In 1664, the city was named in honor of the Duke of York, who would become King James II of England. James's older brother, King Charles II, had appointed the Duke proprietor of the former territory of New Netherland, including the city of New Amsterdam, which England had recently seized from the Dutch. During the Wisconsin glaciation, 75,000 to 11,000 years ago, the New York City region was situated at the edge of a large ice sheet over 2,000 feet (610 m) in depth. The erosive forward movement of the ice (and its subsequent retreat) contributed to the separation of what is now Long Island and Staten Island. That action also left bedrock at a relatively shallow depth, providing a solid foundation for most of Manhattan's skyscrapers.
