2011 Map of Harry Canyon

About this map

The White Knob Mountains dominate the eastern landscape of this Custer County region, where the high-altitude drainage systems of central Idaho converge. The hydrology of the area is defined by the Big Lost River in the north and the East Fork Big Lost River in the south, both of which are fed by numerous seasonal and perennial streams such as Willow Creek and Bady Creek. Evidence of aviation infrastructure is visible with the Star 'S' Ranch Airport situated along the river valley and the Twin Bridges Airport further west, supporting access to these remote ranching and mountain reaches. Deep geological incisions like Harry Canyon, Wildcat Canyon, and the appropriately named Dry Canyon illustrate the erosive power of the watershed. Practical transit is limited to corridors like Trail Creek Rd, which follows the natural contours of the river valley through the foothills.
