I call this the "Moonstone orb" because of the different blend of colors. It looks like moonstone.

This photo was taken out near Caledon, ON in a man made Cave next to a river.

In this particular area, there is a river right down the bank here. An unknown "force" touched Loretta B.'s hair in this spot.
It wasn't her sudden shriek that made us jump .. it was the fact when we turned and looked, a patch of hair was standing straight up by itself for a quick moment then quicky fell limp.
