Are companies still pulling up sunken timber from Lake Superior et al.?

I own several presentation pens made from ‘significant wood’, ie timber that was more important for its history than its role a termite food - one was a railway sleeper for the first railway line blah blah, and another from a tree that grew etc etc zzzzz. Both were presented for talks I gave, and twice someone went to considerable effort to create an attractive object with deeply embedded meaning and style.

I have never written a word with either of them, because I have other pens, biros, ballpoints, markers. They are (perhaps) too nice to be just thrown out. They will probably go to the grave with me. In centuries to come my future archaeological peers will scratch their heads and marvel at these largely uniform objects of enticingly practical use, but which never show signs of wear. They find quite a few of them, but never give a clue as to their use.

One will say ‘It reminds me of another mysterious object puzzle which they never solved…’
