Inwood Hill Park

There's old New York, and then there's old New York. Inwood Hill Park is a living piece of old New York. Evidence of its prehistoric roots exists as dramatic caves, valleys, and ridges left as the result of shifting glaciers. Evidence of its uninhabited state afterward remains as its forest and salt marsh (the last natural one in Manhattan), and evidence of its use by Native Americans in the 17th century continues to be discovered.
