In June 2005 Steve House and Marko Prezelj climbed a new route on Cayesh, an 18,765 peak in the Cordillera Blanca of Peru. The new route on the west face was completed in 16:30 roundtrip from the glacier. The climbing on this 11-pitch route was uncertain from start to summit: The initial 450 feet of an ice/snow couloir was followed by eleven steep pitches of mixed climbing (M7+), one pitch of pure rock (5.10 at 18,000 feet) and a last pitch of ice/snow that led to the corniced summit.
