About this map

White Mountains topography dominates this high-altitude survey of the Challis National Forest and Sawtooth National Forest. The landscape is defined by massive peaks like Big Black Dome and Pyramid Peak, separated by deep drainage systems such as Howell Canyon and Bellas Canyon. This area represents a critical watershed for the East Fork Big Lost River, where high alpine water bodies like Bellas Lakes, Round Lake, and Clear Lake feed into a network of mountain streams.

Evidence of traditional land use and backcountry access is visible through the Copper Basin Cow Camp and several established recreation areas, including the Lake Creek Recreation Site and Broad Canyon Recreation Site. The eastern portion of the sheet opens into the Copper Basin, featuring the distinctive The Potholes and Copper Basin Flat. These features, connected by primitive Pack Trails, illustrate the transition from jagged peaks to the broad, high-valley floors used for seasonal grazing and remote mountain travel.
