Fall colors the Blue Ridge Mountains in North Carolina.
The name “Blue Ridge” was appointed to them by early American pioneers due to the blue hue they reflected against the horizon, it was later discovered the blue coloring was caused by a chemical compound released naturally by pine trees that causes a hazy condition that makes the Blue Ridge Mountains appear blue from a distance.
Fall Colors Accentuating a Blue Haze

Beautiful picture. But don’t all mountains appear blue from a distance? I thought its got to do with the shorter wavelength of blue light.
Thanks. Yes, to a certain extent this is true. I believe, the abundance of pine trees in this area compounds the effect.
Beautiful.
Thanks Pat!
