Hi
It looks a bit narrow for a railroad, as well. My
guess: some company exec didn't want to hear about
any problems...but gravity doesn't care about your
rank.
Until I got to the text describing this, I was
thinking it was some sort of natural feature,
maybe from ancient volcanic activity. There IS
such a feature in Lake Superior Provincial park in
Ontario, on the way down to the pictographs. I was
all set to be enlightened by Capt. Paul or Dr.
Nat.

It may have been intended for a narrow-gauge
railway, similar to those used to bring RR cars into
the backwoods for lumbering. I don't know whether
narrow gauge lines were used in iron mining; they
were in coal mining.
