Spilling Thought: Quaking aspens provide beautiful scenery and a rich habitat for wildlife. Aspen, the most widely distributed tree in North America, are one of the few deciduous trees hearty enough to survive in a harsh environment of Rocky Mountain #NationalPark in #Colorado. One of the most striking characteristics of the aspen is the beautiful splashes of fall color it adds to the mountainsides. This magical color change starts in early September and can last into October. Photo of @rockynps courtesy of Jacob W. Frank (@jacobwfrank). Want to be featured on @USInterior’s account?
