Riding my bike on the lakefront almost every day, I get to enjoy the beautiful scenery with the skyline as a backdrop. Fall is especially neat as the colors start to change. I always get a kick out of the seasonal ‘leaf peepers’ who get in their cars and drive to the hinterlands to see the leaves change when we have a symphony of color in downtown Chicago.
But, what makes the leaves change color in the Fall? Science Made Simple says, “The bright reds and purples we see in leaves are made mostly in the fall. In some trees, like maples, glucose is trapped in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn cause the leaves turn this glucose into a red color. The brown color of trees like oaks is made from wastes left in the leaves.
“It is the combination of all these things that make the beautiful fall foliage colors we enjoy each year.
These photos are from this week the beginning of the Fall season. It is still early and there has not been a great deal of color change yet. The full dimension of Fall color won’t occur till later in the season.
Consider these the overture.
