Right couloir of Saint Pères

The steepest and most esthetic (a good 50 degrees for the first 100 m and 2-3 m wide for the first 30 m) and slightly S-shaped the end of the slope is hidden, when watched from above, crating quite an atmosphere, an atmosphere reinforced by l’Arête des Saint Pères which, blocking the sun, maintains the couloir in the shade almost throughout the entire day and season.
