For The Washington Post, Lauren Tierney and Joe Fox mapped fall foliage colors across the United States:
Forested areas in the United States host a variety of tree species. The evergreens shed leaves gradually, as promised in their name. The leaves of deciduous varieties change from green to yellow, orange or red before letting go entirely. Using USDA forest species data, we mapped the thickets of fall colors you may encounter in the densely wooded parts of the country.
Nice. Be sure to click through to the full story to see leaf profiles and an animation of the changing colors as fall arrives.
