1953 Map of Antioch South

USGS Topo · Published 1984

About this map

Somersville and Nortonville sit at the northern edge of the hills, marking the historical industrial activity of the Mount Diablo coalfields. This 1953 survey, updated in 1980, shows a landscape transitioning from resource extraction to managed regional spaces like Contra Loma Regional Park. Evidence of the area's subterranean history is visible through Coal Mine Tunnels near West Hartley, while the valley floors are defined by significant water infrastructure including the Contra Costa Canal and the Mokelumne Aqueduct. Further south, the rural character of Morgan Territory is preserved, anchored by the Morgan Territory Sch. The northern edge displays the urban expansion of Antioch, including the Antioch HS and the Antioch Municipal Reservoir, contrasting with the rugged canyons and valleys like Horse Valley and Briones Valley that dominate the central terrain.
