Deep Freeze, also known as Marie Horn, is a 231’x33′ vessel built in 1958 and sunk on October 1, 1976. Resting at 135 feet depth with a 30-foot relief in Miami-Dade County, this site is famous for being covered in monofilament lines and attracting big fish. It’s a prime deep-water destination for advanced divers seeking dramatic structure and marine biodiversity.
