This amazing video shows Lake Superior frozen solid.

For the first time since 2009, the coastline of Lake Superior, the largest of the Great Lakes of North America, has frozen solid. Solid enough so that people are actually able to go out onto the ice and into the sea caves that line the shore near Wisconsin's Apostle Islands.

The sight is beautiful and majestic but the massive ice stalagmites do look very scary and dangerous.

“For most people, walking on a frozen Great Lake is just a remarkable experience psychologically, let alone physically,” said National Lakeshore superintendent Bob Krumanaker. “It’s pretty solid generally and depending on the visibility it could be white as far as you can see. But you know the lake is under it and sometimes you can even feel the ice move a little bit.”

 “You’re looking at these beautiful rock formations, but they’re covered by stalactites and stalagmites made of ice,” he said.

“And then if you carefully crawl under some of that ... the ice is completely smooth and generally completely clear underneath it. So it’s like there’s a glass floor that you can see the bottom of the lake," he added.

Lake Superior is the largest freshwater lake in the world. It is also the coldest, deepest and highest in elevation of any of the Great Lakes.
