No apology needed by the way! I thought you had an excellent point, especially because that location was one where I said, "yep, that's it", hung the tape, and moved on. I didn't really look around it (risky).
I had to be in New Melle this afternoon, and on the way home couldn't resist detouring to Broemm. to check it out. I saw the squiggle to the NE where I think you were at. I thought the big ditch-like feature closest to the road looked odd and definitely not as mapped. It seemed like that spot had been re-graded (??) So it was sort of a confusing area map-wise.
