Val d'Hérens

Val d'Hérens is an alpine valley in the Valais canton of Switzerland.

It was formed by the Hérens glacier, which retreated at the end of the last ice age.

It is now the valley of the Borgne river, a tributary of the Rhone (confluence above Sion).

It extends from the Rhône valley to a number of high mountains - Dent Blanche, Dent d'Hérens, Mont Collon, Mont Blanc de Cheilon.

The area has two mountain peaks over 4,000 metres in altitude: la Dent Blanche ("white tooth") at 4,357 m, and la Dent d'Hérens ("Hérens tooth") at 4,171m.
