Boone is most famous for his exploration and settlement of what is now Kentucky, which was then part of Virginia but on the other side of the mountains from the settled areas. As a young adult Boone supplemented his farm income by hunting and trapping game, and selling their pelts in the fur market.
Boone remains an iconic figure in American history. He was a legend in his own lifetime, especially after an account of his adventures was published in 1784 by John Filson, making him famous across Europe as the typical all-American frontiersman. An American edition made him equally famous across the United States.
