I really doubt it... I work with a bunch of forresters and we have discussed this many times. Most trees and oaks in particular are not old enough. Some can be though as we aged one at around 400 years old looking for the oldest Oak in Ga. Its base was the size of a VW. My point is this. I have a pic of a small oak in my yard in 1927. A very small tree. The oak blythe got it this last year and I had to cut it down, It had grown to be a monster in size since 1927. That being said the tree you are showing in my opinion could not be old enough to have been bent by the Indians. They also talk about eagles being carved and so forth. I am kinda skeptical on this. I carved a Giant smooth bark elm about 30 years ago with our names and you can still read them but the odds of it lasting say 200 years is slim but plausable I guess.
Also you bend a tree and it gets any size it will fracture in the bend for sure. I have read this stuff on sites before but I remain a skeptic, The tree you are showing in my opinion is around 40 years old and was damaged or trapped and bent over by another tree when young.
Hey I have been wrong before
