San Bernardino County:
Like the New York Mountains to the north, the first discoveries made in the Providence Mountains were for silver. These discoveries, made in 1863, transformed the Macedonia Canyon area into the mining camp of Providence City. In 1880 another significant silver discovery was made at the Bonanza King. With the decline in silver prices, however, attention was turned toward gold, and the Hidden Hill, Gold Valley and Out West mining camps sprang up. During World War II, the immense iron deposits in Foshay Pass were mined, and silver, gold and copper mining has occurred at various places in the range during this century.
