19000 BC: Peak of the Ice Age in New York City

At the apex of the Ice Age, the Laurentide Ice Sheet would reach a maximum thickness of 2,000 feet – blanketing even our tallest buildings. The weight of this mass would compress the land below for millennia, forming a dense bedrock (the famous Manhattan schist) which makes the ideal foundation for the weight and height of today’s modern skyscrapers.
