Traill's Pass Expedition/ 76
Rope Ascenders
Caution
You must be highly proficient with a jumar (ascender). You will be hauling your own body weight up a frozen vertical ice wall at 17,000 ft in the dark.
Terrain Breakdown
Extreme. You are walking on shifting glaciers, jumping over hidden crevasses, and ascending 60+ degree ice walls using ropes.
Summit Day Notes
A 12-to-15 hour brutal slog starting at 1:00 AM. 17,427 ft altitude strips your oxygen while the massive physical exertion of climbing ice drains you entirely.
The Descent
Rappelling down the eastern face of the pass into Lawan is often more dangerous than the climb, as exhaustion leads to fatal rope handling mistakes.
Preparation
Requires elite mountaineering fitness, technical rock/ice climbing familiarity, and extensive high-altitude exposure.

Highly volatile. You climb consistently but the real danger is sleeping at 14,500 and 15,800 on solid ice where your body recovers terribly slowly.

Turnaround Threshold: Below 70% SpO2 at rest.
Key Risks
Crevasse falls on Pindari icefall
Avalanches on the pass approach
Severe HAPE/HACE
Frostbite on Camp 2
AMS (Altitude Sickness)
Extreme danger. You are sleeping at 15,800 ft on solid ice before pushing to 17,400 ft.
Evacuation Route
Effectively non-existent above Camp 1. If you break your leg on the icefall, you must be lowered down via rope by your team. Helicopters struggle greatly with the winds above Pindari.
Solo Trekking
Suicidal. The descent requires fixing ropes and the Pindari glacier is heavily crevassed.
Common Trail Ailments
🏥 Nearest ICU: Haldwani
Tactical Emergency Hub
> Evacuation ON the glacier requires highly technical rope lowering by the team. Helicopters cannot safely hover at Traill's pass.
