Custer County, Administrative division in Central Idaho, US
Custer County extends across 4,938 square miles of diverse terrain, including mountain ranges, river valleys, and desert regions in the heart of Idaho.
The county, established in 1881, received its name from the General Custer Mine where gold deposits were discovered in 1876, sparking regional development.
The county preserves multiple ghost towns from mining periods, including Bayhorse, Bonanza, and Custer, which demonstrate the regional industrial heritage.
The county seat of Challis, located at 801 E. Main Avenue, functions as the primary center for government services and administrative operations.
Mount Borah, rising 12,662 feet within the Lost River Range, stands as the highest peak in Idaho and defines the eastern section of Custer County.
