The markings should be at the same height as when they were craved. Every see a tree that has barbwire nailed to it. In never gets higher as the tree grows. Thanks, marion
Plants achieve little growth through cell division - most growth comes from cell elongation. What does this mean? What was near the ground 100 years ago can be much higher depending on the type of tree. Happy hunting.
I sure wish you could get a clearer photograph and from a closer distance. More than likely they climbed from their horse upon those limbs and made the carving. I sure wish it was a clearer picture, I may be able to help you.
