The Blue Ledge Mine is an inactive underground copper mine that has been classified as a Superfund Site by the Environmental Protection Agency (EPA) due to high concentrations of heavy metals. The mine is located approximately 3 miles south of the California–Oregon border in the Rogue River-Siskiyou
National Forest. It is within the Siskiyou Mountain range, and sits near a summit at about 4,800 feet above sea level. The underground mining excavations span over 2 miles, and it is one of the largest mining operations to have existed in the region.
