USS San Diego Wreck
About USS San Diego Wreck
The armored cruiser USS San Diego sank off Long Island in July 1918 after an explosion that was later determined to be caused by a mine. The wreck lies upside down on a sandy seabed, and parts of the structure such as the keel are beginning to collapse after a century underwater. The maximum depth to the sand is 108 ft, making this a deep wreck dive.
