The 2023 Fall Foliage Map helps plan trips to witness the changing colors of leaves during autumn. The Great Smoky Mountains draw thousands of visitors each year. Chlorophyll gives leaves their green color during spring and summer. Carotenoids and Anthocyanins contribute to the colors of leaves in autumn. Trees drop their leaves to prevent damage and death during winter. Fallen leaves create rich soil, which provides nutrients and water to trees and plants in spring. https://smokymountains.com/fall-foliage-map/
