Did you know what causes the leaves to change color? Light absorbing, green pigmented chlorophyll masks the other color-producing substances in a leaf during the summer. In the fall, when the trees stop producing chlorophyll, the making effect is eliminated and the yellows and reds that were hidden under the green chlorophyll become visible. Now you know the rest of the story and can share it with family and friends! Lt. St. Germain Lake is beautiful in the fall by boat or land. Take a walk or go on one of our wonderful biking trails in the northwoods and view the colors this fall.
