We were trying to get to Mom's Wild Ride and ended up here, but it would have been a loooong walk. It was a neat spot though, so we thought we'd share it.
The cache is what appeared to be very old black prescription bottle that I thought was Pure Corn cache. You can see it from the right, though very awkward, angle.
The trailhead provides access to the Bay Trail and other nearby caches (though driving would be faster).
