Slender white trunks reaching skyward and leaves fluttering even in the gentlest breeze—aspen trees are a symbol of the American wilderness. Found across the western states, especially in Utah and Colorado, these trees are the most widespread native species in North America. Their autumn foliage is breathtaking, with their leaves turning a vibrant yellow that lights up the landscape, as seen in today"s photo, which was taken near Marble, Colorado. Aspens are not only beautiful but also biologically fascinating. They grow in large colonies that originate from a single root system, making them some of the largest living organisms on Earth.
