This fall we were at the cabin and I was watching the colors of the leaves turn. The difference was very noticeable from one day to the next. I had never really studied just how the green just fades away and leaves only the golden colors of the aspens. I started picking a few of them so that I could study them. It has been several months since I got them and found it was interesting that the colors stay stable until they turn fully gold and then they start to turn brown even after they are picked.
