The climb can run anywhere up the face of the rock. The quartz knobs are plentiful, but very slick and difficult to hold or stick a foot on.
Follow the Billy goat trail to the right and turn left at a small bridge (the approach trail is obvious). Making the left puts you at the base of the rock. Jane's Face is immediately after a chimney - it's not very far past the bridge/turn.
Natural anchors at the top. Several trees and flakes are available. You'll need 40-50 ft of fixed rope and 20-30 ft webbing for anchors.
