That point may be placed between say about 45,000 BCE and 8,249 BCE.? Contrary to what Mr. Grondine claims above, none of the projectile points reported by Hibben (1943) has been dated as being older 11,000 BP. For example, the ?Yuma? points, which are now called Eden points, are securely dated as having been made between 8,800 to 9,400 BP as discussed in detail by Holliday (2000). There is not a single shred of credible evidence that any of the so-called ?Yuma? points found? by Hibben (1943) could be as old as 45,000 BP as is incorrectly claimed above. In addition, there are much younger prehistoric projectile points, which are found in Alaska, that superficially resemble Eden (Yuma) points. It is quite possible that Dr. Hibben in his zeal to find PaleoIndian artifacts misidentified these points as ?Yuma? points. This possibility is demonstrated by the fact that Hibben (1943) reported a ?Yuma? Paleo-Indian point from sediments, which are exposed along the coastal cliffs of Chinitna Bay, southern Alaska and now are know to be Late Holocene in age as discussed in detail by Thorson et al. (1978, 1980). The fact that Thorson et al. (1978, 1980) obtained a date of 300+/-130 years from the stratum, in which Hibben (1943) found one of his Alaskan ?Yuma? points certainly indicates how unreliable Mr. Grondine?s estimate of 8,249 to 45,000 BP for Hibben?s points happens to be as it is wrong by at least 8,000 years in this case. Similarly, as documented in detail by Thorson et al. (1978, 1980), Hibben (1943) reported ?mammoth bones? eroding out of the same Late Holocene deposits on the beaches of Chinitna Bay, southern Alaska, where the only large bones to be found come from beached whales. The Folsom points, which Hibben (1943) reported from these deposits, are part of the Folsom Complex, which is well dated at 10,900-10,200 B.P. as discussed by Holliday (2000). Thus, it is well documented in the published, peer-reviewed literature that either Folsom or ?Yuma? points dates to 45,000 BP as Mr. Grondine falsely claims above. Reference Cited: Holliday, V.

The statement not completely true. It is true that Dr. Frank W. Hibben was one of the early archaeologists involved in the study of Paleo-Indian sites. However, he had very little to do with any of the early significant research concerning the Folsom and Clovis complexes. His main contribution to Paleo-Indian research was his research at the Sandia Cave Site, which is still hopelessly mired in controversy and his Sandia Complex, which has been discredited as a valid cultural complex. An article about Hibben, Sandia Cave, and his Paleo-Indian research is "News: History, Santa Fe / NM, Columns Trail dust, 09/16/2006 - Sandia Cave significance mired in controversy" at; http://www.freenewmexican.com/news/49330.html The article concludes: ?But scholars generally have moved away from acceptance of Sandia Man as a genuine landmark in our prehistory. And today, one seldom finds reference to him in professional handbooks and texts.? Mr. Grondine continued: ?and in 1933 and 1941 he traveled to Alaska trying to find remains of early man along the "Siberian Land Bridge". Hibben's account of the work of the pioneering archaeologists makes for a fine read, and his description of what he found in Alaska, and where he found it, makes for particularly fascinating reading....? ...lengthy quote from Hibben?s publications deleted... It is curious how catastrophists selectively quote only those parts of Hibben?s published papers, which support the specific catastrophe of their choice being argued for. For example, they never quote Hibben (1943), where he stated: ?The deposits known as muck may be definitely described, in the opinion of the writer, as loess material. All characteristics seem to indicate a wind-borne origin from comparatively local sources, as the material resembles local bedrock. The outwash plains of the local glaciations are likely points of origin for this material. These mucks deposits are from four to one hundred feet thick and are especially well known in the vicinity of Fairbanks, Circle , and other gold mining centers of the Upper Yukon and the Tanana where the muck overlies auriferous gravels. Muck deposits of considerable thickness, however, are found in the lower reaches of the Yukon, on the Koyukuk River, on the Kuskokwim and on several places along the Arctic coast, and " This quote and other material from Hibben (1943), which catastrophist conveniently do not inform their readers about: 1. shows that the deposits containing mangled and twisted vegetation remains are only a very, very small part of the deposits, which Hibben called "muck". Hibben (1943) clearly states that the vast majority of his "muck" deposits most likely consist of wind-blown loess and related colluvial and solifluction deposits. 2. The deposits, which called "muck" are the same Pliocene and Quaternary age deposits, which Dr. Westgate, Dr. Pewe, Dr. Muhs, and many other geologists studied and published on in great detail in the 60 years since Hibben (1943) was published. A selection of these references can be found at the end of this post. In addition Hibben (1943) stated: "Twisted and torn trees are piled in splintered masses concentrated in what must be regarded as ephemeral canyons or arroyo cuts." In the thread "Re: New www page on mammoths" on the Talk.origins newsgroup, Dr. Andrew MacRae, an experienced Canadian geologist stated about these and similar deposits, which comprise Hibben's evidence for catastrophic deposition. " Wow. Debris flows. Slumps initiated by permafrost melt. Crevasse fills in permafrost. The question is not whether or not this is evidence of a "catastrophe", it is why on Earth authors who cite this material interpret non-stratified, poorly-stratified, "jumbled" deposits with disarticulated skeletons as evidence of a global catastrophe? It is a stretch, to say the least. It is far from the only mechanism which could produce a deposit with these features. There are many modern processes, which can produce equivalent deposits "jumbled together in no discernable order", and many of these processes occur in Alaska and other arctic areas today (including Siberia). How do you propose eliminating these other processes as a possibility in order that a "catastrophe" of regional or global scope becomes the only viable hypothesis? Many authors which cite this material as evidence do not even bother mentioning the alternatives." The fact of the matter is that deposits, which are identical to those, which he interprets to be the result of an impact-generated mega-tsunami, can be seen today within the Arctic permafrost regions as the result of various permafrost and thermokarst processes. Having conducted most of his PaleoIndian research in the hot and dry Southwestern United States, these are processes, with which Hibben likely was completely unfamiliar. Mr. Grondine continued: "Clearly Hibben's description of the area where he made his point find and the location studied by the later archaeologists you mention do not match." In this case, Mr. Grondine is completely wrong as documented by Thorson et al. (1978, 1980). Thorson et al. (1978, 1980) were able to precisely locate the exact stratum in which the Hibben allegedly found the Yuma point on the shore of Chinitna Bay, southern Alaska. They were able to precisely relocated the exact location of finds using photographs, which Hibben had taken, and detailed directions, which Hibben had provided them in personal correspondence for their research. In addition, Hibben's own photographs showed that there had been an insignificant modification of the coast by coastal erosion. Finally, as documented in Thorson et al. (1978, 1980), they were able to match layer for layer the stratigraphy observed by Hibben with the stratigraphy, which they observed. Thorson et al. (1978, 1980) clearly demolishes the claim by Mr. Grondine that the location, at which Hibben found his ?Yuma Point? at Chinitna Bay and the area and the area studied by later archaeologists are different areas.

Quaternary Research. vol. 13, no. 2, pp. 259-273. doi:10.1016/0033-5894(80)90033-2 Mr. Grondine continued: "But then perhaps the point of their exercise was simply to smear Hibbens and catastrophism?" LOL, LOL, LOL. Catastrophists are paranoid group of people. :-) :-) The fact of the matter is that Hibben's ideas are so lacking in any substance and so discredited by later research that conventional archaeologists and geologists by that time were totally indifferent to his ideas. This paranoid feeling that conventional scientists are out to suppressed and smear them is one reason that certain catastrophists are regarded as amusing cranks If Mr. Grondine would read Thorson et al. (1978, 1980), he would find that the reason that they relocated the site, which Hibbens (1943) reported on Chinitia Bay, was to relocate and test what according to this paper were extensive and potentially significant early archeologic sites. They though that this site provided a possibly opportunity to test the Bering Landbridge hypothesis. However, instead of Pleistcoene mammoth?s bones, they found recent whale bones. Also, they found that the layer, which yielded Hibben claimed to have yielded a Paleo-Indian "Yuma" point, was only 170 to 430 years old according to a radiocarbon date from piece of wood collected from that layer. This layer, Hibben's so- called "habitation level" did not even contain any artifacts even though it exposed for long distance along the shore of Chinitia Bay. By the way, Thorson et al. (1978, 1980) makes no mention of the catastrophist ideas of Hibben (1943). Like many geologists and arcaheologists of their time, they were likely completely indifferent to his catastrophist ideas. Thorson et al. (1978, 1980) investigated Hibben (1943) because they accepted what had wrote about finding a significant a Paleo-Indian Site along the shore of Chinitia Bay.

Provide me with one and I'll consider your arguments. If Mr. Grondine would read, Preston (1995), he would find that I am not the person, who is arguing that Hibben committed fraud. Rather, the allegations of fraud were raised by paleontologists, geologists, and archaeologists, who directly with worked Hibben. The numerous irregularities and contradictions in Hibben's published research, which they interpreted to be evidence of fraud, from what I can see, could just as easily be explained sloppiness, poor management, and gross incompetence on Hibben's part. I pointed out Preston (1995) because, in order to fully evaluate Hibben (1943), people need to know that he is a very controversial figure in American archaeology and not as well regarded by conventional archaeologists as Mr. Grondine incorrectly portrays him to be. References Cited: Preston, Douglas, 1995, The mystery of Sandia Cave. The New Yorker. vol. 71, pp. 66-72 (June 12, 1995) In reference to the "muck" deposits within the Fairbanks area, Mr. Grondine wrote: "You've intentionally (sic) mistated my point, Paul. The only deposit of interest here is the Holocene start deposit, with find." No, I have not misstated your point. Your distinction between Holocene and pre-Holocene "muck" within the Fairbanks area is a scientifically bankrupt distinction. In the Fairbanks area, the Holocene "muck" is virtually identical in composition, layering, and stratigraphy to the pre-Holocene "muck". They differ mainly in that the Holocene "muck" completely lacks the mummified megafauna and any of the major beds of twisted and mangled wood, which Hibben (1943) regarded as being created by repeated volcanic catastrophes. Except for these two differences, the parts of the Engineering and Fairbanks loesses and Ready Bullion Formation, which contain archaeological deposits, are virtually identical in texture, sedimentary structures, pedogenic (soil) structures, cyrogenic structures, stratigraphic layering, composition and other physical characteristics to the underlying and older parts of these formations, which lack archaeological deposits. This is demonstrated by the numerous papers, to which I provide citations to in my first post at: http://six.pairlist.net/pipermail/meteorite-list/2007-June/035570.html In addition, I am not misstating your point because both you and Hibben (1943) are mistaken in assigning a Holocene age to beds, which numerous studies clearly have demonstrated to range in age from Late Pleistocene to Pliocene in age. The mummified remains of extinct mammals and vast majority of beds of mangled and twisted wood, which Hibben (1943) regarded to be evidence of major catastrophes occur in loess and related deposits, which are Late Pleistocene in age as demonstrated by the numerous papers by Pewe, Muhs, Westgate, and others, which are listed at the end of this post. Hibben (1943) mistakenly regarded all of these "muck" deposits to contain archaeological material. He failed to understand the considerable extent that younger Holocene "muck" deposits and the artifacts, which they contained, had been churned into older deposits by mining operations, slumping from the sides, and material being washed down the sides downing hydraulic mining. Inevitably, the jumbled mass of reworked material, including artifacts, froze in the Arctic climate into solid "muck", which Hibben carelessly confused with in place "muck". Mr. Geodine also wrote: EP - Well, Paul, so far you have not mentioned any researchers familiar with impact mega-tsunami, or who would know what to look for. Some used to claim that the dinosaurs were killed by food poisoning.- EP After I stated ?That you have to dismiss 60 years of ?post war research?, which I discussed in my post, out-of-hand as ?BS? just shows to me how completely lacking in either any evidence or arguments, outside of Hibben?s antiquated and discredited research, which you have to support your ideas about there being any tsunami deposits in the so-called ?Alaskan muck?.? It does not make a single shred of difference, whether experts in mega-tsunami have looked at the so-called Alaskan ?muck? deposits. All any geologist has to do is read the published detailed descriptions of these sediments and compare them with what has been published about mega-tsunami deposits in the scientific literature, i.e. Dawson and Shi (2000), Dawson and Stewart (2007), Kortekaas and Dawson (2007), and Scheffers Kelletat (2003, 2004), and many others to find that there is complete lack of any similarity between the so-called Alaskan ?muck? and known and hypothetical mega-tsunami deposits. Enough is known and has been published about the physical characteristics of mega-tsunami deposits that it is completely unnecessary for an expert in mega-tsunami deposits to have examined them. Any competent geologist, by researching what has been published in the scientific literature, would be quite capable of recognizing any mega-tsunami deposits present within the so-called Alaskan ?muck? deposits of Hibben (1943).

Mr. Geodine wrote: ?Paul - Why do I feel you're trying to obscure rather than enlighten? Because generally, people use more words when they're lying.? The fact of matter is that I am not obscuring anything. Discussion the origin of the Alaskan ?muck? and explaining why conventional scientists argue the way they do cannot be done in either short sound bites or by mindless repeating carefully selected quotes from Hibbens (1943) as he does. The fact he has to slander me, on the laughably silly excuse that I use too many words, as far as I am concerned is nothing more than a smokescreen on his part to hide the fact that he completely lacks any credible evidence or arguments, which support his scientifically bankrupt and theory about there being mega-tsunami deposits in the Alaskan ?musk?. Mr. Geodine wrote: ?Why not use just a few words to tell me the reason why Hibben's faked his research?? The fact of the matter is that contrary to what Mr. Geodine states above, I am not the one, who is claiming Hibben faked his research. As noted previously, it was geologists, archaeologists, and paleontologists, who worked closed with Hibben, who suspected him of fraud as discussed in detail by Preston (1995). Preston (1995) explains in great detail their reasons. If Mr. Grondine would take the time to read Preston (1995), he would find that archaeologists are divided on whether Hibben faked some of his research or he was just extremely careless and sloppy in his research techniques. The numerous contradictions, inconsistencies in his papers; the errors, in which he was caught by coworkers (such as sending out a bone from another site to be radiocarbon dated labeled as being from Sandia Cave); and so forth have been argued to be evidence of either case depending a person?s point of view. The controversy over fraud concerns his research at Sandia Cave and has absolutely nothing to do with his ideas about catastrophism as is well documented by Preston (1995). I was not surprised at all when Preston (1995) was published. When I was working at a certain Paleo-Indian site, I would listen when the archaeologists there would get into discussions about whether either Hibben or someone fabricated the Sandia Points and whether Hibbens faked parts of his research or not. In none of these discussions, did any consensus emerge as to what really happened. Basically, Preston (1995) realized that it is impossible for anyone to determine at this point in time whether Hibben has been either fairly or unfairly accused of committing fraud. It is a complex controversy, for which there appears to be no final answer. I tend to believe that extremely careless and sloppy research, record keeping, and sample labeling on Dr. Hibben?s part has been misinterpreted as fraud.

The New Yorker. vol. 71, pp. 66-72 (June 12, 1995) Mr. Geodine also wrote: ?I can think of many who will go to extreme efforts to avoid admitting to catastrophic impacts having occurred, and I can tell you why they do so... ? LOL, LOL, Oh well, this is nothing more the typical reaction of pseudoscience, in which completely imaginary conspiracy or conspiracy on the part of anonymous mainstream scientists is blamed for the failure of a pet theory to gain any sort of general acceptance In another post, Mr., Geodine wrote: ?Having reflected overnight on Paul's objections, a few more points are in order. The original deposits which (sic) Gibben observed were destroyed by the hydraulic mining operation which exposed them. How equivalent the deposits which Paul cited stuides of were to the ones (sic) Gibben's observed I can't say, but there is no resemblance.? This statement is false to the point of being pure nonsense. As previously noted, Hibben (1943) stated: ?The deposits known as muck may be definitely described, in the opinion of the writer, as loess material. All characteristics seem to indicate a wind-borne origin from comparatively local sources, as the material resembles local bedrock. The outwash plains of the local glaciations are likely points of origin for this material. These mucks deposits are from four to one hundred feet thick and are especially well known in the vicinity of Fairbanks, Circle , and other gold mining centers of the Upper Yukon and the Tanana where the muck overlies auriferous gravels. Muck deposits of considerable thickness, however, are found in the lower reaches of the Yukon, on the Koyukuk River, on the Kuskokwim and on several places along the Arctic coast, and so may be considered to extend in greater and or lesser thickness over all the unglaciated of the northern peninsula. " As Hibben (1943) clearly states above, his ?muck? deposits underlie large parts of Alaska. It is clear that the extent of the deposits, which Hibben (1943) called "muck" covered far too much area for hydraulic mining to have destroyed them. Although the original outcrops would have been destroyed by hydraulic mining, these deposits are extensive enough, according to Hibben's (1943) own descriptions, where hydraulic mining would only have created new outcrops as it destroyed the old ones. In the same paragraph, Hibben (1943) states: "In addition to amorphous bodies of loess material, the muck contains interbeddded volcanic ash layers, lenses of clear ice and peat, and abundant animal and vegetable material, the whole frozen into a solid mass." Comparing how Hibben (1943) describes what he calls "muck" and what Dr. Pewe, Muhs, Westgate and many other Quaternary geologists have published in the 60+ years since 1943 it is quite clear that the so-called Alaskan "muck" includes what is now known as the Engineer Loess, Goldstream Loess, Ready Bullion Formation, and other stratigraphic units. These and other stratigraphic units, which are described in the in modern literature, consist of the same loess and related sediments that overlie the gold-bearing, "auriferous", gravels, which contain peat beds, buried "forests of trees", volcanic ash beds, vertebrate fossils, the mummified animal remains, permafrost, and so forth, which comprise the "muck" of Hibben (1943). The deposits described by conventional geologists even contain the same "canyons and arroyo cuts" filled with "twisted and torn trees piled in splintered masses" as noted in Hibben (1943). There is enough of a significant and a striking correspondence between the deposits described by Hibben (1943) and those studied in next 60+ years to see that they are clearly the same deposits. They found that certain aspects of deposits to have been grossly exaggerated and misrepresented by Hibben (1943). Finally, although the original outcrops, which he examined were destroyed by mining, it does not make any difference as it is nonsensical to argue that either impact generated mega-tsunami or other related catastrophe large enough to wipe out entire species is going to create a deposit of such limited extent that they will be wiped out by a single mining operation. If these deposits were truly the result of some sort gigantic cataclysmic event, they would blanket the countryside to the extent that no amount of hydraulic mining could destroy them. The fact of the matter, is that the deposits studied by various geologists and archaeologists in the past 60+ years are the same deposits, which Hibben (1943) studied, even if some of the outcrops have changed as a result of hydraulic mining. As far as I am concerned, the implied claim that there is no evidence for the catastrophes, which Dr. Hibben talked, because hydraulic mining has destroyed them makes as much sense as the "dog ate my homework excuse". Mr. Geodine continued: ?Taking Paul's claim at face value, the puzzle here is why (sic) Gibben's would intentionally lie about what he saw, when those who were there with him at the time were still alive. For that matter, why would he report something so extraoridnary in the first place? The man was a leading archaeologist.? The fact of the matter is that contrary to what Mr. Geodine states above, I am not the one, who is claiming Hibben faked his research. As noted previously, it was geologists, archaeologists, and paleontologists, who worked closed with Hibben, who accused him of fraud as discussed in detail by Preston (1995). Again, I am not accusing him of intentionally lying. I am just saying, as he did with the sediments and psuedoarchaeological site that he found at Chinitna Bay, he was sloppy in his observations and descriptions concerning the Alaskan ?muck? and being completely unfamiliar with loess, permafrost, and periglacial processes, he completely misinterpreted, what are now recognized as typical normal periglacial sediments, to be the result of ?extraordinary? catastrophic processes. Having done PaleoIndian research in the hot and arid climate, he was simply quite ignorant of how to interpret the sediments, which he briefly studied in the cold Arctic climate of Alaska. References Cited: Preston, Douglas, 1995, The mystery of Sandia Cave. The New Yorker. vol. 71, pp. 66-72 (June 12, 1995) Mr. Geodine wrote: ?On the other hand, given the use others have made of Gibben's reports, I could understand why his observations would be "questioned" by later researchers. I doubt that those studies were "unbiased". As noted above, Mr, Geodine is completely wrong in thinking that the controversy concerning Hibben?s research has anything to do with his catastrophist ideas. Preston (1995) has documented in great detail that the allegations about fraud on the part of Hibben are almost entirely related to his research at Sandia Cave. His research at Chinitna Bay is disputed because the sediments, in which he found his alleged Paleo-Indian site and mammoth remains were found to be 9,000 years too young to have contained them. Although the precise locations and strata, at which Hibben (1943) allegedly found his artifacts and mammoths, were located with absolute certainty, Thorson et al. (1978, 1980) found neither the artifacts nor fossil bones, which Hibben described. All they found were recent whale bones. They discovered that Hibben was even wrong about his Alaskan ?muck? outcropping along the shore of Chinitna Bay. It is quite clear that Hibben was quite clueless about what he found in Alaska and, as a result, grossly misinterpreted both how old it was and how it was formed.
