You might have heard of Alpinglow s an optical phenomenon in which a horizontal red glowing band is observed on the horizon opposite to the sun, typically on a mountain. Well, we want to know if you have experienced Arborglow, a similar phenomenon but with trees instead of mountains. It is that moment after the sun sets and you look up into the canopy and still see a muted light as the sun sets below the horizon. There is also the pre arborglow moment when the sun sets and the tree is back lit by the sun, this is particular special when in the forest and the sun light diffracts though the trees. Share your experience or photos with these phenomena and if you have not experienced or heard of it before, remember you heard it first on American Grove. The best photo or comment posted before May 15th, 2014 to capture this phenomena will receive an American Grove mug, hat, and/or shirt ! Post in a comment below.
