Police said Wednesday that they are 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 2 meters (6 ½ feet) under the surface on Friday and handed it in to police.

Divers on Tuesday carried out a thorough search of the area around where the bar was found, but didn’t find any more gold or other valuables.
