2023 Map of Antioch South

USGS Topo · Published 2023

About this map

The Black Hills and the northern slopes of the Diablo Range define the rugged southern landscape of this 2023 survey. Critical water infrastructure serves the modern Contra Costa region, including the Mokelumne Aqueduct, the Contra Costa Canal, and the Contra Loma Reservoir. Historical traces of the area's mining and ranching heritage remain visible in the placement of Rose Hill Cem and the naming of Empire Mine Rd, alongside former settlement sites like Somersville, Stewartville, and West Hartley. The map captures the meeting point of the San Joaquin Valley and Sacramento Valley in the north, where residential growth from Antioch, Pittsburg, and Brentwood pushes toward the dramatic elevation changes of the Deer Valley and Lone Tree Valley. Local landmarks such as Marsh Creek Springs and several canyons, including Oil Canyon and Irish Canyon, illustrate the complex drainage patterns feeding into Marsh Creek.
