L1 – You follow a slab of ice before you reach the gully. Stand on ice.
L2 – A narrow gully on ice with the crux of passing all the metal wires. A nice pitch :). Stand on ice.
L3 – Final pitch and offers a lot of nice variations. Stand on a tree. It is the photocover of the Heavy water guide book :).
Note: Do the abseil on the left wall from some trees if there are people below.
