Aspens in color, Bighorn Mountains, near North Tongue River, Wyoming

Going out west early into mid September is not a guarantee for having leaves with great fall colors. We knew that, but going up higher in altitude can always be a game changer. The highest peak in the Bighorn Mountains is over 4,000 meters and this photo location near our campsite at North Tongue Campground in Bighorn National Forest was still at an altitude of 2,400 m. Higher elevation triggers earlier frost and so it was no surprise to see some aspens in their beautiful fall colors.
