In a Native American legend, spirit hunters in the sky slew the Great Bear (a constellation) in autumn. The bear’s blood, dripping on the forests, changed many leaves to red.
Ah yes, my favorite time of year again. There’s nothing like seeing the forest come alive with color. But if these changes aren’t due to mythical bears in the sky, then what causes this amazing phenomenon?
Aspens, just like many other trees, take advantage of the suns rays for nourishment. Chlorophyll, found in leaves, helps with the photosynthesis process (making food from carbon dioxide and water). But it also has a major impact on the vibrant colors that we enjoy each autumn. As the days shorten and less light falls on the forest, trees automatically begin to slow their growth. Instead of collecting all their energy from the sun’s rays, they have to use food reserves that have collected in their leaves over the warm summer months. The green chlorophyll is slowly used up within the leaves, and what is left is vibrant yellow, red, or orange. What’s interesting is that these colors are always present in leaves, but we only see them when the more dominant green disappears.
