article: Switzerland
candidates: Extending across the north and south side of the Alps in west-central Europe, Switzerland encompasses a great diversity of landscapes and climates on a limited area of . The population is about 7.9 million, resulting in an average population density of around 190 people per square kilometre (485/sq mi). The more mountainous southern half of the country is far more sparsely populated than the northern half. In the largest Canton of Graubünden, lying entirely in the Alps, population density falls to 27 /km² (70 /sq mi). Switzerland lies between latitudes 45° and 48° N, and longitudes 5° and 11° E. It contains three basic topographical areas: the Swiss Alps to the south, the Swiss plateau or middleland, and the Jura mountains on the north. The Alps are a high mountain range running across the central-south of the country, comprising about 60% of the country's total area. Among the high valleys of the Swiss Alps many glaciers are found, totalling an area of 1,063 square kilometres. From these originate the headwaters of several major rivers, such as the Rhine, Inn, Ticino and Rhône, which flow in the four cardinal directions into the whole of Europe. The hydrographic network includes several of the largest bodies of freshwater in Central and Western Europe, among which are included Lake Geneva, Lake Constance and Lake Maggiore. Switzerland has more than 1500 lakes, and contains 6% of Europe's stock of fresh water. Lakes and glaciers cover about 6% of the national territory. About a hundred of Switzerland's mountain peaks are close to or higher than . At , Monte Rosa is the highest, although the Matterhorn () is probably the most famous. Both are located within the Pennine Alps in the canton of Valais. The section of the Bernese Alps above the deep glacial Lauterbrunnen valley, containing 72 waterfalls, is well known for the Jungfrau () and Eiger, and the many picturesque valleys in the region. In the southeast the long Engadin Valley, encompassing the St. Moritz area in canton Graubünden, is also well known; the highest peak in the neighbouring Bernina Alps is Piz Bernina (). The more populous northern part of the country, comprising about 30% of the country's total area, is called the Middle Land. It has greater open and hilly landscapes, partly forested, partly open pastures, usually with grazing herds, or vegetables and fruit fields, but it is still hilly. There are large lakes found here and the biggest Swiss cities are in this area of the country. The largest lake is Lake Geneva (also called Lac Léman in French), in western Switzerland. The Rhône River is both the main input and output of Lake Geneva.
