Torrent de la Roizonne

The Vaunoire torrent springs in Grand Armet Glacier, 2200m high, and collects small meltwater or regular streams running down from Taillefer, Armet and Tabor ranges.
When it is a little bit dried up, the river disappears into the ground and gets out a little further under Roizonne name. This resurgence is a little before Lavaldens village, after the "rocky rock" as it is called.
