When to see fall color in Wasatch
Wasatch slopes mix aspens with red mountain maple and vary sharply with elevation.
Typical planning window · not a live leaf reading
September 19–October 12
Approximate historical planning range. Actual peak depends on species, elevation, drought, temperature, and storms.

Historical satellite autumn timing
Checking USA-NPN historical greendown…
The satellite record measures the typical midpoint of landscape greenness decline; it is not a measured date of colorful foliage peak.
PhenoCam canopy timing: historical validation
Checking nearby calibrated forest cameras…
Historical camera greendown trends are evaluated out of sample before an offset can be displayed. This does not alter the scenic peak forecast.

Recent local leaf-color observations can corroborate season progression, but do not represent a forest-wide percentage.
Best 3 fall color drives
Select a corridor, then compare elevation and check official access notices before setting out. Drive names and descriptions are route guidance, not live road condition reports.
DRIVE 1
Alpine Loop Scenic Byway
American Fork to Provo Canyon
Seasonal closures possible
DRIVE 2
Guardsman Pass
Park City to Big Cottonwood Canyon
Steep weather-sensitive pass
DRIVE 3
Mirror Lake Highway / UT-150
Kamas toward Mirror Lake
Higher elevation color and weather
Access not verified: Park entrances, shuttles, reservations, seasonal road closures and trail access must be checked with the responsible agency. NWS weather cannot confirm roads are open.

Forecast samples one representative location (40.56°, -111.67°). Mountain passes and coastlines may have very different weather. This is weather information, not a live foliage measurement.

Where to go next
How this outlook works
The regional seasonal model shares the basic approach of the Michigan fall color tools: timing first, weather as a trip-planning input. The national weather feed uses NWS data; current colored-leaf reports, when available, come from volunteer observations at nearby sites. Neither source measures a regional leaf-color percentage. The broad seasonal window is editorial planning guidance and should be checked against local reports.
