Greenpoint Brooklyn Public Library Glacial outcroppings

Glacial outcroppings

These rocks have a story to tell you. During the last ice age, the Laurentide Ice Sheet began expanding above the area where you're now standing to heights that exceed Manhattan's current skyline. This granite outcropping is inspired by the sculpting force and direction of the ice sheet during the glacial formation and melting retreat that occurred approximately 18,000 years ago.
