The Finger Lakes are a group of eleven long, narrow, roughly north-south lakes in a section of Central New York in the United States. This region is defined as a bioregion. They are a popular tourist destination. The lakes' shapes reminded early map-makers of human fingers, and the name stuck. Cayuga (435 feet, 133 m) and Seneca (618 feet, 188 m) are among the deepest in the United States, with their bottoms well below sea level.
