Located in the extreme northeastern corner of the state, Johnson County lies on the western slope of the Appalachian Mountains. It is bounded by Virginia on the north and North Carolina on the south and east. Hilly and mountainous, the county covers approximately 290 square miles, and the highest elevation is Snake Mountain at 5,574 feet. The most fertile and flat land can be found along the Little Doe River and Roan and Beaverdam Creeks.
Before the arrival of white settlers, the Cherokees, Creeks, and Yuchis used the area as a hunting and burial ground. Evidence of prehistoric mound builders has been found. The first white settlers were mostly English, but also included some Scots-Irish and Germans. The first settlement occurred at the confluence of a buffalo trail and three wilderness trails. The settlement name, Trade, attests to its importance as a meeting place where settlers, frontiersmen, and Native Americans swapped goods and stories.
Daniel Boone hunted and explored the area between 1761 and 1769. Numerous settlers followed Boone's trail through the wilderness, including John Honeycutt, who built a cabin on Roan Creek. Honeycutt entertained several well-known frontiersmen, including Boone and James Robertson, who achieved fame in the Watauga and Cumberland settlements. Before the end of the century, additional settlements had been established at Little Doe, Shady Valley, and Laurel Bloomery.
