The boulder down and left of problem 4 in the nwb guide. Sit down start at the left hand end of the sloping holds. Heel hook across and make a long reach round the arete to the break. Follow this to the very end before slapping out right to the top of the boulder. Follow the top to mantle out round the arete. No use of the rock underneath. Sorry if its been done before.
