The first two were published in Japan, and you can be excused for not
having seen these. The last was not. I think the problem died down,
because everyone was pretty much convinced by what happened at Spirit Lake
that the case was closed on YNP. If Fritz subsequently changed his mind (I
suspect that he has not), it is news to me.

Arct presented his stuff at GSA and at other meetings, but the data in his
thesis have never been published formally. Nevertheless, these data remain
the most compelling evidence for the allochthonous origin of the trees.
His thesis is referenced in the Chadwick and Yamamoto paper.
