Under normal circumstances, I can readily find the origins of weird things in Arizona, but there’s one north of Flagstaff that puzzles me. No one seems to know anything about what it is, why it’s there and who put it there. It is three weathered tree trunks (they look like junipers) standing next to each other, and someone painted strange faces on them. The images on the two smaller trunks are badly faded, but the face on the tallest one is still in relatively good shape. It resembles “The Scream,” the famous expressionist painting by Norwegian artist Edvard Munch in 1893.
