How did Daniel Boone and his men widen the Cumberland Gap?

Daniel Boone and his men widened the Cumberland Gap by clearing a path through the dense forests and rugged terrain of the Appalachian Mountains. They used axes and other tools to remove trees, brush, and obstacles, making it easier for settlers to pass through the gap. This effort was part of Boone's broader mission to create a route for westward expansion, ultimately facilitating migration into Kentucky and beyond. Their work contributed significantly to the opening of the American frontier during the late 18th century.
