Hi,
Oh, Please don't cut a beech tree down. There is really no need to do that for any reason. Besides, even though I take sometimes 30, 40, or 50 pictures or more depending on how many markings there are on a tree, I still have had to go back to a tree to check something on it many times. I went to an area one weekend they were doing construction on the little bridge on the dirt road where this tree was at. I did my best to document it. It was hard because there was so much new graffiti on it. The next weekend I went back and the area looked so different, it looked like a completely different spot. They had cleared the land right there because they were putting in a new bridge right next to the old one and they cut down that tree. It was probably about 3 or 4 foot in diameter. It was probably 300 to 400 years old. What a waste of history! I have wanted to go back to that tree but it is gone.
It is usually pretty easy to tell the new from the old markings. For one thing the old markings are a little wider as the bark has stretched as the tree grows. Also when you are looking at coded writing and symbols as opposed to someone just carving in their name, you'll see oddities such as letters with pointers, or one letter leaning for no apparent reason, just strange things that are really out of place if you think abou it. Look at some of the pictures I've posted here and you'll see some of the things I'm talking about. I once found a tree with a date of 1967 on it and I took pictures of it just to be able to go back and look at how the letters are still so much thinner and "newer" looking than the old carvings we find. Even though they are almost 40 years old, they have a much newer look still than the 100 plus year old carvings do.
Good luck,
