Estes Park is at an elevation of 7,522 feet. With the elevation and cooler temperatures, the aspen's leaves are changing colors. The vibrant gold color of the leaves stand out in the middle of the green forest.
Aspen trees are medium sized and are normally 20 to 80 feet tall. The bark is a smooth white color with thin, round leaves. In the wind or gentle breeze, the leaves shake like fluttering butterfly wings.
