Traverse Safety & Risk
Chobia Pass Expedition — Safety Guide
Altitude physiology, pass crossing go/no-go criteria, evacuation protocol, and insurance requirements.
Primary Hazards
Falling deep into an unmarked crevasse
HAPE / HACE at 16,000+ ft
Freezing to death if trapped in a whiteout on the pass
AMS Protocol
Extremely high risk. Pushing above 16,000 ft demands extreme respect.
Altitude Physiology — SpO₂ by Camp

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
2022
Lost / Navigation Failure
Outcome
Rescue by external team
Contributing Cause
Contributing factors not fully documented
Key Safety Lesson
Do not blindly follow sheep trails. Always use a calibrated compass and GPS.
Year
2021
Weather Stranding
Outcome
Self-recovered
Contributing Cause
Contributing factors not fully documented
Key Safety Lesson
Always pitch tents at least 50 meters above the riverbed to avoid sudden glacial surges.
Year
2020
HAPE — High Altitude Pulmonary Edema
Outcome
Assisted descent by team
Contributing Cause
Rapid ascent without adequate rest days
Key Safety Lesson
Always hAPE can strike suddenly. The only cure is immediate descent, regardless of the time of day.
Year
2017
Fall — Rocky Terrain
Outcome
Self-recovered
Contributing Cause
Loose scree and insufficient footwear traction
Key Safety Lesson
Always cross the final gully before 9 AM to minimize rockfall risk from melting ice.
Year
2016
River Crossing Incident
Outcome
Rescue by external team
Contributing Cause
Contributing factors not fully documented
Key Safety Lesson
Always glacial melt doubles river volume by afternoon. Cross all major streams before 9 AM.
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
Extremely difficult. Manual hauling down to Alyas is the only way off the upper mountain.
Solo Advisory
Absolutely prohibited under all circumstances.
