The seven large Finger Lakes in central New York state were formed when the last Pleistocene ice cap melted back and flooded valleys previously overdeepened by scouring of the advancing glacial ice. A thick veneer of glacial debris, not shown here, overlies the lower Paleozoic bedrock indicated on the map. The native American Iroquois believed that the fan-shaped array of lakes are marks from the hand of the Great Spirit.
