Petroglyphs

I'm ashamed to admit, that I have lived in, or close to, Tiburon, for some 45 years, yet today was the first time I visited the nearby petroglyphs in the Ring Mountain Open Space Preserve! These circles were carved centuries ago by pre-Columbian Coast Miwok Indians on hard bluechist rock, and were probably spiritual in nature. The word "petroglyph" comes from the Greek "petros" (stone), and "glyphein" (to carve).
