This seems to have played itself out 14 years ago. I had read this
exchange in _Geology_, but it took a while to find the references...
I did find them on a talk.origins FAQ, though:
<http://www.talkorigins.org/faqs/polystrate/yellowstone.html>

Fritz, W.J., 1980. Reinterpretation of the depositional environment of the
Yellowstone "fossil forests". Geology, v.8, p.309-313.

Yuretich, R.F., 1984. Yellowstone fossil forests: New evidence for burial
in place. Geology, v.12, p.159-162.

Fritz, W.J., 1984. Comment and Reply on "Yellowstone fossil forests: New
evidence for burial in place." Geology, v.12, p.638-639.

Yuretich, R.F., 1984. Comment and Reply on "Yellowstone fossil forests: New
evidence for burial in place." Geology, v.12, p.639.

=====

In the last exchange, both Fritz and Yuretich agree that the trees at
Specimen Ridge were buried in situ, both from root evidence and from
the surrounding sedimentation. They both agree that there are other
fossil forests where the evidence is much more touchy or favors
transport interpretations. (Or some combination of both.)

I'm not sure what 'uniformitarianism' has to do with either model, but
that seems to be the end of the story (no further publications on the
matter).
