I am not sure how it happened, we were about halfway through the trail just after the deep holes and before the bridge when I heard something and stopped. I was just little surprised when I got out and saw that. It was wedged so tight we couldn't budge it. Got the sawing running, made one cut, and then could not get it running again. Tried multiple hi lifts and bottle jack position combos, finally rocked the truck in reverse slightly with it lifted an got the log to roll some. It was a bitch for at least an hour.
