Lake Superior Could Completely Freeze Over This Winter

Lake Superior hasn't completely frozen over in two decades.

But an expert on Great Lakes ice says there's a "very high likelihood" that the three-quadrillion-gallon lake will soon be totally covered with ice thanks to this winter's record-breaking cold.

The ice cover on the largest freshwater lake in the world hit a 20-year record of 91 percent on Feb. 5, 1994.
