Start up in the corner to the left of the slabby face. After the third or fourth bolt leave the relative comfort of the wide corner crack and transition onto the face. Climb up and right through occasionally tenuous moves to a narrow ledge on the arete at the right of the slabby face.
Make a move or two upward into the steepening territory above you and get established on the arete. Move quickly as the pump starts to build and follow the arete up and left, with a bit of footwork and muscle required right at the end.
On the right section of the north-facing main wall this line starts in the corner and heads across the face to the arete.
12 bolts, anchors.
