The park contains ancient Native American burial grounds dating from the earliest inhabitants of this area, all the way up to the time of the Cherokee removal known as the "Trail of Tears". The Creek and Cherokee tribes at various times used the natural rock formations to trap and corral horses, as a natural fortress in times of war, and as a sheltered village area in times of peace. The site played host to the only peace treaty ever signed between the Creek and Cherokee tribes. During The American Civil War, the site was used as a hiding place for horses and their owners wishing to avoid invaders from the north and the Confederate recruiters and "bushwhackers".
