The ice caves of Lake Superior

Over the past few months more than a hundred thousand people have journeyed to the Northern tip of Wisconsin for a chance to see the dozens of ice caves stretching for over a mile along the coast. What makes the caves truly unique is that this is the first winter in five years they have been accessible. Visitors can only get to the caves by marching over ice-covered Lake Superior. Inside each cave visitors find a unique icy masterpiece, all courtesy of Mother Nature.

Diver comes face-to-face with shark

Jason Dimitri was spearing lionfish in the western Caribbean Sea when a reef shark came out of no where and attacked him. He was seventy feet below the surface. The diver filmed the action on his GoPro 3 camera and managed to capture the moment the Caribbean reef shark swam towards him with its jaws open. Dimitri says he was able to fend the shark off with his spear. Despite this close call, Dimitri wrote on his YouTube page that he will definitely be going back in the water.
