...unless you have something like paper birch in you woodpile, in which case you don't have to look very hard.
i don't burn a lot of wood at home, so i'm blast if i remember what i had delivered fifteen years ago (yeah, i split a half cord with my next door neighbors and i can probably go two more years before i need more, unless we have a bad winter with a lot of power outages) so i went ahead an took a look at my woodpile.
i guess i could just guess, but i like to give these little projects due diligence.
so i found this handy website and i actually brought in some of my firewood to take a close look at the grain with a jeweler's loupe, just because.
here's my woodpile. on close inspection, it is mostly american beech (fagus grandifolia), which i have learned has too high a water content to be burned when first cut, but makes fine firewood when it is dried a season or two.
i have a few logs of white ash (fraxinus americana), and one or two pieces of white birch (betula papyrifera) besides. i also happen to know there are a few pieces of apple wood that i brought home for carving and may have been checked or otherwise poor carving and are now firewood. that's sort of a win, because apple burns with a sweet smell, and i probably won't burn it at home, but take it to camp for cooking.
