Fantastic "frozen wave" photos like this one have circulated on the internet to illustrate the 2008 Michigan cold snap. The accompanying text says they were taken in Macinaw City on Lake Huron. The photos are real, says Snopes, but the text is a hoax. The photos are from Antarctica, Dumont d'Urville Station, not Michigan, and the wavelike effect is caused when ice is lifted up and exposed by glaciation, then sculpted by extreme winds.
