Like Eugene, I have real doubts about this being Tsali Rock. Obviously none of us will ever know for certain, but to me it just seems too small, by far, to have been utilized for a fairly extensive period of time. On the other hand, the cliffs Eugene mentions, and I'm certain they are the same ones I recall as being an area known for rattlesnakes, are the location I've always thought was Tsali Rock. It's all problematic, beyond anything approaching sound documentation, and quite interesting. Oddly enough, Sam Hunnicutt, who chased bears all through this area, never mentions it. Nor, I'm pretty sure, does John Parris. One would think that both of them would have been intrigued by the story.
After all, old Sam was through this area time and again (read his book Twenty Years Hunting and Fishing in the Smokies--just reprinted which means it can be had for $20 or so rather than the $1500 or thereabouts an original fetched), and John Parris wrote a little book on The Cherokee Story.
