Sirens of Titan

Start as for Prince of Darkness. This is the right-angling crack on the top buttress of the West Ridge. Scramble up to the base of the crack, place one or two big pieces and pull up into the crack. Follow the crack to the arete and then up to a belay ledge. Be careful setting up the belay as the blocks are big but detached. Walk off towards the gully.

Camalots (1, 2, 3, 3.5 and 4) plus a few nuts. Extra #2 and 0.75 Camalots for belay.
