Sistema de Creenicas Sport route 9b 1
Sisu Project Boulder problem 9B (approx) 1

The Sisu project is an unclimbed line in Finland first tried by Nalle Hukkataival. It is incredibly hard: Nalle was only able to do a handful of the moves over the course of many sessions.

Hamish McArthur:

I would say it's physically possible, but practically impossible, maybe. Physically, I believe that a human being has the physical capacity to climb the thing, but I think you'd have to really, really, really value climbing that and only live there essentially and have that be your entire life goal. The thing that really brought it home is feeling some of the holds, how small and sharp they are, and knowing that if I had one go or I tried as hard as I possibly could, I would go through my skin on it. So you could maybe have like one max-effort go a week at best, and that's only a few weeks a year when it's cold enough to do it. So it feels like practically an absolute nightmare to project. [3]

Sitsquatch Boulder problem 8B (approx) 1

The grade is a guess as none was offered by the FA.
Six Degrees Boulder problem 9A+ (approx) 1

The Six Degrees Project is an unclimbed problem in Yosemite. Aidan Roberts made promising links of this during his 2024/25 season.

The problem has also been tried by the likes of Nalle Hukkataival, Jimmy Webb, Dave Graham, Carlo Traversi and Keenan Takahashi.

Aidan Roberts:

A series of slashed edges trend leftwards up a scooped face. The holds were bad, but the feet were worse. With nothing to offer any opposition, the only options seemingly to contort into some brutally shouldery positions until you can will yourself to fly to the lip. [1]
