★★ Big Boris (old-school version) 18

A good climb - interesting and varied. Start below blocks leaning against the face four metres left of 'Hermes'.

1. 25 metres - A bit harder now the top block has gone. Up the blocks, then an awkward move to gain a crack. Continue up a ramp to a ledge. Scary climbing up the slab above; leftwards at first then straight up to belay in the chimney.

2. 30 metres - Up the chimney past some dubious rock and a large wedged flake to a niche on the left. A short V-corner leads to a large ledge.

3. 35 metres - Climb to the top of a huge triangular leaning flake with some trepidation, then step onto the face and continue up scoops to the top of the Fearon block. Finish as for 'Fearon'.

The ethic at Booroomba is generally staunchly traditional. Most climbing goes either entirely on gear or gear with bolts for those walls where there is insufficient gear to protect climbs. Climbs are occasionally rebolted, but retro-bolting would be considered vandalism of the lowest order.
