Alpine Rhine
The Alpine Rhine (German: Alpenrhein, pronounced [ˈalpn̩ˌʁaɪn] ) is the section of the river Rhine from its source in the Swiss Alps to Lake Constance. It begins in the centre of the Swiss canton of Grisons (Kanton Graubünden), and later forms the border between Switzerland to the west and Liechtenstein to the east, and later between Switzerland and Austria.
