Staten Island Boat Graveyard
This marine scrapyard has been an official dumping ground for water vessels since the 1930s. Formally known as the Donjon Iron and Metal Scrap Processing Facility the mud and shallow water mostly hold tugboats and cargo ships. There are "no trespassing" signs although marine historians love to row through the area in boats or kayaks. It's apparently not easy to get to so you might want to take a ride with one of those marine historians!
