First ascent.
Featured in the classic climbing movie Dosage 4, where Courtney Hemphill comes very close to sending and takes some scary falls from high up. Its one of the most impressive slab lines I’ve ever seen and sits in a beautiful picturesque surrounding, just next to ‘Kings of Sonierto’ and ‘Off the Wagon’. I found a really nice sequence and luckily did not take a fall from the top:) To my knowledge, nobody else has done it before (please correct me if I’m wrong), so it might be a first ascent. As it took me roughly the same amount of time like the classic Fontainebleau slab ‘Duel’ (though it climbs quite differently), I would estimate the difficulty to be in the same range. That is VERY difficult to say though, as its even less powerful than Duel; there is not a single move that is physically hard. Just very sustained, insecure, technical climbing on bad footholds. On the whole climb you are never standing in a relaxed position, as I could only weight the footholds for a few second before they would start slipping. You really have to be focused and stay calm until the very (high) top, where without a handhold that deserves that name I had to stretch/tiptoe on a smeary foot to be just able to reach an edge, which you can use to jump to the rescuing top lip. Whatever the difficulty might be, its definitely one of my favorite problems ever and one I’m really proud of!
