Exactly 150 years later, a new 3D map of the USS Hatteras has been released that shows what the remains of the warship look like. The Hatteras rests on the ocean floor about 20 miles (32 kilometers) off Galveston, Texas, according to a release from the National
Oceanographic and Atmospheric Administration, which helped to sponsor the expedition to map the shipwreck.
The Hatteras was sunk in a battle with the Confederate raider CSS Alabama, and was the only Union warship sunk in combat in the Gulf of Mexico during the Civil War.
In the image above, the 3D sonar view of the USS Hatteras is from the vessel's port (left) side. More than half the hull lays buried in sediment. The curved tooth-like outline to the right is the remains of the stern and rudder.
