The northern edge of the Antioch city limits meets the Southern Pacific railroad and industrial structures like the Filtration Plant and Oil Tanks. South of the urban center, the terrain rises into the Diablo Range, where industrial footprints and former coal mining operations are noted by Coal Mine Tunnels and a Quarry. Local history is visible through several former settlement locations, including Somersville (Site), Stewartville (Site), and West Hartley (Site), marking where early communities once thrived in the canyons.
