The Cumberland Gap National Historical Park is located in the border between Kentucky, Tennessee, and Virginia. The Cumberland Gap is a narrow pass through the long ridge of the Cumberland Mountains that served as a key passageway for not only settlers, but Native Americans, and migratory species, such as the buffalo. A team of frontiersmen led by Daniel Boone explored the path, making it accessible to pioneers who used it to journey into the western frontiers of Kentucky and Tennessee. This selection by American author, artist, photographer, and naturalist Virginia Eifert, describes the importance of this region. I wrote it for the blog in Simplified Gregg.
