What Wyoming tree has white bark and black knots with twittering leaves that deepen into yellow, gold and a rich red? Yes, it’s the beautiful Aspen. As the days shorten and chill, the trees retreat from feeding and filling their roots. Yellow and gold blazes the hills as the chlorophyll departs and the green falls away. Sugar finishes the dance in red until the snow comes and the Aspen drops it’s leaves.

Okay here’s a close up of the leaves in yellow, you can still see the green in the veins.
