1953 Map of Antioch South

About this map

Somersville and Nortonville represent the industrial heritage of the Mount Diablo coalfield on this map of the hills south of Antioch. The landscape is etched with the remnants of 19th-century mining, including coal mine tunnels near the West Hartley site and a Quarry near Stewartville. The area's transition from resource extraction to a managed watershed and residential buffer is visible through the Antioch Municipal Reservoir and the Mokelumne River Aqueduct cutting across the northern hills.
