a little geography lesson for today

At the end of the last ice age, over one hundred-thousand years ago, massive sheets of ice, called glaciers, advanced southward from Canada carving deep trenches in the earth like a trowel. As the earth warmed and the glaciers receded, the trenches filled with water and formed what we now know as the Finger Lakes. 
One way that I love looking at the Finger Lakes is from the sky on a clear day when you can understand the formation of each lake.
