Aiguille Extra, South Face, Previously Unreported. Peter Noebels and I climbed the South Face (IV 5.10c, 1,400') of Aiguille Extra in July, 1993. This route is a beautiful climb with excellent crack climbing and clean rock. The climb begins on a ramp right of the snow chute. It ascends crack systems just left of a large diagonaling overhang. Climb the ramp and ledges to the base of a right-facing book.
