- The Blue Ridge, part of the Appalachian range, was created by the uplifting of the Earth’s tectonic plates 1.1 billion to 250 million years ago. At over 1 billion years of age, the Blue Ridge Mountains are among the oldest in the world, second only to South Africa’s Barberton greenstone belt.

Humans arrived in the Blue Ridge perhaps as early as 12,000 years ago. The Siouxan Manhouacs, Iroquois, and Shawnee all hunted and fished the Blue Ridge in Virginia, and the Cherokee lived in the Blue Ridge in what is now Great Smoky Mountains National Park. The mountains played host to foxhunting on foot with hound dogs and night coon hunts.

Blue Ridge Mountains History. The Roanoke Valley in Virginia's Blue Ridge began to form when settlers began to ride into the frontier behind the Blue Ridge Mountains. These settlers established roots in the region by building homes and claiming farmland in the Roanoke Valley and neighboring Botetourt and Franklin counties in the mid 1700s.
Water did that. Millions of years of slow erosion carved the mountains and plateau that we know today. The Blue Ridge of southwestern Virginia marks the second largest drainage divide in North America. It is the divide between rivers that drain toward the Atlantic and those that drain to the Gulf of Mexico.
