I think I estimate about 35 rings on this close up from one of the pictures!
So some of our younger members may not have been around when they were planted but many of us were. :~)
I am always interested in how changing our woods are every year, there's always new planting, current logging, mature stuff that will be next to go, and everything in between, and now, storm damage. Yes, we mourn when they're cut, but there will be another forest and the diversity of age and sunlight and shade makes it real interesting.
Hmm, nice photo of the tree rings. Fifty year rotation, well y'all get a bit more precip up there than we did on the Rim.
