Trans-Jammu Traverse

OSM hiking traverse, one intended nwn Chamba→Jammu corridor (275.84 km). Cross-state: ~120 km Himachal (Chamba: Chamera→Kadwah) and ~156 km J&K (Udhampur/Jammu: Kaluni Gala→Panjar). DEM high 2,776 m (mid-hill rollers, not alpine). Provisional for a ~2 km Ramnagar–Resian mapping gap.

The western Himalaya from orbit on the Trans-Jammu Traverse corridor

Figures marked provisional are seed data and still need verification. Source and last-checked date sit under each cited value.

Altitude weather delta

High 2,776 m minus low 533 m is 2,243 m of relief on this record. A standard tropospheric lapse of 6.5 °C per 1,000 m implies about 14.6 °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 13926283 (ODbL). The mapped line is that geometry. Distance, ascent, descent, and high/low points are the Wave I-5 evidence-sheet figures (adjudicated 2026-09-21). Season was not sourced. Member ways are untagged for sac_scale; SAC stays ungraded.

OSM 2D length is 275.84 km (OSM line, ODbL, relation 13926283, lastVerified 2026-09-21). Provisional — OSM line, no cited itinerary. Grok-confirmed one intended nwn traverse, not a superroute of unrelated pages (43 way members, type=route route=hiking, a single east→west corridor of named stages). Cross-state split: ~120 km in Himachal (Chamba: Chamera→Kadwah, tops 2,773 m) and ~156 km in J&K (Udhampur/Jammu: Kaluni Gala→Panjar, low 533 m at the west end). An HP-vs-J&K editorial split is optional later, not required. Ingest used the longest component (280.6 km) and left 0.5 km leftover fragments. The published DataPoint is the evidence-sheet 275.84 km. Stays provisional because of a ~2 km mapping gap between Ramnagar and Resian (the only material break; other gaps are 21–665 m connectors).

typicalDays 23 is Math.round(lengthKm/12), a placeholder. Days are unknown on the evidence sheet and stay provisional.

High 2,776 m is Copernicus GLO-30 (lastVerified 2026-09-21) — resample jitter vs Grok's 2,773 m crest; nothing above 2,800 m was dropped. Foothill max, not a Ladakh pass. Low 533 m is the same DEM resample, verified. Ascent 19,789 m / descent 20,493 m remain provisional DEM (~20 km cumulative gain over 276 km of mid-hill rollers is consistent).

Permit is Unverified (not sourced from OSM or an official tariff; evidence sheet 2026-09-21). Unverified — confirm the regional permit / inner-line requirement before travel. Season is unknown. OSM water context (ODbL, lastVerified 2026-09-21), not a potability or reliability claim and not mapped to WaterSource points (no honest atFraction): +10 springs.
