Crockett Hills Regional Park – June 17 Gallery | Posted on June 17, 2013 by Sean M. Brown After 15 minutes or so of climbing from the staging area trailhead, turned around to this view. Beautiful clear morning. There’s a Killdeer flying through this shot Looking towards Oakland you don’t notice the refineries, bridges and 101 A fenced off tunnel under Crockett Blvd. On the way through the parking lot I spotted this tunnel. The Deer was relaxing in the shade.
