The color of this Quaking Aspen (Populus tremuloides) grove begins to shift from vibrant green to a brilliant yellow signaling the coming snows of winter.
Aspens have the widest range of any tree in North America spanning from the Alaskan interior all the way to Mexico! It's a wonder that they've spread so far as they typically "reproduce" via root sprouts or suckers. However, they are able to reproduce via seed, it's just that the viability window is short and the environmental requirements are narrow so most don't survive. This suckering or cloning behavior has created one of the largest living organisms on earth, the Pando clone in Utah. This single genetic grove is over 100 acres in size and weighs some 14 million pounds! It may not be getting larger anytime soon as a study from 2018 found that it hasn't grown in the past 30+ years.
I'm not done with the interesting facts though. You've probably heard of petroglyphs, maybe pictographs, but have you heard of arborglyphs? It's carving of shapes, symbols and words into living tree's and Aspens have an abundance of them throughout the Western US. Basque sheepherders, who came to the US in the mid-1800's, spent lonely summers amongst high country Aspen groves. With no one to keep them company they took to carving names, poems, thoughts and images into the trees. These arborglyphs are slowly disappearing with the death of each Aspen tree which rarely live more than 150 years.
