Boise County, defined by a series of steep drainage basins and prominent ridges. The northern edge follows the course of the South Fork Payette River, where the Idaho City-Stanley-SH 21 provides the primary corridor for movement through these mountains. Elevations climb rapidly south of the river toward the crest of Ten Mile Ridge, which serves as a major topographical spine for the quadrangle.

Water distribution is characterized by numerous seasonal and perennial flows, including Tenmile Cr and the Crooked River, which carve deep V-shaped valleys into the granite. To the south, the terrain descends toward the Bear River and Little Silver Cr. The map preserves local nomenclature through names like Frank Creek Spur and Mac Donald Creek, reflecting a history of land use and exploration within this protected forest domain.
