Triple-A Michigan says trees in some sections of the Upper Peninsula are showing as much as 35 percent color on the first day of fall.
The auto club takes a weekly survey of state parks and visitors' bureaus. It says peak color is about two weeks away in the UP and won't reach the state's central and southern regions until mid-October.
The most vivid colors this week can be found in Porcupine Mountain State Park near Ontonagon, Van Riper State Park near Ishpeming, Indian Lake State Park near Manistique, and McCain State Park near Calumet.
Color development is around ten percent in the Gaylord and Cadillac areas.
