Altitude weather delta
High 1,203 m minus low 287 m is 916 m of relief on this record. A standard tropospheric lapse of 6.5 °C per 1,000 m implies about 6 °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.

Ingested from OpenStreetMap relation 8188414 (ODbL). The mapped line and 2D length are derived from that geometry. Ascent, descent, and high/low points are sampled from Copernicus GLO-30 (copernicus-dem:glo-30) and remain provisional. Water, permits, and hazards were not taken from OSM tags and must be verified.
OSM 2D length is 87.6 km (relation 8188414; network=rwn, operator=Wanderland Schweiz, ref=32). lengthKm is verified: 87.6 km matches the official 87.6 km (https://www.schweizmobil.ch/en/hiking-in-switzerland/route-32; ch.astra.wanderland Route attributes (opendata.swiss langsamverkehr-wanderland-schweiz, dataset 2026-02-25, parsed 2026-09-09)). Official km is the ±3% cross-check, not this DataPoint.
DEM high 1,203 m. GLO-30 cumulative ascent 3,349 m is the same order as the official 3,437 m figure (ch.astra.wanderland Route attributes (opendata.swiss langsamverkehr-wanderland-schweiz, dataset 2026-02-25, parsed 2026-09-09)). High point left as Copernicus.
Water was not mapped to named WaterSource points (no honest atFraction). Villages and inns exist; they were not positioned from an official named list this pass.
