Aar

Aar (Ger. Aare; Fr. Aroie), next to the Rhine and Rhone, the largest river in Switzerland, rises in the glaciers of the Bernese Oberland, forms the Falls of Handeck, 180 feet high, flows through the lakes Brienz and Thun, and passing the towns of Interlaken, Thun, Berne, Soleure, and Aarau, joins the Rhine above Waldshut after a course of 180 miles. Part of its waters are diverted by canal into the Lake of Bienne; its main tributaries are the Reuss and the Limmat. See GLACIERS.
