What the records store
- Annapurna Circuit high-point DataPoint: 5,389 m (Copernicus GLO-30). Wikipedia Thorong La cites 5,416 m — a cross-check, not this DataPoint. The DEM is 31 m under that cited pass and is not overwritten.copernicus-dem:glo-30 · verified 2026-09-24 · demen.wikipedia.org · 2026-08-24
- Everest Base Camp high 5,299 m · Annapurna Base Camp high 4,125 m · Manaslu Circuit high 5,151 m — each figure is the record’s DataPoint, not a pass rename.
AMS — general, not an itinerary
CDC Yellow Book: altitude illness risk rises with sleeping elevation and rate of ascent. Gradual ascent is the usual control. This desk does not invent a Manang rest day, a night-by-night schedule, or a drug protocol.wwwnc.cdc.gov · 2026-09-10
The Circuit record already lists altitude illness at Thorong La (5,416 m) as a hazard. That line stays a cited pass name; the stored high remains the DEM.
