Ice Caves

Lake Superior, the biggest freshwater lake in the world, has something rare to offer this winter:  ice-filled caves which are accessible on foot.  The lake is nearly completely frozen over, so it's possible to walk out there a couple of miles (instead of boating) to the caves.

Pictures abound.  There's some excellent ones here at Minnesota Public Radio.  National Parks Traveler has a great video of the ice formations.
