Rhone River. The Rhône is one of the major rivers of Europe and has twice the average discharge of the Loire, rising in the Rhône Glacier in the Swiss Alps at the far eastern end of the Swiss canton of Valais, passing through Lake Geneva and running through southeastern France.
At Arles, near its mouth on the Mediterranean Sea, the river divides into two branches, known as the Great Rhône and the Little Rhône. The resulting delta constitutes the Camargue region.
The name Rhone continues the name Latin: Rhodanus in Greco-Roman geography. The Greco-Roman as well as the reconstructed Gaulish name is masculine, as is French le Rhône.
This form survives in the Spanish/Portuguese and Italian namesakes, el/o Ródano and il Rodano, respectively. German has adopted the French name but given it the feminine gender, die Rhone.
The original German adoption of the Latin name was also masculine, der Rotten; it survives only in the Upper Valais. In French, the adjective derived from the river is rhodanien, as in le sillon rhodanien, which is the name of the long, straight Saône and Rhône river valleys, a deep cleft running due south to the Mediterranean and separating the Alps from the Massif Central. Before railroads and highways were developed, the Rhône was an important inland trade and transportation route, connecting the cities of Arles, Avignon, Valence, Vienne and Lyon to the Mediterranean ports of
