The Clamshell Petroglyphs are an easy to reach Anasazi site just outside of Fredonia, Arizona. These petroglyphs and pictographs are so old they are hard to see at all. There are some interesting designs though; including some anthropomorphic figures, a water glyph, a six-toed footprint, and spirals. Lots of spirals. Obviously, an important symbol here.
The site must have once been a roadside picnic area because there are a few picnic tables scattered amongst the juniper trees. The place has the feel of abandonment now. But if you are in the area, it is a fine place to have lunch and relax with the spirits of the Ancients.
