- Bolting
- Cleaned and rebolted by VTNO in summer 2019 as a combination of Uxgloa, the original 1966 Conod-Clère and Concept de l'angoisse; 14 quickdraws and no nuts or cams needed. Some belays are two unlinked bolts (R2 and R3) while the upper ones are chained, and a 2022 party found the protection partly mixed bolts and pegs. Bolts are close on the hard pitches but you climb between them on the 6a and 6b ground, with an engaging finish to pitch 2.
- History
- First climbed on 16 and 17 May 1966 by Bernard Conod and Jean-Paul Clère. Cleaned, re-equipped and re-routed as 'Conod-Clère revisitée' by VTNO in summer 2019.
