Lying within the Berchtesgaden Alps in the municipality of Sch�nau am K�nigsee, just south of Berchtesgaden and the Austrian city of Salzburg, the K�nigssee is Germany's third deepest lake. Located at a Jurassic rift it was formed by glaciers during the last ice age. It stretches about 7.7 km (4.8 mi) in the north-south direction and is about 1.7 km (1.1 mi) across at its widest point. Except at its outlet, the K�nigsseer Ache at the village of K�nigssee, the lake similar to a fjord is surrounded by steeply rising flanks of mountains up to 2700 m (8900 ft), including the Watzmann massif in the west
