Follow the dihedral up to a bulge/roof (careful of some loose-looking rock.) Traverse right underneath the bulge and ascend a small corner (crux), then climb a long way on easy terrain to reach the anchors. The view from the top is great - once you're clipped into the anchors, pull up onto the "summit" and enjoy.
Location
Scramble up the gully to the right of Barney Rubble about 15-20 feet, then walk right across the narrow ledge to reach the base of the route. There is a wide spot about halfway out the ledge where you can drop your packs and gear up.
Protection
12 bolts to chains. A 60m rope barely reaches - knot your rope before lowering or rappelling.
Leo Henson and I toproped this rig long time back, should have been a couple of bolts on top. I remember this being a worthy route, glad you guys bolted it up.
