Long Canyon and Marsh Creek


Long Canyon and Marsh Creek
36 bedrock mortars, 29 on one rock.

The location of this site near the mouth of Hog Canyon meant that this was a “gatehouse” settlement guarding one of the principal routes into the Volvon heartland. This was one of the bedrock mortar sites known to early 20th century Contra Costa County historians.

This site is just off Marsh Creek Road on private property. Be respectful.
