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.

Descend immediately if reading drops below this at rest
Diamox (Acetazolamide)
Recommended
125mg twice daily starting at Paton.
⚠️ Golden Rule: Immediate descent upon ataxia or resting shortness of breath.
Expedition Medical Kit
AMS Protocol
Sustained extreme altitude makes AMS monitoring critical.
Emergency Contacts
Evacuation Route
Stretcher carry to Munsiyari or Dharchula. Heli-evac is highly unreliable.
Solo Advisory
Solo trekking is strongly discouraged. It involves crossing remote glaciers, boulder-strewn landscapes, and requires Uttarakhand Forest Department permits that are difficult for individuals to obtain.
