II, 350m, 3 - 4 hours. A worthwhile day out which is relatively quiet compared to its neighbours, but suffers from stonefall in hot, dry conditions.
1) Start on the left toe of the buttress and climb 45 degree snow to reach a steeper mixed band, then follow this to reach a second snow ramp.
2) Climb the snow ramp rightwards to mixed ground where the route almost reaches the Contamine-Grisolle.
3) Stay left of that route and climb the thin, icy ramp which takes you to a final rocky ridge and junction with Contamine-Négri on the snow slope leading to the summit of the Triangle.
Follow the Contamine-Négri to the top of the Triangle. © Rockfax
