Walker's Haute Route

Curated schematic from named OpenStreetMap nodes (ODbL). The line is pin-to-pin, not a walking path. 2-D length is labelled schematic — not walking distance. Ascent, descent, and high/low points are Copernicus GLO-30 samples at those vertices only (copernicus-dem:glo-30) and remain provisional. Water, permits, and hazards were not taken from OSM tags and must be verified.

No single connected Walker's Haute Route hiking relation resolved on 2026-08-25 (Nominatim empty; not the glaciated ski Haute Route). Geometry is an ordered pin-to-pin line through OSM-resolved named nodes: Chamonix-Mont-Blanc → Argentière → Trient → Champex-Lac → Le Châble → Cabane Mont Fort → Cabane de Prafleuri → Arolla → Les Haudères → La Sage → Cabane de Moiry → Zinal → Gruben → Sankt Niklaus → Grächen → Zermatt. 2-D length 122.6 km is schematic — not walking distance. Published ~200–221 km / 13–14 days are cross-checks only, not this DataPoint. osmRelationId is unset. Never graduate to verified without a single connected OSM hiking relation.

Every listed waypoint resolved to a named OSM node this pass. Grächen is on the ordered list (St. Niklaus → Grächen → Zermatt); that jog is pin-to-pin, not a claimed walking detour.

typicalDays 14 is the recognised typical hut-to-hut itinerary — typical, not an official duration statute. Published windows are about 13–14 days; that stamp is not this DataPoint. bestSeason is left unverified (a mid-July–mid-September window is widely described; it was not copied from an official SAC statute this pass).

GLO-30 high 2,822 m is under published Col-stage ~2,987 m — a 16-vertex schematic sample, not the pass itself. High point left as Copernicus, not overwritten. Cumulative DEM ascent 4,314 m is an under-count versus published walking gain on the order of 14,000 m; do not treat it as that figure.

Water was not mapped to named WaterSource points (no honest atFraction). Huts and villages exist; they were not positioned from an official named list this pass.
