Snow cover lingered in the Great Lakes region on February 16, 2008. Against the backdrop of snowy ground appear the deep blue waters of the Great Lakes and nearby water bodies. In this wintertime shot, the lakes are relatively ice-free, except for Lake Erie.
Huge sheets of ice carved out the U-shaped valleys that hold New York’s Finger Lakes. When they retreated north about 10,000 years ago, glaciers left deposits of gravel that dammed streams and caused the depressions to become lakes.
