Travel back in time at East Bay Parks this month
CONTRA COSTA COUNTY, CA (May 13, 2022) — Black Diamond Mines Regional Preserve will help to celebrate the city of Antioch’s 150th anniversary with a day of special activities from 10 a.m. to 4 p.m. on Saturday, May 21.
Park naturalists wearing 19th century attire will greet visitors, and park staff will conduct free first-come, first-served tours of the park’s underground mining museum.
A free shuttle to the event will run every 20 minutes from Somersville Towne Center Mall.
From the mid-19th Century through the early 20th, the area now including the preserve was California’s largest coal mining region. The mining towns of Somersville and Nortonville were Contra Costa County’s most populous.
The coal-mining era was followed by a silica-mining period from about 1920 through the mid-l940s. Economic factors put an end to the mining, and ranching resumed. East Bay Regional Park District acquired the core of the present parklands in the early 1970s.
Tours of the former mining tunnels are restricted to ages seven and older for safety reasons. However, the park’s underground Greathouse Visitor Center is open to all ages, and contains photos and artifacts from the mining days.
Black Diamond Mines is located at the end of Somersville Road, 3½ miles south of Highway 4 in Antioch. There’s a parking fee of $5 per vehicle when the kiosk is attended. For information, call 510-544-2750.
