Near the entrance to
Petroglyph Canyon is a Picnic area and there are some images by there. Some of
these images are very well preserved by the effects of erosion seem to be
minimized and the 'varnish accumulation processes seem to be working well or
were working well as they do not seem to have been eroded yet. Note the
reflection of the light from the sky on the shiny surface of the patina.
