I have always been skeptical when it came to "Indian Marker Trees". The ones I looked at in the Texas coastal areas over the years had probably been bent over by storms and in most cases weren't old enough for Indian association. I found it strange that there was no mention in the newspaper article of the species of the subject tree nor an estimate of its age. The tree in the photos appears to be a species of Ash, Fraxinus sp. Ash trees do live for as long as 250 years. Its fun idea that there might be surviving "Indian Marker Trees". Realistically it would be quite impossible to prove from a scientific perspective any Indian association several hundred years ago with a particular tree.
Interesting article..
I lean towards Reds' evaluation,,,a bent tree even a few hundred yrs old would be redundant..They had proper
road signs going up by that time
