Near Antioch in Contra Costa County, California — The American West (Pacific Coastal)
Coal was carried by rail from the mines to Pittsburg Landing on the San Joaquin River, and from there by riverboat to markets in San Francisco, Stockton, and Sacramento.
By the late 1800s, mines began to close due to increased production costs and competition from higher quality Washington Territory coal. The town of Somersville slowly died.
Mine waste rock piles, exotic trees planted by residents, and Rose Hill Cemetery are all that remain.
Erected by East Bay Regional Park District.
