I'd say the trees on My sister's Property were middle aged, around 40 or so. The big trees on my property I do not know. I have cedars up to 100 years old, and tamarack growing up amongst them. They actually have quite a different appearance due to growing in the dense cedar. Much taller then on the cabin property. If we have a dry spring or summer this year, I may be able to get some down and out, then I'll know the age.
