What these numbers describe

Historical climate at one selected model cell. Higher routes, sheltered valleys and exposed ridges can differ substantially.

How to read these figures

Selected cell: 63.7, -149.3 · official Denali Savage River trail candidate cell

The candidate model cell intersects the official NPS Savage Canyon Trail geometry and replaces a permanent-snow cell near the Denali massif. Full 1991-2020 climate validation remains required before approval.

Temperature sampling window (local time, limited to daylight): 08:00–18:00.

A wet day has at least 1 mm of total precipitation (including snow water equivalent). It may rain for only part of the day.

A snow day meets either model threshold: 10% snow cover or 2 cm snow depth.
