Third ascent.

3rd Ascent. Hardest boulder I have done and 100 % my style. I think Giuliano [Cameroni] was correct on the grade. Crimp testpiece.

Hard 8C or low 8C+ IMO. It's like Jade or Hazel Grace but 2 grades harder!

Needs crazy perfect sticky damp conditions and I got them today. Physically not the hardest move I’ve done on crimps by itself but the fact the hard move is the last makes it crazy hard.

The temperature, humidity, wind, and skin all need to line up perfectly when arriving at the crux. It renders the bloc nails hard and you get 2/3 goes max once a week.... ouffff

Still two grades harder than Dreamtime whatever that means…. Time will tell. [1]

Second ascent. 2 sessions.

2ème ascension. FA Charles Albert. Almost in a session then first try second.... So much in my style I can't grade it... Similar to New Base Line or Hazel Grace in difficulty... [1]
