2015 Map of Antioch South

About this map

Rose Hill Cemetery and the nearby Nortonville Pass serve as landmarks for the industrial history of this part of Contra Costa County. The landscape is defined by the transition from the dense residential developments of Antioch and Pittsburg in the north to the canyon-riven foothills of the south. Evidence of the region's mining past is visible through the Coal Mine Tunnels near West Hartley, along with former settlement sites like Somersville and Stewartville. Critical water infrastructure supports this growing suburban corridor, including the Mokelumne Aqueduct, the Contra Costa Canal, and the Antioch Municipal Reservoir. Toward the south, the terrain opens into broader valleys such as Lone Tree Valley and Briones Valley, where Marsh Creek Road winds toward Marsh Creek Springs.
