Colorado Fall Colors Begin

Here in southwest Colorado the summer heat broke about a week ago. Instead of high 80s F. during the day, it’s high 70s and of down into the 40s at night. Beautiful.

And perfect for the fall colors in the high country to progress slowly and steadily. So I went up into the San Juan National Forest the other day to check them out.

At Trout Lake, my personal benchmark because of the combination of beautiful lake, awesome mountain peaks, and aspen forests, it was just beginning. Lots of green left.

Aspen Colors, Kaibab National Forest

Autumn continues its slow but gradual progression up on the Kaibab Plateau on the northern Arizona Strip. Warm, shortening days along with cool nights still free of frost or an early snow are doing the job. Those conditions tell the aspen trees that there is no hurry to drop leaves. A gradual lessening of the green chlorophyll in their leaves reveals the other colors, especially yellow and gold, sometimes orange and red.

I was slowly cruising through the Kaibab National Forest between Jacob Lake and the North Rim of Grand Canyon, looking for the earliest colors. In the morning light I was able to get close to some lower branches with outstanding colors. The Still green foliage of the other trees behind it served as a rich background to contrast with, along with the clear blue sky.

Autumn gold, blue skies, warm sunlight, chilly nights. The best time of year.
