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.

From 1860 to 1906, this area was the largest coal mining district in California. Five towns (Nortonville, Somersville, Stewartsville, Judsonville, and West Hartley) grew up around twelve major mines. Today the towns are gone, the buildings having been moved to nearby communities after the mines closed. Mine openings, tailings, railroad beds, and a pioneer cemetery are being preserved by the East Bay Regional Park District.
