The Great Smokey Mountains (or "Great Smokies" as they are often called) are a beautiful mountain range in Western North Carolina and Eastern Tennessee.
But why are they called that?
Well... you're in luck!
That has been written about extensively in this article by the Great Smokey Mountain National Park: How did the Great Smoky Mountains get their name?
Basically:
They are called that because of history dating back to the Cherokee Native Americans and appreciation for the "smoky" blue haze and abundant moisture / fog / cloud-cover.
