That’s 11 days of season between the top and the bottom: the high stands peak around Sep 25, the low ground holds until about Oct 6, and the color comes downhill in between. The date at the top of this page is the 9,000 to 10,000 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 3 days later than our model alone would say. This September has been running warm, which shifts peak color.

Colorado aspens are the main event, turning entire mountainsides gold and amber while Gambel oaks add russet and orange at lower elevations and cottonwoods line the rivers in yellow.

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
