A couple of years ago we had about a 42 inch Doug Fir right next to the road hit, split it to the ground like that, blew bark and limbs off. No charring at the bottom, but it was on fire about 75 feet up. We could barely lob water into it with our brush truck. I called our DNR Fire contact, they got a faller out there. The homeowner didn't want us to fall it, he wanted his farmhand to do it. I wasn't comfortable with that, so he and I bumped chests and wasted breath for an hour until the faller got there, when the owner recognized him he said OK, you should have said it was such and such coming. I had told him, and proceeded to point that out. Tree tipped over just like we planned. When it got down, we started chasing the fire in it. The owner had wanted to cut it into logs for his mill. We started cutting it into pieces to get to the fire, there ended up not being a single good log in it, even the stump was split into 6 different blocks.
Amazing how much damage a simple steam explosion like that can do.
