Cumberland Gap, 500 m high mountain pass on the west side of the Appalachians in the USA on the border between Kentucky, Virginia and Tennessee. After the legendary pathfinder Daniel Boone cleared a road through the pass in 1775 by following an ancient Indian trail, the route, later known as the Wilderness Road, became of great importance for the early colonization of the Midwest. Approx. 300,000 settlers are believed to have used the strenuous route to cross the mountains. The pass and parts of Wilderness Road have been part of the 83 km2 large, beautiful Cumberland Gap National Historical Park since 1955.
