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
Road evacuation via jeep to Spello/Pooh clinics. ITBP helipad at Lambar for military extraction.
