Hi Dave=0AAs a further check I got a piece of Yellow birch from my woodpile=
. The out 20 mm of wood took 22 years to grow,=0Anot much more than half th=
e estimated growth rate of the monster on McNutts - I have no idea where my=
 sample grew.=0AThe width of the rings will be inversely proportional to th=
e age. A young tree grows much bigger rings than an old tree for reasons to=
o involved to discuss here. An old tree for sure.=0APaul=0A=A0=0AOn Saturda=
