Why are the Blue Ridge Mountains blue? The trees growing along the ridgelines produce high levels of a compound call isoprene. The isoprene hovers around the thickly forested mountains like a haze and scatters the different wavelengths of light and the short, small waves of #blue dominate our receptors. Of course, the best place to see the effect is while resting or traveling along the Blue Ridge Parkway in #NorthCarolina and #Virginia. With amazing views, hiking trails, waterfalls and wildlife, the #mountains might be blue, but you won't feel that way. Photo @blueridgenps courtesy of Joshua T.
