Descend the pocket glacier to the base of the southeast buttress. Climb this buttress, through sandy broken terrain and with poor protection in places in the first ~75m. Above this, the rock improves up a steep yellow slab to a small gendarme. Descend into the notch and climb easier ground above to the summit.
Descend as per the West Ridge (down that route.)

The Challenger is the obvious rising crackline that begins down low in the overhang and rises up to the right into the crack/flare at the right-most end of the Pet Wall.
The must-do line of the area. NMT tackles the spectacular prow on bulletproof rock, the crux is savage but many onsights are thwarted by the higher endurance crux which involves straightforward pulls off full pad crimps with little opportunity to shake out. Stay alert as tricky moves out right guard the anchor.

A direct, well protected line up the buttress that will test your technical skill.
P1: Start just right of the bay below a bolt. Climb face holds and cracks to a ledge and a thin crux gaining the dyke above (3 bolts).
P2. Climb the layback flake to a technical crux when the corner closes. At the top of the flake, gain a ramp back left to an anchor that is shared with S&L (7 bolts).
P3. Climb the sustained, featured slab directly above. When a dyke finally provides some relief, follow it up and right to an anchor (6 bolts).
P4. Continue straight above to a flake and easier climbing. Finish straight up or to the right in the shallow dihedral with "Snakes and Ladders" (4 bolts).
