I enjoyed driving with one of my friends and visited a site of petroglyph last weekend. It was first time for me to visit the place. Though the friend have once experience to visit there, she was not sure to remember where it was. Eventually we have got there with a map and her memory.
The petroglyph is carved on single huge rock. It looks like scribble by children. What I was a bit shocked was that those petroglyph are not conserved by any special way. They are exposed by not only wind and rain but human who can touch and walk on them without prohibit prohibition. If those petroglyphes are valuable from point of historical view, it is sad to steadily and surly be ruined as one of human legacy.
