MOUNT DIABLO COAL FIELD
Historical Landmark |
| Description: This was the largest coal-mining district in California from 1860 to 1914, with five towns-Nortonville, Somersville, Stewartsville, Judsonville, and West Hartley-near twelve major mines. Today the towns are gone, their buildings moved to other communities after the mines closed - the East Bay Regional Park District is preserving mine openings, tailings, railroad beds, and a pioneer cemetery. |
