McGinty Mountain gold prospect tunnels

Today my friend Jimmy and I went hiking near his house in Jamul, CA up nearby McGinty Mountain.  Long ago it was thought that here was gold the region around McGinty Mountian.  There are a number of horizontal prospect shafts that can be seen today.  The picture at the right is one of the three that we visited on today's hike.

I usually won't go in these abandoned shafts but this one looked pretty safe so I went about 50 ft into the 100 ft long tunnel.
