To the left of the green lichen wall is a semi-cave with a blocky roof. Climb the down-sloping shelves to the left of the roof, stretch or leap to the roof itself, swinging to the far right wall and pull the roof. Finish through another overhanging section to a lichen-coated ramp. Holds inside the cave can be very slimy - not wet, but slimy. A fall while still inside the cave can result in hitting the ground due to rope length and stretch. Helmet highly recommended. Watch the rope carefully - lots of sharp edges.
Great tree anchors about 20 feet from the edge.
