Texas -- The remains of the only U.S. Navy ship sunk in the Gulf
of Mexico during Civil War combat now can be seen in 3-D sonar
images from the Gulf's murky depths, revealing details such as a
shell hole that may have been among the ship's fatal wounds. The
high-resolution images of the 210-foot, iron-hulled USS Hatteras
are being released this month to coincide with the 150th
anniversary of the battle where the ship was lost. Besides the
shell hole, they also show previously unknown details like a
paddle wheel and the ship's stern and rudder emerging from the
shifting undersea sands about 20 miles
