When last week’s snowstorm and cold spell made its way through the Great Lakes, nearly 90 percent of Lake Erie froze over, according to the NASA Earth Observatory. The colorized picture above shows ice (pale blue) and snow (blue-green) formed on top of the lake.
A report by Jeff Masters, director of meteorology at Wunderground.com, showed that these high levels of ice coverage had not been seen on the Great Lakes since January 1994.
