Via the Detroit News, video of a giant fog bank rolling ominously over Lake Michigan like something out of Lord of the Rings:
The footage was taken by a father and son duo fishing in northern Michigan.
According to the National Weather Service, what the Ballards experienced is known as advection fog.
“The fog develops when warm moist air moves over really cold lake water,” meteorologist Deb Elliott said. “Fog develops as the air is cooled and is then moved along by wind. It can very thick and extensive; if they were swallowed up in it, their visibility could drop to almost zero.”
The pair found their way to shore safely with a GPS device.
