4 Why So Blue?

The Blue Ridge Mountains get their name from their iconic blue haze. The Cherokee were the first to coin the phrase, referring to the mountains as the Shaconage (shah-CON-ug-gee) or 'the land of the blue smoke. In recent years, scientists discovered that the trees found scattered across the Blue Ridge Mountains produce volatile hydrocarbons, one of which is isoprene. Isoprene is emitted by trees as a way to protect themselves from the stress of excess heat, especially on summer days. Once it is released, it can interact with other molecules, which scatter blue light from the sun, creating a distinctive blueish hazy effect over the mountains.

3 Origin Of The Blue Ridge Parkway

The idea to create the Blue Ridge Parkway was born when President Franklin Roosevelt visited Virginia's first Civilian Conservation Corps camp in 1933 as they built Shenandoah’s Skyline Drive. The then US Senator Harry Byrd suggested that the road should be extended to connect to the Great Smoky Mountains National Park, and Roosevelt was so impressed with the Skyline Drive that he approved the project.
