A teenager has made an unexpected find while swimming in a lake in the German Alps: a 17.6-ounce bar of gold. Police say they're still trying to figure out where the bar comes from and how it got into the Koenigssee lake, a popular tourist destination near Berchtesgaden on the border with Austria. The 16-year-old girl, who was on vacation, found it around six feet under the surface on Friday and handed it in to police. Divers yesterday carried out a thorough search of the area around where the bar was found, but didn't find any more gold or other valuables. (A gold bar found in Florida is worth up to $500,000.)
