Higher ground turns first, so the slopes above the road lead the valley by a few days.

Around Jedediah Smith Wilderness Nearly all of the wilderness is in Teton County, which is peak color today.By elevation The wilderness runs from about 6,685 to 9,884 feet. That’s 23 days of season between the top and the bottom: the high stands peak around Sep 9, the low ground holds until about Sep 27, and the color comes downhill in between. The date at the top of this page is the 6,000 to 7,000 foot band.

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.
Set the days you can be here. Everything under them answers for those days, not for peak.

The Tetons rising above the golden cottonwoods of the Snake River flats is one of the most famous fall landscapes in the American West, and the aspen groves at elevation add hillsides of gold.
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
