1. Seven Devils Mines Marker
More than a century ago, miners faced a hopeless problem of hauling copper ore to this canyon for shipment to smelters.
They started with Albert Kleinschmidt's road grade down from their mine, more than a vertical mile above Snake River, and more than 30 miles downstream from here. After a steamboat failed in 1891, a railroad (now under water) was built past here to their river landing. That did not work either. Large ore trucks finally solved their problem in 1968.
Erected by Idaho Historical Society. (Marker Number 378.)
