Cumberland Gap (el. 1,600 ft or 490 m) is a pass through the Cumberland Mountains region of the Appalachian Mountains, also known as the Cumberland Water Gap, at the junction of the U.S. states of Tennessee, Kentucky, and Virginia. Famous in American history for its role as a key passageway through the lower central Appalachians, it was an important part of the Wilderness Road and is now part of the Cumberland Gap National Historical Park. Long used by Native Americans, the Cumberland Gap was brought to the attention of settlers in 1750 by Dr. Thomas Walker, a Virginia physician and explorer. The path was widened by a team of loggers led by Daniel Boone, making it accessible to pioneers who used it to journey into the western frontiers of Kentucky and Tennessee.
The passage created by Cumberland Gap was well-traveled by Native Americans long before the arrival of European-American settlers. The earliest written account of Cumberland Gap dates to the 1670s and was written by Abraham Wood of Virginia.
The gap was named for Prince William, Duke of Cumberland, who had many places named for him in the American colonies after the Battle of Culloden. The explorer Thomas Walker gave the name to the Cumberland River in 1750, and the name soon spread to many other features in the region, such as the Cumberland Gap. In 1769 Joseph Martin built a fort nearby at present-day Rose Hill, Virginia, on behalf of Dr. Walker's land claimants. But Martin and his men were chased out of the area by Native Americans, and Martin himself did not return until 1775.
In 1775 Daniel Boone, hired by the Transylvania Company, arrived in the region leading a company of men to widen the path through the gap to make settlement of Kentucky and Tennessee easier. On his arrival Boone discovered that Martin had beaten him to Powell Valley, where Martin and his men were clearing land for their own settlement – the westernmost settlement in English colonial America at the time. By the 1790s the trail that Boone and his men built was widened to accommodate wagon traffic and sometimes became known as the Wilderness Road.
Several American Civil War engagements were centered in and around the Cumberland Gap and are sometimes called Battle of the Cumberland Gap. In June 1862, Union Army General George W. Morgan captured the gap for the Union. In September of that year, Confederate States Army forces under Edmund Kirby Smith occupied the Gap during General Braxton Bragg's Kentucky Invasion. The following year, in a bloodless engagement in September 1863, Union Army troops under General Ambrose Burnside forced the surrender of 2,300 Confederates defending the gap, gaining Union control of the gap for the remainder of the war.
It is estimated that between 200,000 and 300,000 migrants passed through the gap on their way into Kentucky and the Ohio Valley before 1810. Today 18,000 cars pass beneath the site daily, and 1,200,000 people visit the park on the site annually.
The 12-mile (19 km) long Cumberland Gap consists of four geologic features: the Yellow Creek valley, the natural gap in the Cumberland Mountain ridge, the eroded gap in Pine Mountain, and Middlesboro crater.
Middlesboro crater is a 3-mile (4.8 km) diameter meteorite impact crater in which Middlesboro, Kentucky, is located. The crater was identified in 1966 when Robert Dietz discovered shatter cones in sandstone, which led to the further identification of shocked quartz. Shatter cones, a rock shattering pattern naturally formed only during impact events, are found in abundance in the area. In September 2003 the site was designated a Distinguished Geologic Site by the Kentucky Society of Professional Geologists.
Without Middlesboro crater, it would have been difficult for packhorses to navigate this gap and improbable that wagon roads would have been constructed at an early date. Middlesboro is the only place in the world where coal is mined inside an impact crater. Special mining techniques must be used in the complicated strata of this crater. (Milam & Kuehn, 36).
The gap was formed by an ancient creek, flowing southward, which cut through the land being pushed up to form the mountains. As the land rose even more, the creek reversed direction flowing into the Cumberland River to the north.
