where does the smoky mountains begin and end
Great Smoky Mountains The Great Smoky Mountains stretch from the Pigeon River in the northeast to the Little Tennessee River to the southwest. The northwestern half of the range gives way to a series of elongate ridges known as the "Foothills," the outermost of which include Chilhowee Mountain and English Mountain. The range is roughly bounded on the south by the Tuckasegee River and to the southeast by Soco Creek and Jonathan Creek. The Great Smokies comprise parts of Blount County, Sevier County, and Cocke County in Tennessee and Swain County and Haywood County in North Carolina.
Appalachian Mountains The Appalachian Mountains[a] (French: les Appalaches), often called the Appalachians, are a system of mountains in eastern North America. The Appalachians first formed roughly 480 million years ago during the Ordovician Period. They once reached elevations similar to those of the Alps and the Rocky Mountains before experiencing natural erosion.[4][5] The Appalachian chain is a barrier to east-west travel, as it forms a series of alternating ridgelines and valleys oriented in opposition to most highways and railroads running east-west.
