A Mile Underground in the Mountain Con

Miners holding a sign reading "One Mile to Surface." This photo was probably taken when the one mile depth was first reached. The Mountain Con is the deepest mine on the Butte hill. Located at a surface elevation of about 6,000 feet, the mine today bears the words "Mile High, Mile Deep" on the side of a remaining structure. | Creator: C.
