Environment

The Ghost Theory blog had an interesting article recently about a phenomenon that I had not heard of before: strange sounds in the sky over Yellowstone Lake. Unlike the other recent "sky sounds" that have been fairly conclusively proven to be hoaxes, these sounds have been reported hundreds of times, over at least the last hundred years. The reports come from both inexperienced park visitors and well-established naturalists, guides, rangers, and other respected figures.

 

The sounds happen most often on a quiet morning, when the lake is still. An observer standing on the shores of the lake may hear a sound that seems to be approaching from a distance, like the whistling wings of a flock of ducks. The sound has a distinct element of horizontal motion, as if it is passing overhead or moving across the lake.
