I have hunted this line extensively over the years so wasn't expecting to find much of anything. I took my trusty 3 tine pitchfork along just in case I was attacked by coyotes or beavers. None of those materialized, so I had to be content with probing likely spots. About 15 feet from a pole site(and after about 2 hrs of hiking) I got my first hit! A nice unmarked M-2140.
