Native People have many legends of giants, all around the world. One of the legends of the Cherokee involves a giant they called "Judaculla" who was described as a "slant-eyed giant" who ruled the mountains long ago.
The Natives said that this decorated rock in the area of Sylva, North Carolina, marked the giant's territory and even had his 7-fingered print from when he set his hand upon the rock to steady himself. The drawings are believed to be 2000 to 3000 years old.
No one has deciphered the writing on the rock and, in fact, there are supposedly other rocks in the area with such drawings, some ruined with time and others still probably hidden by overgrowth.
What makes the story even more interesting is that the area reports a great deal of what are considered classic "portal" events (think "Skinwalker Ranch"). These types of things include UFOs sightings, spook lights, and ghostly goings on.
