The Cumberland Gap, named that way in honor of Prince William, Duke of Cumberland and son of King George II, was first mentioned in any accounts by British colonialists in 1670. This Gap is a geological structure placed within the Appalachian Mountains and connects the states of Kentucky, Tennessee and Virginia. It is also the most renown example of what is called a wind tunnel, given that this structure is one of the few that did not result from the erosion caused by water. The importance of this Gap is that it forms a continuous passageway between the Appalachian Mountains and connects with the west. At the time of the Native Americans, and before European settlers moved in and discovered this geological structure, the Indians used it as a passageway to be able to pass from east to west without having to cross the entire Appalachian Mountain range.
