New evidence supporting extraterrestrial impact at the start of the Younger Dryas

Looks to me like, a body passed close, moving south east from the polar regions. gravity caused the earth to shift and the rotation pole to move north. The resultant close pass caused a massive plasma discharge, region of grand canyon, with subsequent smaller bolts in Mexico.
The Earths change of rotational pole caused massive tsunamis that deposited up to 2,000 feet of muck and swept all in its path. The gauging of grand Canyon ejecta was deposited over a vast area with the bulk falling in Texas. The shifts caused Niagara falls to open up.
As the body moved south it caused uplift of the Alto Plano and tilting before returning to deep space.
Way out, I know but the evidence found supports it. Siberia, 15 degrees further south would have had the plants and animals found in the muck, mammoths and wooly rhinoceros. etc. The subsequent formation in the Andes of glaciers, which we now find have tropical plants under them as they retreat. The massive winds generated blew vast clouds of iron ore dust over the Bahamas and the vacuum left behind the passage, froze solid the dead animal remains.
The job of scientists is to collate all the data and test the theory, not denigrate it.

Thank you Dennis but that is not science. We have the data, how did it form.

Important question: How would a temp graph covering an cosmic impact
look like?
(1) The comet hits and immediately for the same month/year, you would
get a clear VERTICAL temp drop line…..
(2) after having reached the temp bottom, temps would recover again with
a inclined growing recovery temp line…..
This would be the graphical IMPACT PATTERN line……first vertical, then
inclined recovery….
With (1) and (2) we can search paleotemp. patterns which fit to impacts……..
Anyone, who proposes other variants than the impact variant, must prove that
the (1)+(2) impact pattern can/is also produced by other processes….
for example: Take the ocean reversal stream variant: This must produce a
vertical temp drop line within the SAME year, as a one-time impact would…..
……. The (see Wikipedia ) Dansgaard-Oeschger events are steady cyclic events
and NOT impacts, since both up and down- graph oscillations are inclined and
not do not contain the characteristic vertical impact line…..

“MMM. Clovis layer, formation of Niagara Falls, million of dead and frozen mammoths, piles of rubble in Texas, iron ore deposits in the Bahamas and many such similar.”

Contrary to your uneducated opinion, the actual mechanism for the formation of Niagara falls after the Ice sheets melted at the end of the last ice age is no mystery. You might Google up some actual geologic research on the subject before you try to pretend that it is. Or that no actual science has ever been done there. We see the very same kind of flood topography in the Pacific Northwest in the Glacial flood damaged terrains of the Channeled scablands of eastern Washington. What’s more, in Washington, the flow of water down those ancient channels has long since dried up. So we can study the resulting terrains there in great detail.
If you’re going to mention “piles of rubble” in Texas you’re going to have to be more specific. Such as giving specific GPSs. And a geologic map of the location that’s got your imagination in such a tizzy, and such a hook in your lip. This is after all the 21st century. Have you ever heard of a thing called Google Earth, or geologic maps? Believe it or not this entire continent has been imaged to a resolution of less than .5 meter per pixel. And that excellent image data is freely available to the public. The image data is all there for all the world to see if you know what you’re looking at. So if you are going to make such a fuss about those places, now would be a good time to begin learning to read a geologic map. And to how to study and interpret terrains in high resolution satellite imagery. But in fact, there’s a lot of places that fit that description on the outskirts of every major city. They’re called “Junk Yards”.
Your mention of “iron ore deposits in the Bahamas” also implies a mystery that may or may not exist. But again, the lack of specific locational data, or geologic maps of the place you are referring to makes it impossible to have any idea what you’re talking about. Much less form an opinion and speak about it.
As for the millions of dead, and frozen Mammoths, your use of the word “millions” is a silly and ridiculous over exaggeration. But from Wikipedia:

Preserved frozen remains of woolly mammoths, with much soft tissue remaining, have been found in the northern parts of Siberia. This is a rare occurrence, essentially requiring the animal to have been buried rapidly in liquid or semi-solids such as silt, mud and icy water, which then froze. This may have occurred in a number of ways. Mammoths may have been trapped in bogs or quicksands and either died of starvation or exposure, or drowning if they sank under the surface. The evidence of undigested food in the stomach and seed pods still in the mouth of many of the specimens suggests neither starvation nor exposure are likely. The maturity of this ingested vegetation places the time period in autumn rather than in spring when flowers would be expected. The animals may have fallen through ice into small ponds or potholes, entombing them. Many are certainly known to have been killed in rivers, perhaps through being swept away by river floods. In one location, by the Berelekh River in Yakutia in Siberia, more than 8,000 bones from at least 140 individual mammoths have been found in a single spot, apparently having been swept there by the current.[

Yes, the question as to the cause of the Mega faunal extinctions is part of the puzzle of what happened at the start of the Younger Dryas. But the 12,900 year old  “Clovis Layer” while being clear, and inescapable evidence of a major impact related, catastrophic climate change at the Pleistocene Holocene transition is not supportive evidence of Velikovsky’s silly, and delusional “Worlds In Collision” scenario.
It’s pretty obvious the you’re a Velikovskian Fundamentalist. I wouldn’t want to denigrate anyone’s religion. And it’s probably pointless to argue with a delusional framework. But regarding Velikovsky:

“The fact is that the whole of the ramshackle edifice of nonsense to be found scattered throughout the Velikovskian corpus is purported to have a historical…foundation, but that it has none.” ~John David North
“The philosopher David Hume urged that one should always hold it more likely that one had been deceived than that the laws of nature should stand suspended.” ~Frank Close

Whatever Velikovsky’s delusional take on reality was, it had nothing whatsoever to do with science, or the scientific method.
Velikovsky was no scientist. And he had no clue of things like physics, or orbital mechanics. He was also no astronomer; not by any stretch of the imagination. He didn’t even have any academic credentials to speak of. But according to him all of the laws of physics, and nature went right out the window 3,500 and 2,700 years ago when he says Venus, and Mars abruptly changed their courses and nearly collided with the Earth. He came to that stupid, and delusional conclusion by assuming that myth could inform science, and even supersede it.
From An Antidote to Velikovskian Delusions   

The events in Worlds in Collision are disproved by the complete absence of relevant physical evidence on Earth (such as characteristic debris in the world’s ice caps deposited during and after Earth’s near collisions with Venus and Mars 3,500 and 2,700 years ago, respectively; Ellenberger, 1984 [& Mewhinney, 1998]). If the debris Venus deposited in Earth’s atmosphere was so massive it caused 40 years of darkness after the Exodus, where is it today? There is no sign of it in the world’s ice caps or on the ocean bottoms.

All the physical evidence in Earth in Upheaval for the recent events in Worlds in Collision can be explained without errant planets in terms of climate change with ensuing habitat degradation, some of which was arguably a consequence of cosmic accretion events, i.e., massive fireball storms, associated with Clube & Napier’s model  for “coherent catastrophism” (Asher, 1994).

Then again, the topic of this post isn’t Velikovsky’s myth induced delusions is it? But honest to PhD Science. In fact the topic of this post is the new data presented in Evidence from central Mexico supporting the Younger Dryas extraterrestrial impact hypothesis. And since the astronomical model given in that real scientific paper is in fact Clube & Napier’s model for “coherent catastrophism” why not read the actual science in the paper they cited instead of trying to hijack this thread with your Velikovskian delusions?

Steve, I agree. Dennis and E.P. have seen fit to move their bar brawl from the Tusk to WUWT this week — and pick fights with patrons of the new shop! I am so embarrassed that WUWT has caught my blog’s disease. Their on-line behavior in forums is demonstrably hurtful to the subjects they advocate. What a shame, because they both have a lot to contribute if they would just sit-down, shut-up, and act with some dignity moving forward. I fear that will never happen.

Great Site! I have some comments regarding the complete disservice by scientists on both sides of the debate in neglecting all the other important features surrounding the Younger Dryas

Thank you Dennis
I am not uneducated and as a result, i find fault with a lot of Science mainly because of your type of response. Difficult questions raise silence or ad hominems or vitriol rather than rational debate.
Yes , I have questions and doubts but I ask them , investigate them, seek supporting data and try to learn. That is what science is about.
One estimate is that 5 million mammoths alone virtually make up the entire structure of several arctic islands. Something caused that and something massive, outside our experience.

Talking of absence of debris, where is all the stuff from Grand Canyon?

Ed Grondine speaks of oral traditions of the Assiniboine that give an account of an impact event that’s associated with the draining of one of the Glacial Lakes in the Pacific Northwest. There three glacial lakes at the foot of the Cordilleran Ice sheet. And only two can be suspects in those tribal memories.  Lake Columbia, and Lake Missoula.
I don’t know anything about Assiniboine oral traditions. But I do happen to know a fair amount about the Glacial Lakes of the Pacific Northwest. I lived in Spokane Washington for 16 years and am well familiar with the ‘Channeled Scablands’, Otherwise known as the Grand Coulee, of Eastern Washington. I used to spend my weekends flying an ultra light aircraft, and chasing coyotes down in those coulees, pretending I was Luke Skywalker chasing Womprats. It’s an old playground of mine. So I am very familiar with those catastrophic terrains. I am also familiar with the mechanism that caused the sudden drainage of lake Missoula.
During the ice age Glacial Lake Missoula was impounded behind an "Ice Dam" when a tongue of the Cordilleran Ice Sheet called the Purcell lobe extended down south far enough that it formed and ice damn that blocked the south fork of the Clark Fork River in Northern Idaho. Lake Missoula filled and drained many times during the ice age in a repeating cycle. The Glacier would advance, blocking the river and backing up the waters of Lake Missoula. When the lake level would get high enough that the ice damn couldn’t hold back the pressure of all that water the damn would fail, releasing a catastrophic flood downstream. The glacier would advance again, blocking the river again, and the cycle would repeat. Judging by the number of strand lines from Lake Missoula’s ancient beaches, the cycle may have repeated as many as 40 times during the last ice age. The last time it happened has been dated to about 10,000 years ago.

We should note here that since this new iteration of the YD impact hypothesis specifically ties the hypothesis to the Taurids. And the progressive breakup over thousands of years of the Taurid progenitor object. So in other words, the severe impact storms of the Pleistocene Holocene transition caused by Taurids may have been an annual event for millennia both before, and after 12,900 YA. And it just may be that the YD trigger event was only the worst of them.
The last great flood from Lake Missoula has been dated about 10,000 YA. So the Assiniboine memories may be related to that last event. And well after the YD trigger event.

Another blockage occurred to the west where the Okanogan Lobe of the CIS plugged the Columbia River’s course creating Glacial Lake Columbia; a body of water with a 500 square mile surface area at maximum fill. The same process happened there many times during the ice age as well.
And the biggest of all of the mega floods of the late Pleistocene can also ruled out as being associated with the Younger Dryas event because it dates to too long ago. The Bonneville flood released nearly 1,000 cubic miles of water. And the volume was twice as large as the biggest Missoula Flood. However, unlike the Missoula Floods, the Bonneville Flood occurred over a period of several weeks approximately 17,400 years ago.
The geology of the region has been intensely studied. And the mechanism of the repeated formation, and subsequent ice damn failures of the Glacial Lakes of the Pacific Northwest is well understood. Although the story of how geologists came to understand how it all actually did happen is a very exiting read in itself, so far there has been nothing found in the geological record to indicate any of the often repeated great floods of the Channeled Scablands of Eastern Washington were related to an impact event.
Mr Grondine tells us:

“The “Great Fire” was seen by other peoples besides the Sioux (I can not share who with you now, nor their accounts), but you have to remember that the Sioux proper were farther north, most likely along the open Cordillera.”

The  problem with that statement is that any memories of a time when there was water in either Glacial Lakes Missoula, or Columbia must also be memories of a time when anyplace north of either of them was under the Cordilleran Ice Sheet. And Lake Bonneville is off the suspect list of lakes the first peoples may have remembered because at 17,400 YA it was too long ago.
The use of the term “open Cordillera” is a bit confusing.
All of the Mountain ranges of the western half of the continent extending from Southern Mexico to Alaska, from the Rockies of Wyoming, Colorado, Utah and Montana to the Sierra Nevada, Cascade, and Olympic Ranges of the Western Coastal states, as well as all of the mountain ranges of Western Canada can be described by the broad term “Open Cordillera”. So it’s not clear which Mountains Mr Grondine is referring to with his use of that term. But the Bitterroot Range formed southwestern shores of Lake Missoula. And every thing north of the lake was under the Cordilleran Ice Sheet untill about 10,000 years ago. All of the Canadian Rockies are sometimes called the Canadian Cordillera. But they were under the CIS during the ice age too. And the mountains west of the Channeled scablands and south of the CIS were the Cascades
There couldn’t have been any human settlements north of Glacial Lake Missoula at the time. Because the Cordilleran Ice sheet that blanketed the western half of the northern tier of the continent was every bit as thick and extensive as the Laurentide Ice Sheet that blanketed the Northeastern side of the continent. It was up to two miles thick in places. And it blanketed almost all of western Canada all the way to the Pacific
The CIS extended as far south as the northern shores of glacial Lakes Missoula, and Columbia. The Purcell Trench lobe of the CIS was the lobe that extended still further south to block the Clark Fork River in Northern Idaho with an ice damn impounding the waters of Lake Missoula. And an ice dam formed by the Okanogan lobe of the CIS blocked the Columbia River Channel and impounded the waters of Lake Columbia
An ice damn was required for a glacial lake to fill up. And that only happened during an ice age. So at any time in the past when there was water in Lake Missoula or lake Columbia there was also an extensive ice sheet that made anywhere north of either of them unfit for human habitation.
Simply put: No ice sheet=no ice dam. No ice dam=no glacial lake. Or: Glacial lake=ice dam=ice sheet north of lake=unfit for human habitation.
Unfortunately, even if those oral traditions are accounts of an impact event that’s associated with the draining of one of the Glacial Lakes, the catastrophic damage done to the terrains of the Pacific Northwest by the the great floods was so extensive, and so extreme, that it may have removed all traces of anything but the floods themselves.

I am wondering if the Cayman Trench topography could indicate a ‘blow out’ of enormous proportions? Since the impact trajectory was from NNW going SSE leaving those Carolina impact craters, the Cayman area would seem to be the ‘front’ of the material receiving the shock wave.
Or perhaps it is antipodal to the actual impact site? It just boggles my mind that such an evident catastrophic site is not speculated upon with determination.
