Empire Mine Road – Antioch

Empire Mine Road  –  Antioch


That’s the east side of Mt Diablo in the near distance.

There’s parking by the side of the road.


Maybe a mile out you’ll want to go up behind the old haunted slaughterhouse.


26 bedrock mortars on this rock and several more nearby.

A grassland environment today, and probably always.




The numbers indicate how many bedrock mortars we have counted at each site.
