Tactical & Camp Notes
Demands master-level mixed climbing ability, absolute psychological commitment, expert placement of ice screws in thin water ice, and hanging sit-bivouacs.
Identified Objective Hazards
- •Continuous spindrift avalanches cascading down the narrow central ice couloirs
- •Fragile, brittle water ice offering questionable protection for ice screws
- •Unrelenting vertical steepness preventing safe retreat down the 1,500-metre wall
- •Severe sub-zero Himalayan storms bringing whiteouts and rapid frostbite risks
Historical Context
Pioneered in April 2002 by Mick Fowler and Paul Ramsden in an eight-day round trip, winning the inaugural 2003 Piolet d'Or award.
