What's the biggest oak tree you've ever seen? how about the biggest oak tree you've ever put into your wood stack? this weekend grandpa took me to a tree he said I could have, it would be good firewood, he tells me. I figured i'd entertain him, because he lives over an hour and a half away, I don't really want to transport wood that far. We drive the gator back into the waterway and he points down into a creek bottom, and there is a giant oak tree laying down with roots pulled out. He told me it was the biggest oak tree he's ever seen. i can't argue with him, but I'm only 32 and he's 81 with some experience in the timber. there were (I think) three main branches and the one that was near our side of the creek was so big I couldn't quite get my arms around it (that means almost 7 foot circumference) so it was a couple feet diameter. The main trunk was through some brush and it was early and cold and wet, so i didn't go down to it, but it was huge. I can't even guess how tall the thing was because the canopy fell into the brush and I just could see the top, I don't know how big oaks get, but it seemed to be well over 75 feet, maybe just shy of 100 to the very tallest branches. The nice thing about how it fell is that there is very little of the stuff laying on the ground, so it should be able to wait for me to get the time and resources to take care of it. If nothing else I just really want to get through that trunk to count the rings. i mean, something that big has to be over a couple hundred years old, right? I'll have to get pictures when i'm back home next time. I've been trying to convince my dad to get into wood burning, maybe if he has three years worth of oak all cut and split by his house he might be more willing to try it.
