In the state of New York, there are a series of 11 almost parallel and closely spaced lakes which are incredibly oblong. The reason for this is that each of these lakes completely formed during the last 2 million years, being owed to the action of ancient glaciers which once buried the landscape. This video will discuss how each of these lakes formed, such as Seneca Lake, and describe the difference between "U" and "V" shaped valleys.
