Photographer spooked off Big Spirit Lake before he gets his photo

4 February 2013 about 5am Spirit Lake, Dickinson County, Iowa 1 witness

Account

Before dawn the witness walked from a parking lot toward the frozen lake to photograph the sunrise. He heard three deliberate wood-on-wood knocks to the north, followed immediately by a bottle-on-metal clattering sound from a closer area to the south. He saw no people or animals, took no photograph, and left the area quickly feeling compelled to leave.
