So, I guess, I made good guess. I am also guessing, being able to identify a hard or soft wood by grain is a valuable skill for a firewood hunter. The closer the rings, the harder the wood, the harder the wood the better it burns. Compare the rings to something you know, no need to know exactly what it is other than curiosity. Am I wrong?
Dave my guess is black birch,I've got quite a bit of it in log form,shown on an earlier forum of locust woods,I've heard it burns nicely.
I'm not sure, was in the load I had delivered. I think there might be more in the one pile I still have left, will get photos if I think of it.new pictures.Maybe the red ones are closely related to black birch ?
Never looked close at the leaves, will try to remember next summer to see if there is a difference.

I'd say that is a Paper Birch, same as all the other birches up there. There are, as far as I know, only two types of Birch in Alaska, and besides Paper Birch the other one is Dwarf Birch. Black Birch doesn't grow anywhere close to South Central Alaska.
I agree, it's all paper birch.
Interesting to me was the University of Fairbanks did a BTU calculation (in 1996) of it & it matches up with yellow birch BTU content.
23,600,000 BTUs/cord
But I don't believe they tested the red barked trees ? Might be 25 mil BTUs/cord.
I'm guessing they tested trees from the Fairbanks area, maybe 230 mile South, the BTU content is different.
I think the red or dark colored bark trees are "Mutants". Mutants with higher BTUs.
I'll go with it (red birch) having higher BTUs .
