Keystone Grooves 15

Mostly pleasant climbing on good rock with a delicate crux. Takes the obvious line of grooves left of Cornerstone Rib, but fails to gain the obvious summit gullies. Left of Cornerstone Rib is a gully. Between this and the corner where Diagonal Route starts is a big groove that leans leftwards.

1. 45m Up the groove and gully. Belay where the gully opens out.

2. 25m (crux) Left and climb the corner, then a delicate 5m traverse left into the next corner.

3. 45m Up, right behind a big loose block, right again and climb left-slanting grooves to below a slab.

4. 35m Ascend the beaut slab to a bushy ledge beside Cornerstone Rib (possibly the ‘green pocket’ on Cornerstone Variant) - old bent bolt above here, below hard climbing into summit gullies.

5. 10m Move right onto Cornerstone Rib and up to platform.

6. 45m Continue up the Rib.

The topo is a guess. Please update.
