Lake Superior is something else . . .
“Lake Superior is the largest, deepest, and coldest of the five Great Lakes. The other four emptied into its basin would leave room and then some for the ten thousand and more lakes Minnesota claims within its borders. Lake Superior’s water could cover North and South American with a wading pool nine inches deep. Agates of exceptional beauty are strewn along its beaches, with pebbles worn smooth by the action of its waves. Its rock is the oldest on the face of the earth. From most points on its shoreline of over two thousand miles, its opposite shore cannot be seen.” (opening paragraph of Everywhere in Chains by James Casper)
