[Rockhounds] More Comments by Graham Hancock About Younger Dryas Impact Hypothesis

[Tim Fisher]

Seems he's at it again. While I do respect the need for keeping an open mind about prevailing hypotheses in geology and paleontology, when the evidence stacks up against an controversial/tentative hypothesis then you at some point are forced to admit that it may be off. No evidence = keep trying or accept the inevitable. The Younger Dryas has been explored to death since the sensational asteroid/comet/large meteorite impact hypothesis. It has since been put nicely to bed where it needs to stay.

Subject: [Rockhounds] More Comments by Graham Hancock About Younger Dryas Impact Hypothesis

Popular writer and fringe archaeologist Graham

Hancock has written a new and extended commentary

about the Younger Dryas Impact Hypothesis. He is quite

unhappy about what he believes how he and other

proponents of this hypothesis have been treated by so-called

“gradualists” whoever they are, within the scientific

community.The commentary is at:

Contrary to what Mr. Hancock seems to believe,

neocatastrophism has become popular among

geologists and scientists as discussed in:

Marriner, N., Morhange, C. and Skrimshire, S., 2010.

Geoscience meets the four horsemen?: Tracking the

rise of neocatastrophism. Global and Planetary

Change, 74(1), pp.43-48.

https://www.researchgate.net/publication/222537265_Geoscience_meets_the_four_horsemen_Tracking_the_rise_of_neocatastrophism

One item that Jason Calavito did not mention in his

commentaries, is that Mr. Hancock does not appreciate

the significance of recent research about the chronology

of the Missoula (Spokane) Floods and older “Ancient

Cataclysmic Floods.” The identification of numerous

Missoula Floods has nothing to do with any imaginary

conspiracy by an equally imaginary cabal of nameless

“gradualists.” Rather the recognition is based upon

multiple, unconformity-bounded sets of flood deposits.

These flood deposits are separated subaerial exposure

surfaces in which paleosols, including some very

well-developed calcretes, and terrestrial animals

burrows have developed. There also are separate sets

of clastic dikes truncated at different unconformities.

Some of different sets offlood deposits have been

dated using, where possible, by either radiocarbon dating

magnetostratigraphy, optically stimulated luminescence

dating, or tephrachronology. The oldest of these

deposits predate 1.77 million years ago. There exists

an abundance of published evidence that demonstrates

the occurrence of innumerable Missoula-like

megafloods over a period greater than 1.77 million

years.

Also, Mr. Hancock overlooks Antonio Zamora ‘s

badly flawed optically stimulated luminescence

arguments that ignores the context of these dates

and collaborating pollen records from the fills of

the Carolina Bays.

Finally, Mr. Hancock is seemingly unaware of the lack of

any credible evidence supporting the existence of Michael

Davias’ seemingly imaginary Saginaw Bay impact

structure that is used to explain the Carolina Bays. The

geology that region is well known enough to show that

there is a complete lack of the deformation of bedrock

and overlying Quaternary deposits that such an impact

would have caused. Also, any geophysical signature of

such as impact structure is lacking. Finally, regional

sedimentary and paleoenvironmental archives for that

time period lack and are undisturbed by the ejecta

deposits that such an impact would have created. The

Saginaw Bay impact structure is just one of a few likely

imaginary Pleistocene impact craters that have been

reported in the Great lakes region.

Yours,

Paul H.
