The Bonanza King Mine was a silver producer discovered in 1880. By 1883, the town of Providence had sprung up to support the miners and their habits. A post office, a saloon, two general stores, and two hotels were reportedly the town’s standouts. The first boom ceased in 1885 because of plummeting silver prices. According to Philip Varney’s “Southern California’s Best Ghost Towns,” the Bonanza King experienced two revivals from 1906 to 1907 and from 1915 to 1920. We saw one portal and tunnel that looked to be newer, but no mining was actively underway.
