This metal bondary disc between Alameda and Contra Costa Counties is located on the East Ridge Trail within a half mile of the Pinehurst Gate Staging Area of Redwood Regional Park (EBRPD). The trailhead is on Pinehurst Road roughly between Castro Valley and Moraga. The disc is set in concrete and elevated about one foot off the ground. Metal poles on each side protect the structure.
