The Chabrières Oucanes

The Oucanes that can be seen on this walk are strange geological formations that are quite original for the Ecrins massif. The karst that they are made of is thick limestone and dolomite that is part of the Briançon fragment of Chabrières. In a limited space, the Oucanes make it possible to observe the characteristics of alpine karst: limestone pavement, meandering ribs, small rock pools, corridors with ribbed walls and Vaucluse karst springs.
