ORION CONSTELLATION OVER LAKE LUCERNE, SWITZERLAND (IMAGE)

The lake has a complicated shape, with bends and arms reaching from the city of Lucerne into the mountains. It has a total area of 114 km² (44 sq mi), an elevation of 434 m (1,424 ft), and a maximum depth of 214 m (702 ft). Its volume is 11.8 km³. Much of the shoreline rises steeply into mountains up to 1,500 m above the lake, resulting in many picturesque views including those of Mount Rigi and Mount Pilatus.
