Climb the blank slab 20 feet up with very little protection. After placing your first piece wander to the arete on the right and head to the top of the block. This gives access to a second face. Use the two diagonal cracks which leads to a small ledge. Use the crack in the corner to finish.

Follow the crack on the slab up to the blocky roof. From here use the slightly overgrown holds to reach the anchor chains. This climb is said to verify whether you climb 5.8 or not, hence the name "Lie Detector."
