Questions people ask
Why does color come earlier in some places?
Higher ground turns first. In the Great Smoky Mountains, color can start as early as mid-September at the highest elevations, develops above 4,000 feet from early to mid-October, and reaches the lower and middle slopes between mid-October and early November.Source: National Park Service, Great Smoky Mountains fall color ↗ (opens in a new tab)
