lake lucerne ,switzerland

Lake Lucerne is a lake in central Switzerland and the fourth largest in the country.

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.

The Reuss River enters the lake at Flüelen and exits at Lucerne. The lake also receives the Muota (at Brunnen) Engelberger Aa (at Buochs), the Sarner Aa .

It is possible to circumnavigate the lake by road, though the route is slow, twisted, and goes through tunnels part of the way. Steamers and other passenger boats ply between the different towns on the lake. It is a popular tourist destination, both for native Swiss and foreigners, and there are many hotels and resorts along the shores. In addition, the meadow of the Rütli, traditional site of the founding of the Swiss Confederation, is on the southeast shore of the lake. A 35 km commemorative walkway, the Swiss Path, was built around the lake to celebrate the country's 700th anniversary.

Geography

Lake Lucerne borders on the three original Swiss cantons of Uri, Schwyz, and Unterwalden (which today is divided into the Cantons of Obwalden and Nidwalden), as well as the canton of Lucerne, thus the name Vierwaldstättersee (Lake of the Four Forested Cantons). Many of the oldest communities of Switzerland are along the shore, including Küssnacht, Weggis, Vitznau, Gersau, Brunnen, Altdorf, Buochs, and Treib

Lake Lucerne is singularly irregular and appears to lie in four different valleys, all related to the conformation of the adjoining mountains. The central portion of the lake lies in two parallel valleys whose direction is from west to east, the one lying north, the other south of the ridge of the Bürgenstock. These are connected through a narrow strait, scarcely one kilometre wide, between the two rocky promontories called respectively Untere and Obere Nase. It is not unlikely that the southern of these two divisions of the lake—called Buochser See—formerly extended to the west over the isthmus whereon stands the town of Stans, thus forming an island of the Bürgenstock. The west end of the main branch of the lake, whence a comparatively shallow bay extends to the town of Lucerne, is intersected obliquely by a deep trench whose south-west end is occupied by the branch called Alpnacher See, while the north-east branch forms the long Bay of Küssnacht, Küssnachter See. These both lie in the direct line of a valley that stretches with scarcely a break parallel to the chain of the Bernese Alps from Interlaken to Lake Zug. At the eastern end of the Buochser See, where the containing walls of the lake-valley are directed from east to west, it is joined at an acute angle by the Bay of Uri, or Urner See, lying in the northern prolongation of the deep cleft that gives a passage to the Reuss, between the Bernese chain and the Alps of N. Switzerland.
