Primary Hazards
Fall on Tentu La 75–80° ice slope
Rockfall on loose approach gullies
AMS at ABC
Weather trap at Advance Camp
AMS Protocol
Rotation cycle to ABC and back to BC is critical. Do not commit to summit attempt without completing rotation.

Descend immediately if reading drops below this at rest
Diamox (Acetazolamide)
Recommended
Crucial due to rapid vehicle ascent to 15,000ft.
⚠️ Golden Rule: Immediate drive down to Keylong.

Near Misses
5
logged
We have analysed 6 documented incidents for this expedition to extract critical safety lessons.
Due to the nature of mountaineering — where most non-fatal incidents go unreported — experts estimate 30+ total historical incidents on this route. Estimated historical fatalities: 4. We present the documented record as-is rather than speculate on undocumented cases.
Year
2021
Exhaustion / Overexertion
Outcome
Assisted descent by team
Contributing Cause
Overambitious schedule and insufficient turnaround discipline
Key Safety Lesson
Always melting snow takes time. Always carry a stove system capable of rapid boiling.
Year
2020
Fall — Snow/Ice
Outcome
Self-recovered
Contributing Cause
Crampon slip on steep ice, inadequate self-arrest technique
Key Safety Lesson
Always constant tension on the rope and immediate self-arrest skills save lives on steep slopes.
Year
2018
Fall — Snow/Ice
Outcome
Self-recovered
Contributing Cause
Crampon slip on steep ice, inadequate self-arrest technique
Key Safety Lesson
Stay well back from the ridge edge. Cornices can break much further back than expected.
Year
2017
HACE — High Altitude Cerebral Edema
Outcome
Assisted descent by team
Contributing Cause
Continued ascent despite severe AMS symptoms
Key Safety Lesson
Always acclimatization cannot be rushed. Do not ignore severe headaches.
Year
2016
Hypothermia
Outcome
Hospitalization
Contributing Cause
Contributing factors not fully documented
Key Safety Lesson
Always the Tentu Pass approach is brutal. Premium expedition gear is required to survive a sudden whiteout.
Year
2015
Avalanche
Outcome
Self-recovered
Contributing Cause
Poor campsite selection in avalanche runout zone
Key Safety Lesson
Always avalanche danger isn't just on the route. Site selection for BC is critical.
Source: Public Records / News Reports
Why estimates differ from records: IMF and news sources only capture permitted expeditions and helicopter rescues. Non-fatal near-misses (AMS, frostbite, falls with self-rescue) are almost never filed. Peaks with multi-decade climbing histories compound these gaps significantly.
Emergency Contacts
Evacuation Route
Retreat to Beas Kund Base Camp. Trek to Dhundi for vehicle evacuation to Manali hospital.
Solo Advisory
Solo climbing is highly dangerous and not possible. Technical glacier travel, crevasse navigation, and steep ice climbing require a certified rope team.
