Tactical & Camp Notes
Requires master-level crack climbing and jam skills, efficient big-wall hauling, lightning-fast ropework during fleeting Patagonian weather windows, and expert rappel setups.
Identified Objective Hazards
- •Fierce Patagonian storms (Roaring Forties) producing sudden hurricane-force winds and icing
- •Falling verglas and rockfall down the access couloirs during afternoon warming
- •Extreme wind gusts capable of pinning climbers against rock and jamming rappel ropes
- •Severely limited good weather windows requiring rapid ascent and retreat
