The great Allegheny ranges, stretching from northeast to southwest, attain their highest altitude in western North Carolina. They come down southwestward out of Virginia in the Blue Ridge and other ranges, forming a high plateau, having the Blue Ridge on the eastern side, and on the western, forming the boundary between North Carolina and Tennessee, the chain known in various parts as the Stony, Iron, Great Smoky and Unaka Mountains, while beyond, to the northwest, the Cumberland Mountains extend in a parallel range through East Tennessee. There are also various cross-chains, among them the Black Mountains. In these ranges are eighty-two peaks that rise above five thousand feet and forty-three exceeding six thousand feet. The highest mountains of the Blue Ridge in North Carolina are the Grandfather and the Pinnacle, rising nearly six thousand feet. In the Great Smoky Mountains, Clingman's Dome is sixty-six hundred and sixty feet high and Mount Guyot sixty-six hundred and thirty-six feet. The highest peak of all is in the Black Mountains, and it is the highest east of the Rockies, Mount Mitchell rising sixty-six hundred and eighty-eight feet. Between and among these ranges are the sources of Tennessee River, in the Clinch River, the Holston and its North Fork, and the French Broad, their head streams coming westward out of Virginia and North Carolina through the mountain passes. The extensive mountain region they drain in North Carolina and East Tennessee is a most attractive district, noted as a health resort, and famous for the sturdy independence of its people, while along the Tennessee and upon the mountains near it were fought some of the greatest battles of the Civil War.
