Rancho Bernardo Style Rock Art.
Above is an example of Thee style known as Rancho Bernardo rock Art. The site we visited has several examples of beautiful Maze Rock Art. The site has been closed to the public, due to vandalism, and these photos had to be taken with a telephoto from a nearby trail. The amount of vandalism is heart breaking. The rock art is a bit worn and distant, though it is easily observed with a pair of binoculars. I almost missed them, except or the red color on the above rock. Once I had found the one a quick survey revealed others in the nearby rocks.
The above pictures show some Maze Type Rock art pictographs, both have been vandalized by white paint. The upper graffiti is actually over another panel. I have darken the picture a bit to bring out the rock art. The one on the elongated boulder actually wraps around the rock, look closely and you can see there is an extension at the bottom.
