New York Aquarium

In the natural wonders department, the East Coast has its very own version of the Grand Canyon. Sitting under about 60 feet of water at the mouth of the Hudson River, the Hudson Canyon was created during the last ice age 10,000 years ago. Located on the continental margin (the zone of the ocean floor that separates the thin oceanic crust from thick continental crust) off New York and New Jersey at the outlet of the Hudson River, it's so deep (estimated to be at least a mile) that we don't know much about what lies at the bottom, but we do know that it's a biodiversity hotspot. Jon Forrest Dohlin, vice president of the Wildlife Conservation Society and director of the New York Aquarium tells NYMetro that due to the unique phenomenon of an upwelling of cold water mixing with warmer surface currents, the submarine canyon is able to provide a home for hundreds of species from plankton to turtles, sharks, whales and birds.
