Aspen - 2167

Colorado 2012; Each autumn, the shortening of the hours of daylight and the return of near freezing weather triggers the breakdown of chlorophyll, the chemical that gives plants their green color. As the green fades, the quaking aspen forests decorate their mountainous landscapes with spectacular displays of shades of yellow with occasional splashes of orange and red.
