When I was a very young man logging old growth redwood in NorCal we were using a D8 on the far side of the drainage as the tail hold for our tower.
Which on one lift we managed to drag off the road and about 100 yards into the creek below. Ended up on its side. Scary as fuck for us choker setters…
Fucked up the dozer pretty good. Took us three days to retrieve, untangle the mainline and rerig. At least we didn’t lose much oil or hydraulic fluid…
