Higher ground turns first, so the slopes above the road lead the valley by a few days.
Weather Hard frost Wednesday night. Peak may come early and go fast.
No new reports from the ground here this week.

Around Mount Massive Wilderness Lake County holds most of the wilderness and is just past peak today. Pitkin County, to the west, is 10 days behind.By elevation The wilderness runs from about 10,116 to 13,248 feet. That’s 4 days of season between the top and the bottom: the high stands peak around Sep 18, the low ground holds until about Sep 18, and the color comes downhill in between. The date at the top of this page is the 11,000 to 12,000 foot band.

That’s 3 days later than our model alone would say. This September has been running warm, which shifts peak color.

Also named across Colorado, outside what the canopy read measures here: Rocky Mountain Maple.
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
