Excellent Haycock compression problem. Your right hand is low on a crimp under the overhang in the seam out right, your left on a good edge on the arete. Follow a few faint sloping edges on the seam and work you way out and up the arete.
Careful not to dab on the ground boulder that is awkwardly placed directly under the start.
From the Caves/Top Rock trail split, this is only a few yards up the Top Rock trail on the right hand side. You will see the back of this boulder just a few yards from the trail. If there is chalk on this boulder, you should easily spot the faint sloping crimps on the arete.
Several pads. A large ground boulder makes for a bunched start and odd pad placement.
