World War II "ghost boat" emerges in drought-stricken California lake: "Its sinking remains a mystery"

Low water levels in California's drought-stricken Shasta Lake have revealed the long-lost wreckage of a ship that served in World War II.  The U.S. Forest Service says the amphibious Higgins landing craft — referred to as the "ghost boat" — appeared last fall in the drought-stricken reservoir.

Markings on the boat's side confirmed it was used on the USS Monrovia, the battleship that served as Gen. George Patton's headquarters during the invasion of Sicily. Dwight D, Eisenhower, who planned and oversaw the invasion of Normandy on June 6, 1944, was also on board the ship at one point.

The ship went on to serve in several missions, which reportedly included the invasion of Tarawa, where more than 1,200 Marines died in just 76 hours.
