But look where the biggest pool of blue on Earth lies: smack dab over the eastern U.S. roughly between the Mississippi River and Appalachian Mountains.

In the global map, notice the particularly deep shade of blue over Lake Superior. That explains a lot – like the longest duration of lake ice on record – which took until the second week of June to finally melt away.
Residents of the eastern U.S. who are just starting to thaw out after the brutal polar vortex winter should appreciate what they experienced was an anomaly.
