Switzerland comprises three basic topographical areas: the Swiss Alps, the Swiss plateau or "middleland", and the Jura mountains along the northwestern border with France. 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 peaks of the Swiss Alps, the highest of which is the Dufourspitze at 4,634 metres (15,203 ft), countless valleys are found, many with waterfalls and glaciers. From these the headwaters of several major European rivers such as the Rhine, Rhône, Inn, Aare, and Ticino flow finally into the largest Swiss lakes such as Lake Geneva (Lac Léman), Lake Zürich, Lake Neuchâtel, and Lake Constance.
