From there it continues into Puerto Rico, and the Virgin Islands. Part of the Puerto Rico Trench, the deepest part of the Atlantic Ocean (roughly 8,400 metres or 27,600 feet), lies along this border. The Puerto Rico Trench is at a complex transition from the subduction boundary to the south and the transform boundary to the west.
Desecheo Island sits on the Desecheo ridge, a narrow east–west ridge that extends west from the northwest corner of Puerto Rico. The ridge forms the southern boundary of the 13,123 ft (4,000 m) deep Mona Canyon which extends toward the north into the Puerto Rico Trench.
