The Cumberland Gap, 60 miles north of Knoxville, is, like Ellis Island, an icon in the settling of America. It’s estimated that 200,000 to 300,000 people traveled thru the gap between 1775 and 1810, leaving the coastal states and putting down roots in what would become Kentucky and Tennessee. It was the only practical way through the Appalachians for 100 miles north or south. Indian attacks made the more expensive alternate way -- down the Ohio River -- risky.
