The remarkably well-preserved body of a scuba diver who vanished in Lake Tahoe 17 years ago has been found on a ledge deep in the mountain lake on California’s border with Nevada, authorities said on Tuesday. The body of Donald Christopher Widecker, 44, was pulled from the lake on July 27, four days after divers stumbled across it while exploring a granite cliff 270 feet (82 metres) below the surface. Widecker disappeared in the frigid waters on July 10,1994, after apparently suffering a medical or equipment problem. Tahoe is the second-deepest lake in the United States, reaching depths of 1,645 feet (501 metres). “This group was doing just a routine planned dive and it was literally a needle in a haystack,” El Dorado County Sheriff’s spokesman Sgt. Jim Byers told Reuters.
