The platforms installed every 10 feet were presumably fir saplings? approximately 12-16 ft long and say 4-6 inches in diameter. Were they cut on the island, and if so where are the tree stumps?

Thems bigger than saplings. Thems posts.The platforms installed every 10 feet were presumably fir saplings? approximately 12-16 ft long and say 4-6 inches in diameter. Were they cut on the island, and if so where are the tree stumps?
Nahh.You are probably correct but there is one more thing to consider.
When a Christmas tree is harvested, the stump can start growing again. THEORETICALLY it might be possible to find a tree with a different amount of tree rings in the stump vs the growth on top.
Your reliance on the internet is flawed. tree growth is dependent on environment. In my area. A white oak tree measured 8” in 1868 might be 10” now. Other areas conifers might grow 1” in diameter per year! You have to core trees located in the environment to determine age.Okay I'm an idiot. Took this long to correct a math error.
The Internet says tree ring growth is .1 to .2
Inches diameter per year.
So using the average of .15, 200 years growth is 30 inches diameter, much different than 15 to 20 feet I said. Even a 400 year old tree would be only 5 feet diameter.
Also the foliage under the pictured trees doesn't look like spruce, and I happen to know a forest fire went through the area
about 50 years ago. It might make a difference in how trees regenerate?
Thanks for the info. I was trying to get to the point of looking at a spruce tree and knowing by circumference how old it is.Your reliance on the internet is flawed. tree growth is dependent on environment. In my area.

Dendrochronology.Thanks for the info. I was trying to get to the point of looking at a spruce tree and knowing by circumference how old it is.
So core an old spruce on the island, get growth rate, and start coring spruces high and low (then plugging them). If you could find a tree with a different number of tree rings high and low, THEORETICALLY you know when the log platforms were cut and installed in the pit (post #6).
Simple, what?
Horse/mule wound sized devices.Never heard of such a thing. I’m interested if anyone used such a contraption out west. I’m doubtful because the trees were so large.
