Photo taken from Inwood Hill Park. The bridge connects the northern tip of Manhattan with the Bronx Borough. The body of water is the northern end of the East River that connects with the Hudson River. The Hudson River Palisades can be seen on the far horizon. This area is also known as Spuyten Duyvil.
