The lakes they call Great

NYTimes: From Montreal to Minnesota, by Inland Sea

I was so used to driving and flying, my understanding of North America had become distorted. Then I took a slow boat through four Great Lakes. I saw every mile.

The Great Lakes basin spans 10 degrees of latitude and 18 degrees of longitude — set almost exactly between the Equator and the North Pole. The circumference of all five lakes combined is 10,500 miles, nearly half the distance around the world. An average of 200,000 cubic feet of precipitation falls somewhere on the lakes every second.
