that's a 600 pair cable. if it is live, there will be a guy in a tent there for quite a while putting that back together.
We were digging in new water main and had an abandoned 600 pair that we were digging through regularly, and a live line nearby.
We took a chunk of the dead line, all frayed out like that, and would toss it by the ditch to torment the boss or inspectors or anyone else who would fall for it.
This is the auger truck I last operated, I spotted it along the road a couple of weeks ago.
The auger is like a honey badger. Auger don't give a shit, if it does not stop it outright, it's toast.
