Ghost Pictures: Alcove Springs

We were sent this e-mail and ghost picture from Loretta Klose of Lehigh, Kansas. Several things can cause a mist, such as insects, moisture and of course ghostly ectoplasm energy:

"This was taken at Alcove Springs in Marshall County, KS and stop that the Donner party made before their tragic end. The first one of their group died while they were camped here and she is buried on site. What is the mist - it wasn't visible to the naked eye when I took the picture."
