MOOSE, Wyo. — Crisp mornings, cool evenings, and changing leaves are sure signs of Fall in the Tetons.


According to Grand Teton National Park (GTNP), Quaking Aspens most commonly change to shades of yellow in the fall. Depending on the season, aspens can retain their color for several weeks. Stand health plays a role in whether the trees display strong colors and retain leaves later into the fall.
