there to locate any evidence of a meteorite and went on to examine other aspects of

What do we have so far? We have an event that seems to have affected Eastern
Siberia and Northern North America more severely than other places, though
whatever it was certainly amounted to a global event. We have already talked
about the evidence of “nuclear bombardment” in the Great Lakes region provided
by Firestone and Topping that tells us:
Radiocarbon dates for Pleistocene remains in northeastern North America are as
much as 10,000 years younger than for those in the western part of the country.[…]
Materials from the Gainey Paleoindian site in Michigan, radiocarbon dated at 2880
yr BC, are given an age by TL dating of 12,400 BC. It seems that there are so many
anomalies reported in the upper US and in Canada of this type, that they cannot be
explained by ancient aberrations in the atmosphere or other radiocarbon reservoirs,
nor by contamination of data samples. […]
Our research indicates that the entire Great Lakes region (and beyond) was
subjected to particle bombardment and a catastrophic nuclear irradiation that
produced secondary thermal neutrons from cosmic ray interactions. The neutrons
produced unusually large quantities of Pu239 and substantially altered the natural
uranium abundance ratios […]
Sharp increases in C14 are apparent in the marine data at 4,000, 32,000-34,000, and
12,500 BC. These increases are coincident with geomagnetic excursions. […]
The enormous energy released by the catastrophe at 12,500 BC could have heated
the atmosphere to over 1000 C over Michigan, and the neutron flux at more
northern locations would have melted considerable glacial ice. Radiation effects on
plants and animals exposed to the cosmic rays would have been lethal, comparable
to being irradiated in a 5 megawatt reactor more than 100 seconds.
The overall pattern of the catastrophe matches the pattern of mass extinction before
Holocene times. The Western Hemisphere was more affected than the Eastern,
North America more than South America, and eastern North America more than
western North America. Extinction in the Great lakes area was more rapid and
pronounced than elsewhere. Larger animals were more affected than smaller ones, a
pattern that conforms to the expectation that radiation exposure affects large bodies
more than smaller ones. 128
Firestone and Topping propose that this evidence of nuclear radiation is a result
of “cosmic ray bombardment” from, perhaps, a supernova. D.S. Allan, a biologist
at Cambridge, and J. B. Delair, coauthor of Cataclysm!, published in 1995 in the
U.K, also like the supernova hypothesis. Evidence of a supernova explosion, in the
