Bellegarde station

The canton of Valserhône (before March 2020: canton of Bellegarde-sur-Valserine) is an administrative division in eastern France. At the French canton reorganisation which came into effect in March 2015, the canton was expanded from 12 to 15 communes (2 of which were merged into the new communes Surjoux-Lhopital and Valserhône):

Valserhône (French pronunciation: [valsəʁon] ; Arpitan: Vâlcerôno) is a commune in the Ain department in the Auvergne-Rhône-Alpes region in Eastern France. It is the result of the merger, on 1 January 2019, of the communes of Bellegarde-sur-Valserine, Châtillon-en-Michaille and Lancrans. In 2018, the three communes had a combined population of 16,431, with Bellegarde-sur-Valserine as the major population centre. This makes Valserhône the third-most populated commune of Ain, after Bourg-en-Bresse and Oyonnax.

Bellegarde-sur-Valserine (French pronunciation: [bɛlɡaʁd syʁ valsəʁin], literally Bellegarde on Valserine; Arpitan: Bèlagouârda) is a former commune in the Ain department in the Auvergne-Rhône-Alpes region in Eastern France. On 1 January 2019, it was merged into the new commune of Valserhône.

The river Valserine (French pronunciation: [valsəʁin]) is a tributary of the Rhône that flows for 47.6 kilometres (29.6 mi) from the Col de la Faucille in the Jura Mountains to its confluence with the Rhône at Bellegarde-sur-Valserine. The Valserine Valley has great charm; it includes the Pont des Pierres that spans the river between Montanges and Mulaz (in the commune of Confort), as well as the Pertes de la Valserine just north of Bellegarde-sur-Valserine, a canyon in which during the dry season the Valserine runs underground. As the river flows through the village of Mijoux, it marks the border between Ain (a department in the Auvergne-Rhône-Alpes region) and Jura (in Bourgogne-Franche-Comté).

The Perte du Rhône (Loss of the Rhône) is a sixty-metre-deep geologic fault just upstream of Bellegarde-sur-Valserine in France, into which the Rhône River used to disappear during the dry season. It marked the border between Ain and Haute-Savoie. In 1948, the Génissiat Dam, designed by French architects Albert Laprade and Léon Bazin, was built to the south of Bellegarde. With the construction of the dam, the Perte du Rhône was transformed into a reservoir twenty three kilometres long, from Génissiat to the Swiss border. A similar feature called Pertes de la Valserine still exists in the same area.In 1854, Eugène Renevier, Professor of Geology and Paleontology at the University of Lausanne, wrote Fossiles du terrain aptien de la Perte-du-Rhône with François Jules Pictet de la Rive.

Lancrans (French pronunciation: [lɑ̃kʁɑ̃]; Arpitan: Lancrens) is a former commune in the Ain department in the Auvergne-Rhône-Alpes region in Eastern France. On 1 January 2019, it was merged into the new commune of Valserhône. In 1858, Vanchy (renamed Coupy in 1907, merged in 1966 into Bellegarde-sur-Valserine) and Confort separated from Lancrans to form new communes.
