Sentry Box

Start in the groove about two metres left of “Mars Attacks”, easy first clip. Dynamic or reachy moves lead to a huge jug and the second bolt. Awkward moves round the bulge on small holds get you to the third bolt and some sloping holds. Move right then up to gain a sort of rest in a short sentry box, bolt runner. Swing out right onto the arete and move up on good holds to the bulging black roof and two more bolt placements. Strenuous moves over the bulge on the left get you onto the hanging slab and a move right leads to the belay of “Mars Attacks”. Tony Burnell
