Try reading a tree's life by the rings.... Here's what I see,,, wrong or right?
Johns 1st pic I count 15 to 16 yrs growth,,, tree's around it grew smaller (as the pic shows). Tallest tree & good water source = big rings.... Lots of sun along the feild or hedgerow a good life with good seasons!
gmans log is around 30 yrs. It also looks like it was a leaner or grew against another tree. It started getting crowded out later in life by other taller tree's for the last 8 yrs or so = Un-uniform rings on one side & thinner outer rings...... A fighter of a tree, good to grow another 30 yrs if it were not for a certain energetic bowyer...
I can't help but to see these things while looking at osage tree rings. Wonder which ring saw the biggest deer & will you take that bucks great, great grandchild with the backing of your bow seeing the whole show?
