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 14+ total historical incidents on this route. Estimated historical fatalities: 2. We present the documented record as-is rather than speculate on undocumented cases.
Year
2022
Snow Blindness
Outcome
Led out by team members
Contributing Cause
UV-protective eyewear not worn on high snowfields
Key Safety Lesson
Always uV radiation on high-altitude snowfields is intense. Wear Category 4 sunglasses constantly.
Year
2019
Fall — Rocky Terrain
Outcome
Self-recovered
Contributing Cause
Loose scree and insufficient footwear traction

Always move quickly and quietly through steep gorges. Helmets must be worn at all times.
Year
2017
Crevasse Fall
Outcome
Rescue by external team
Contributing Cause
Contributing factors not fully documented

Year
2016
Fall — Rocky Terrain
Outcome
Self-recovered

Year
2015
Fall — Rocky Terrain
Outcome
Medical treatment at base camp
Contributing Cause

Self-recovered
Contributing Cause
Contributing factors not fully documented
Key Safety Lesson
Always treat your support staff with extreme respect. They are your lifeline.
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
Mule or manual carry to Rilkot road-roadhead (currently under construction) or ITBP Helipads.
