Kinda cool, I have a oak tree by the end of my driveway it has a weird bend to it, like it grew 3 feet and the trunk was bent 90 degrees then grew 3 feet sideways then resumed growing straight. I have driven by that tree for 24 years and always thought it was just a weird growing tree. I saw a random article about native american marker trees and that is exactly what I have. There are burial mounds about 2 miles north of me so it was defiantly and area that was inhabited and used. Wonder what my marker tree marked, a good spot to hunt? I will take a picture when I get back home after I increment bore the tree to age it.
