Ingested from OpenStreetMap relation 20103066 (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.
