Ok, this is tougher than I thought. I almost forgot to POST a picture today...
This was one of the trees on a lumber truck at work:

I thought it was interesting because the snow reminded me of the layers of sediments on cliffs. When I just looked at the picture on my computer, I noticed all the cut marks on the tree itself. That means this one wasn't cut down by a huge logging machine. It was likely cut by one guy, with a chainsaw. You can tell where he had to re-position the saw to get through the tree. Weird I know, but I found it interesting.
