Swirl of Mist Ghost Picture

Judy from Gladewater Texas sent us this cool pic. It sort of looks like ectoplasm, yet has a distinct, swirling pattern to it on the left of the photo:

"This picture was taken on a weekend trip to Oklahoma. We were on a mountain overlook in the Quachita Mountain range. We had stopped a few miles back and visited an old cemetery. We were amazed when we saw this photo. It was a warm, clear day."
