Berkeley Pit Wikipedia

The underground Berkeley Mine was loed on a prominent vein extending to the southeast from the main Anaconda vein system. When open pit mining operations began in July 1955, near the Berkeley Mine shaft, the older mine gave its name to the pit. The openpit style of mining superseded underground operations because it was far more economical and much less dangerous than underground mining.
