where did the blue ridge mountains get their name
Blue Ridge Mountains The Blue Ridge Mountains are noted for having a bluish color when seen from a distance. Trees put the "blue" in Blue Ridge, from the isoprene released into the atmosphere,[2] thereby contributing to the characteristic haze on the mountains and their distinctive color.[3]
Cumberland Gap Famous in American colonial history for its role as a key passageway through the lower central Appalachians, it was an important part of the Wilderness Road and is now part of the Cumberland Gap National Historical Park.
Great Smoky Mountains The name "Smoky" comes from the natural fog that often hangs over the range and presents as large smoke plumes from a distance. This fog is caused by the vegetation exhaling volatile organic compounds, chemicals that have a high vapor pressure and easily form vapors at normal temperature and pressure.[6]
