Does this Photo Show a Demon, an Angel or a Palm Tree?

This photo is going viral because people can't figure out if it's a demon, an angel or just a palm tree. It was taken by Richard Christianson in Laveen, Arizona on New Year's Day.

As you can see, it's a large, shadowy figure that appears to have wings. Many believe that it's an angel, but the most logical, and least fun, answer is that it's just a palm tree. Our guess is that it's the inside out lady with wings from the Heart Shaped Box video.
