★★★ Determinant (extended) 15

A wandering climb with a good exposed slab and a classic crack finish ('Terminant Corner'). Start where the track first touches the 'nose' of the cliff, at a short steep-looking hand crack with two smaller ones either side.

1. 20m (15) Up the short crack to a ledge. More easily to the base of a slab split by a thin crack straight ahead and a wider one further left. Step left into the left-facing layback crack. Up this to belay on the large bushy ledge.

2. 20m (15) Climb the short corner behind the tree. Up the slab with gear in horizontal breaks out right, then a bolt up high, to gain another large ledge (the top of the original route's first pitch).

3. 30m (15) From the left side of the ledge move left across the slab (crux), then up and left to a short corner crack to 'The Prow'. Belay on gear or the rap station at the left side of 'The Prow'. Climb straight up off the belay on very easy ground to get good high protection for the slab.

4. 55m (12) Climb the right-hand side of the block above the rap station, then traverse right along the break and up a narrow slab. Continue easily up the bushy ramp to tree belay below the prominent corner.

5. 35m (15) Up the corner crack. Head left to avoid the lichen-filled wide crack, step up a level then back right to finish with a step across the void.

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.
