Given that Frank Hibben's descriptions of his Alaskan
muck along with his interpretations of the Alaskan muck
and a major Alaskan Paleo-Indian Site have been
demonstrated by various Cultural Resource Management
reports and dozens of published peer-reviewed papers to
be a mixture of science fiction and fantasy, there is
nothing for anyone to apologize about.

Also, I have just looked at the paper, which is:

Murton, J. B., M. D. Bateman, S. R. Dallimore, J. T. Teller
and Z. Yang, 2010, Identification of Younger Dryas outburst
flood path from Lake Agassiz to the Arctic Ocean. Nature.
vol. 464, no. 7289, pp. 740-743 doi:10.1038/nature08954
http://www.nature.com/nature/journal/v464/n7289/abs/nature08954.html

There is absolutely nothing in this paper that relates
to the Alaskan loess deposits, which Hibben called "muck".
In fact, there are innumerable OSL, radiocarbon dates, and
dated ash beds that clearly demonstrate that Hibben's
?muck? deposits predate the Younger Dryas event by tens
of thousands of years to over 3 million years. What is known
about the age of the Alaskan "muck" precludes them from
having any association with the draining of Lake Agassiz.

"or to Dr. Firestone."

Again, going through the above paper, it is clear there is
nothing in it that supports any of Firestone?s claims,
i.e. his imaginary Chippewa Basin impact crater. There are
the Charity Shoals in Lake Ontario and the Can-AM structure
in Lake Huron. However, neither of these features are likely
of the right age to be related to a Younger Dryas impact.
The Can-AM structure is likely at least 500 million years
old. There is nothing for anyone to apologize for.

?By the way, the "blueberries" on Mars are impact
vapor condensates, not water condensates.?

A lot of geologists and impact specialists disagree with you.

Best Wishes,
