★★ Determinant (original) 15

A wandering climb with a good, exposed slab on the second pitch. Start 25 metres left and down from 'Hermes' at the biggest tree around. 'Terminant Corner' is now the accepted way to finish.

1. 20m (15) Climb the easy slab, keeping to the right, to a large bushy ledge (or just walk up the manky ramp on the right to the belay!)

2. 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.

3. 20m (12) Climb the right-hand side of the block above the rap station, then traverse right along the break and up a narrow slab to a tree belay.

4. 26m Walk on up the slab and chossy ledge.

5. 28m (15) Ascend a wide groove down and left from the imposing corner crack ('Terminant Corner'). Move left across a small slab and pull up onto a ledge.

6. 20m (15) Up and step onto the rib on the left. Cruise to the top.

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.
