Inside of a collapsed lava tube in northern Arizona is a set of Virgin Anasazi pictographs. They believed that caves were the entrance to the spirit world. This is a sacred place.
The pictographs are protected from the elements by the cave ceiling and as such, they are particularly vibrant. The reds, yellows, and whites are almost as pristine as the day they were painted, probably some 600 years ago.
