The Rhône
From the Rhône Glacier to the Mediterranean
▶ Play it onlineThe Rhône starts as meltwater from a glacier in the Valais, runs the length of that valley, fills Lake Geneva, and then crosses into France to meet the Saône at Lyon. From there it runs straight south to the sea. The plate shows how lopsided that is: the whole Alpine side, with the Isère, the Durance and the Arve, pours in from the east, while the Saône brings the long, flat country of Burgundy down from the north. The main stem is carved into the surface as a channel you can follow with a finger.
What a child works out
- A lake can be part of a river: the Rhône goes in one end of Lake Geneva and out the other.
- Mountains on one side and plains on the other make a very uneven basin.
- The Rhine and the Rhône start a few kilometres apart and reach different seas.
