During the Wisconsinan glaciation, the New York City region was situated at the edge of a large ice sheet over 1,000 feet in depth. The ice sheet scraped away large amounts of soil, leaving the bedrock that serves as the geologic foundation for much of New York City today. Later on, the ice sheet would help split apart what are now Long Island and Staten Island. COUNT 3
