On a foggy night in 1888, the passenger steamer City of Chester
was headed out of San Francisco Bay when disaster struck. The 202-foot boat was rammed by a much larger steamer, the Oceanic
, coming into the bay from Asia. Sixteen people died in the accident, and the City of Chester
quickly sank to the bottom. This multibeam sonar image from NOAA is the first look at the steamer in well over a century.
