Altitude weather delta

High 4,125 m minus low 1,543 m is 2,582 m of relief on this record. A standard tropospheric lapse of 6.5 °C per 1,000 m implies about 16.8 °C cooler at the high point than the valley, all else equal.

That is a model (International Standard Atmosphere environmental lapse), not a forecast and not a trail-closure. Wind, snow, and storms stay in Hazards.

Where the walking ends

This record covers the walk to Annapurna Base Camp / Sanctuary (4,130 m). Beyond that, the continuation is mountaineering, which we do not map as a trail — it needs ropes and high-camp mountaineering on Annapurna I — not a trail.

Ingested from OpenStreetMap relation 17548991 (ODbL). The mapped line is that geometry. Distance, ascent, descent, and high/low points are the Wave N evidence-sheet figures (adjudicated 2026-09-21). Permits are official-sourced; geometry stays OSM-provisional. Water was not mapped to named WaterSource points.

OSM 2D length is 23.88 km (OSM line, ODbL, relation 17548991, lastVerified 2026-09-21). Provisional — OSM line, no official kilometre.

Distance stays provisional. ⚠ secondary: operator itineraries cite about 115 km. Cited km is not this DataPoint. Sanctuary corridor (Chhomrong–ABC), not the full Nayapul roadhead.
