The Wave

Start crouched under the roof with your left hand on an incut edge and right hand on the nose / arete. Go left to the seam and top out straight up (or out left). The guidebook

says

top out left via the seam, though the line drawn in the picture goes straight up. Don't think your choice will affect the difficulty.

Starting with your right hand lower on the arete is also possible. I watched a friend do this variation, though I never tried.

Around the corner from the Jewel.
