Research Team Says Extraterrestrial Impact To Blame For Ice Age Extinctions (More)

The book posted above pertains to a similar model (yes, I’ve finished it Blam, believe me, you *do* want it); those authors look at various current large lakes (including Lake Michigan) and other large bodies of water (Hudson’s Bay) for earlier supporting research on where the impacts happened. There’s quite a bit about the Carolina Bays, offshore Carolina Bays, and similar (basically identical) formations throughout the US and Canada, and used their orientations to find the impact points. Before they did that, they’d found for evidence for extraterrestrial origin of the parent impacts (the bays being ejecta craters), and the “black mat” which caps the Clovis period. Interestingly enough, the black mat appears to correspond to a similar, algal growth phenomenon which left fossil traces after the Permian-Triassic and Cretaceous-Tertiary events.

:’) None of the known *uniformitarian* models can do it, but those are eroding away. ;’)

Maybe Howard A. Boardman had it right...

Hole filler.......

Look at Hudson’s Bay and the entry drag of James Bay. The low angle impact gouged James Bay on the way in and holed out as Hudson’s Bay.

Thanks for all the pings.... This one ...I was thinking in biblical terms until I got to the thread. :)

have you (or anyone) seen research into possible location or area of any underwater crater from the presumed 540AD event? The muddy rain mentioned in some sources implies a water burst/impact, but presumably it is quite small given the effect, I don’t know if it would even leave a crater.

[LiteKeeper]

My research says they all drowned! And during a rather short span of time. They weren’t built real well for treading water.

The Lost Americans
by Frank C. Hibben

“In many places the Alaskan muck blanket is packed with animal bones and debris in trainload lots.”

“Within this mass, frozen solid. lie the twisted parts of animals and trees intermingled with lenses of ice and layers of peat and mosses. It looks as though in the middle of some catacystimic catastrophe. . . the whole Alaskan world of living animals and plants was suddenly frozen in mid- motion in a grim charade” (Frank C. Hibben, The Lost Americans, New York; Apollo Editions, 1961. pp. 90, 91).

“Tendons, ligaments, fragments skin and hair, hooves - all are preserved in the muck. In some cases, portions of animal flesh have been preserved. Bones of mammoths, mastodons, bison, horses, wolves, bears and lions are hopelessly entangled! One author counts 1,766 jaws and 4,838 meta- podials from ONE species of bison in a small area near Fairbanks, Alaska, alone. Archaeologist Hibben saw with his own eyes - and smelled with his own nostrils - the specter of death. North of Fairbanks, Alaska, he saw bulldozers pushing the melting muck into sluice boxes for the extraction of gold. As the dozers’ blades scooped up the melting gunk, mammoth tusks and bones “rolled up like shavings before a giant plane.” The stench of rotting flesh -tons of it - could be smelled for miles around.

Hibben and his colleagues walked the pits for days. As they followed the bulldozers they discovered perfect bison skulls with horns attached, mammoth skin with long black hair and jumbled masses of bones.

Appalling Death in Alaska

“Mammals there were in abundance, dumped in all attitudes of death. Most of them were pulled apart by some unexplained prehistoric catastrophic disturbance. Legs and torsos and heads and fragments were found together in piles or scattered separately” ((ibid., p.97). Logs, twisted trees, branches and stumps were interlaced with the mammal menagerie. The signs of sudden death were legion.

For example, in the Alaskan muck, stomachs of frozen mammoths have been discovered. These frozen stomach masses contain the leaves and grasses the animals had just eaten before death struck. Seemingly, no animal was spared.

“The young lie with the old, foal with dam and calf with cow. Whole herds of animals were apparently killed together, overcome by some common power” (ibid, p. 170).

Sudden and Unnatural Death

The muck pits of Alaska are filled with evidence of universal and catastrophic death. These animals simply did not perish by any ordinary means. Multiple thousands of animals in their prime were obliterated.

“We have gained from the muck pits of the Yukon Valley a picture of QUICK EXTINCTION.

Thanks. Santasaurus? ;’)

[ForGod'sSake]

Any new gems in the book that might be of interest? When do you anticipate doing your review??? I gather it's worth owning?

If you give a complete enough review maybe I won't have to buy it ;^)

[SunkenCiv]

;’) Buy it. The authors do a very good job explaining and relating everything; they’ve also concentrated on the Clovis event, but suggest further lines of their own research because of the evidence for the various waves of material from the supernova (the Clovis event was just the most recent).

[ForGod'sSake]

Buy it.< P> Well, OK.

Anyway, an item of curiousity for me is the apparent nastiness visited around Alaska at about the same time(I suspect other places will be discovered). Now, it seems catastrophic events are fairly rare and it would be quite the coincidence if our little planet were to experience two in a relatively short period of time. That is, a supernova's blast reaching us at roughly the same time as an impact from a comet/whatever. A single event is more likely -- whatever it was.

The evidence of gamma ray bombardment I gather is not in dispute? I don't know if it's been pointed out but I found THIS PIECE whilst looking for alternative sources for gamma rays:

BATSE requirements for a colliding comet source of gamma-ray bursts

R. Stephen White

Institute of Geophysics and Planetary Physics, University of California, Riverside, California 92521

The BATSE and Venera results place tight restrictions on possible sources of Gamma Ray Bursts, GRB. Collisions of magnetized comets in the solar system appear to satisfy the conditions of the observed isotropic direction distribution and the measured N(P_max) vs P_max distributions where X is fluence, flux, maximum flux or ratio of count rate at maximum to the threshold count rate. The distances to the bursts (GRB comet cloud), and density of comets is tailored to the observed data. To satisfy observations of N(P_max) vs P_max for the maximum gamma ray fluxes, P_max10^–5 erg cm^–2 s^–1 (about 30 bursts yr^–1), the comet density, n, should increase as n~a¹ from about 40 to 100 AU where a is the comet heliocentric distance. The turnover above 100 AU requires n~a^–1/2 to 200 AU to fit the Venera results and n~a^1/4 to 400 AU to fit the BATSE data. the masses of comets are from: 40–100 AU, about 9 earth masses, m_E; 100–200 AU about 25 m_E; and 100–400 AU, about 900 m_E. The spherical GRB comet cloud is neither the Oort Cloud nor the Kuiper Belt. Current minimum distances to bursts determined from time of arrival of the interplanetary network in combination with Watch on Ulyssus or Comptel or EGRET on CGRO neither verify nor prohibit this burst source. The gamma ray burst flux of 10^–5 erg cm^–2 s^–1 corresponds to a luminosity at 100 AU of 3±10²⁶ erg s^–1. Two colliding Halley's comets at a distance of 100 AU have a combined kinetic energy of 3±10²⁸ erg, a factor of about 100 greater than required by the bursts. Betatron acceleration in the compressed magnetic fields between the colliding comets could accelerate electrons to energies sufficient to produce the observed high energy gamma rays by Bremsstrahlung. Many of the observed features of gamma ray bursts can be explained by the solar comet collision source. ©1994 American Institute of Physics.

...which discusses comet collisions as a viable source. Impacting our atmosphere might work the same way???

I suppose the question is, if the P/H extinctions were caused by a single event, which is most likely?

Gotta run and see about actually getting some work done ;^)

I wholeheartedly agree. The comet was also debris from the explosion, either directly or indirectly; either the comet made the whole trip, or was pushed by the actual debris into the inner Solar System.
