An Interactive Map That Predicts the Best Time to See Fall Foliage in 2017 Across the United States just released their interactive fall foliage map for 2017 that helps predict the best time for seeing the beautiful colors of autumn trees throughout the United States. It allows users to change the details of the map by week, via a slider at the bottom, to see when the foliage in their area is expected be at its peak for viewing. A great way to plan a drive through the hills.

The Science Of It All:

It all starts with photosynthesis. Leaves typically produce their vivid hues of green from spring through summer into early fall through the constant creation of Chlorophyll.

Many millions of these Chlorophyll cells saturate the leaves, ultimately making them appear green to the eye.

The Changing Colors:

Chlorophyll is not the only player in the fall leaf color game. Present in other leaves and trees are the compounds known as Carotenoids and Anthocyanins. As the Fall days begin to get shorter and shorter, the production of Chlorophyll slows to a hault, eventually giving way to the ‘true’ color of the leaf. (read more)
