Tom Randall made the first free ascent of the boulder in August 2015, giving it a grade of V13 (8B).

The crux of the move requires backhanding a mono, allowing you to spin your feet around to jam them into a perpendicular crack, pointing out of the cave.

The final section of roof crack consists of thin hand jams and monos, which are easy to fall off if the climber makes a mistake.

Once they have reached the edge of the cave, the climber finishes by climbing over a lip, and grabbing a ledge for the top.

[3][4] Randall said of the climb "I don't have any doubts about it being the hardest crack boulder problem in the world, at all.
