Madeline Island is one of the Apostle Islands in Lake Superior. There's regular ferry service to it from Bayfield, Wisconsin. But when the lake freezes, residents use this type of vehicle to travel to and from the island. It's called an "ice angel" or "windsled."
It's an enclosed iceboat. Fans on the back push it over the surface. Although there's an ice road that Madeline Island's residents can drive cars over, many find the ice angel safer.
This is 1 of 10 unusual forms of public transportation rounded up by When on Earth. Others include amphibious vehicles in London and toboggans in Madeira.
