Higher ground turns first, so the slopes above the road lead the valley by a few days.
Weather Wind to 40 mph Friday. Color may come down before it turns.
Weather Hard frost Saturday night. Peak may come early and go fast.
No new reports from the ground here this week.

Height off 3DEP inside the wilderness’s own boundary; each band carries the date our model gives that elevation, corrections and all. The percentage is how much of the wilderness stands in it.
That’s 1 day later than our model alone would say. This September has been running warm, which shifts peak color.
Plan this tripIf you can only come on certain days
Set the days you can be here. Everything under them answers for those days, not for peak.
Wednesday 16 September to Thursday 17 September
You’ll find it just past peak up high, nearly peak lower down.
Up at 8,000 feet the stands peak around Sep 9; down at 7,000 feet they hold on until about Sep 21. Pick your elevation for the day you come.

Also named across Montana, outside what the canopy read measures here: Western Larch, Paper Birch.
Montana's fall is a two-act show: aspens and cottonwoods turn gold around 17 Sep, then western larches steal the finale in mid-October, turning entire mountain slopes amber before dropping their needles.
This forecast is built from the species that stand here, their elevation and this September’s weather, and corrected in season by cameras, foresters and our own crew. Out here we score it against NASA's satellite record of when the canopy shuts down, read inside each unit’s own boundary: two dates in three land within 12 days of it. How this map is made
