Haunting Darkness

When lowering off of Hedwig's Haunt you lower right down this line. It would be a squeeze if it got bolted but it is pretty fun and worth describing. Climb the big obvious crack/flake starting at the base of Spring Song up and to the left. Mantle up so your feet are in the crack and delicately make your way up and left meeting up with the anchor and maybe the last few moves of Hedwig's.
