★★ Possum 13

Short pitches, but packs a lot of climbing in that space. Start below a ledge four metres left of Carezza - just right of a right-facing open corner in the alcove up and left from Aitchison's Needle.

1. 16m The first pitch involves some harder-than-13 moves to get off the deck, then fairly easily upwards and left until you get to a belay on top of the pillar below the traverse.

2. 22m The traverse pitch provides some classic moves and a bit of fun for the second - make sure you place your gear well for those following! Up easily for a few metres then head right to a big grassy ledge (take your pick for belay).

3. 12m Third pitch many take the alternate version (Carezzissima Finish) which goes more direct and at a harder grade. For the original, up the corner at the back of the ledge then a few harder-than-13 moves to get up and over a flake and then easily up and away to finish off.

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.
