Does anyone have a GOOD example with a picture of the scale that was used to tell the age of a typical BG. I thought this would be straight forward but apparently NOT.
I'm looking at a half dozen scales from a 5" BG with a 15x loop and having great difficulty discerning the winter season rings. Is there something aout BG that make then difficult to read?
Thanks to anyone that can provide me with a good link with good photos on the issue.
