Lake Superior’s ice caves

Ice Caves, Apostle Islands National Lakeshore

The extreme cold this winter in Wisconsin has created spectacular ice formations at Apostle Islands National Lakeshore. The destination usually requires a boatride to reach, but Lake Superior’s frozen state has made it accessible by foot for visitors. The last time weather conditions permitted such access was in 2009.

See, and share, more photos in the Ice Caves of Apostle Islands gallery and Lake Superior group.
