Rockfax Description
II, 350m, 3 - 4 hours. The ambience on this route is incredible, with hanging seracs nearby (and occasionally overhead) throughout. Potential serac fall is a real danger at times so check on conditions before you go and get a pre-dawn start.
1) Climb the 50 degree snow slope then avoid the island of rock by passing it to the left via a step which kicks up to 65 degrees.
2) Stay on the snow slope, between the rocky left-hand edge of the Triangle, and the seracs, choosing the line least exposed to potential serac fall.
3) Level with the top of the Contamine-Grisolle there is often a steepening, formed between the final serac and the rock of the Triangle. It rarely exceeds 70 degrees but is the crux of the route when at its steepest. Continue easily up the snow slope to reach the top of the Triangle. © Rockfax
UKC Logbook Description
Graded AD- in the Alpine Club guide but IV,2 in the Snow, ice, and mixed guide (around D/D+ equivalent). Crux is a (slightly loose) 65 degree section beneath the serac at 1/3 height (which may possibly be harder than when originally graded AD-) and the Snow, ice, and mixed grade is probably closer to the mark.
