1. Cumberland Gap – The Cumberland Gap is a narrow pass through the long ridge of the Cumberland Mountains, within the Appalachian Mountains, near the junction of the U. S. states of Kentucky, Virginia, and Tennessee. Long used by Native Americans, the Cumberland Gap was brought to the attention of settlers in 1750 by Thomas Walker, a Virginia physician and explorer. The path was explored by a team of frontiersmen led by Daniel Boone, making it accessible to pioneers who used it to journey into the frontiers of Kentucky. The Cumberland Gap is one of many passes in the Appalachian Mountains and it lies within Cumberland Gap National Historical Park and is located on the border of present-day Kentucky and Virginia, approximately 0.25 miles northeast of the tri-state marker with Tennessee. Scientists have dated this region to the Cambrian or Pennsylvanian period, the unique landscape seen today is a result of the uplift of sedimentary rock in conjunction with several million years of weathering and erosion. These features include narrow ridges, steep cliffs, overlooks, the Cumberland Gap is now known as a wind gap since water no longer flows through it. The V-shaped gap serves as a gateway to the west, the base of the gap is about 300 feet above the valley floor below even though the north side of the pass was lowered 20 feet during the construction of Old U. S. Route 25E. To the south the ridge rises 600 feet above the pass, because it is centrally located in the United States, the region around Cumberland Gap experiences all four seasons. The summers are sunny, warm and humid with average temperatures in the mid to upper 90s F. In the winter months, January through March, temperatures range in the 30s to 40s F and are mild with rain. The nearest cities are Middlesboro, Kentucky, and Harrogate, Tennessee, the gap was formed by the development of three major structural features, the Pine Mountain Thrust Sheet, the Middlesboro Syncline, and the Rocky Face Fault. Lateral compressive forces of sedimentary rocks from deep layers of the Earths crust pushing upward 320 to 200 million years ago created the thrust sheet, resistance on the fault from the opposing Cumberland Mountain to Pine Mountain caused the U-shaped structure of the Middlesboro Syncline. The once flat-lying sedimentary rocks were now deformed roughly 40 degrees northwest, further constriction to the northwest of Cumberland Mountain developed into a fault trending north-to-south called the Rocky Face Fault, which eventually cut through Cumberland Mountain. This combination of geological processes created ideal conditions for weathering. However, the discovery of the Middlesboro impact structure has proposed new details in the formation of Cumberland Gap, less than 300 million years ago a meteorite, approximately the size of a football field, struck the earth, creating the Middlesboro Crater. One of three astroblemes in the state, it is a 3. 7-mile diameter meteorite impact crater with the city of Middlesboro, Kentucky, detailed mapping by geologists in the 1960s led many to interpret the geological features of the area to be a site of an ancient impact. In 1966 Robert Dietz discovered shatter cones in sandstone, proving recent speculation. Shatter cones, a rock-shattering pattern naturally formed only during events, are found in abundance in the areaCumberland Gap – Cumberland Gap in winter
2. Pine Mountain (Appalachian Mountains) – Pine Mountain is a ridge in the Appalachian Mountains running through Kentucky, Virginia and Tennessee. It extends about 125 miles from near Jellico, Tennessee, to a location near Elkhorn City, birch Knob, the highest point, is 3,273 feet above sea level and is located on the Kentucky-Virginia border. It has been a barrier to transportation as the Cumberland River at Pineville, the other is Hickory Creek near Jellico, TN. Wildlife is abundant on Pine Mountain, the land is claimed to be the Black Bear Capital of Kentucky. Black bears, elk, rattlesnakes, and deer are found on Pine Mountain, Pine Mountain Settlement School William Creech, Sr. Pound GapPine Mountain (Appalachian Mountains) – US 23 in Kentucky with Pine Mountain in the background
3. Tri-State Peak – Tri-State Peak is a mountain located in the Cumberland Gap National Historical Park, near the saddle of the gap. It gets its name from being on the tri-point of the states of Kentucky, Tennessee, the elevation at the tri-state marker is 1,990 feet. The marker can be accessed via the tri-state peak trail, and is about 1.2 miles from the visitors center. The site also includes a marker denoting the location as being on the Royal Colonial Boundary of 1665, which was marked by the American Society of Civil EngineersTri-State Peak – Tri-State Peak marker
