Ingested from OpenStreetMap relation 1244828 (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 335.8 km (relation 1244828; ref=JMT, OSM distance=343.9 km, roundtrip=no, Wikidata Q967917). JMT relation members only — the Pacific Crest Trail was not fetched. NPS cites 211 miles Yosemite Valley to Mount Whitney (https://www.nps.gov/yose/planyourvisit/jmt.htm, checked 2026-08-25); that figure is a cross-check only, not this DataPoint. OSM start is Happy Isles; OSM end is the Whitney summit area.
typicalDays 21 is a published ~3-week window, not a DataPoint. NPS wilderness permit reservations run late April through October (https://www.nps.gov/yose/planyourvisit/wildpermits.htm, checked 2026-08-25); snow on high passes is not dated as a walking season on that page.
DEM high 4,408 m is 13 m under Mt Whitney 4,421 m — the summit was sampled, not a truncated valley line. High point left as Copernicus.
Water was not mapped to named WaterSource points (no honest atFraction). Sierra streams are frequent on published descriptions; treat as required. They were not positioned from an official named list this pass.
