Totally the opposite situation. Once amateurs found the respective sites and notified the proper authorities, action was taken with the Dead Sea scrolls and was not at the Chobot find. The difference being that the scrolls were recognized as valuable and the Chobot site geofacts were not. It took legitimate time to piece together the 10s of thousands of fragments of some of the scrolls and decode them properly.

Old story, pet peeve. . . ;-) Right, this may be of some interest to you if you haven't seen it before.... http://www.friendsofpast.org/forum/mother.html "It has been estimated that between 60 and 75 percent of work completed in the field by professional archaeologists is not reported." Now, supposing this is true, take those that are reported and consider the ones that contain directly contrary evidence or opposite conclusions drawn from the same data. Then consider the few that contain errors that aren't noticed because the other 60 to 75 % haven't been reported. Now what are you getting for your dollar? > > Regards > bk

OK, so there is three of us, so far, that are not impressed by the "alleged" artifacts. But even if we are wrong, it still would leave this tremendous gap in proficiency between those "alleged under the moraine" and those found higher where there is no doubt that they are legitimate artifacts. Another words, why would these first pioneers to the Americas suddenly revert back to 'worse than Oldowan' lithic capabilities in total? To be sure, in many given sites, there will always be a certain amount of junk found with the legitimate material. But in this case, with all of the hundreds of artifacts found, none at the early level are unequivocal artifacts. This alone puts a strain on my imagination. > He also indicated that their respect for The Mammoth Trumpet > plummeted when that article appeared, as they felt that it was > one-sided, ill-informed, and contained some errors of fact, > partly because The Mammoth Trumpet never contacted them before > that story appeared. In all fairness to the CFSFA, even when they do print junk, it's my opinion that they will print counter views if they are sent to them. They really can't publish the other side of a controversy if they dont have it (but yes, they should have checked this one out further before printing that story). In the case of your Alberta Archaeological survey guy, it sounds like he figured the whole thing was such a joke it wasn't worth his time to respond to MT. > The story refers to a lack of funding being the problem stopping > further investigation; in the case of the Survey, it seems that the > major reason they did not investigate further was that they had > higher-priority sites to investigate.

Oops, I did send you the pictures (w/o the text) just after your last post. I did not receive a 'can not deliver notice' so I assumed you did get them. A few days later I received three cannot deliver messages (they bounced because their mailboxes were full) from people who I don't know, and certainly didn't send any emails to. One of these returned messages had a attachment with a virus that my anti-virus software picked up, one was just a simple request for information with no attachment and the other I just deleted.

Don't know if it applies in this case, but there are precedents for loss of technology by AMH in extreme environments. Jared Diamond in Guns, Germs & Steel discusses e.g. Tasmanian aborigines & Chatham Islanders (hunter-gatherers descended from New Zealand Maori - Chatham Islands are SE of NZ). As re the Tasmanians, after being cut off from the Australian mainland by rising sea levels ca. 10KYA, their population declined from perhaps 50,000 to 5,000, & their toolkit became greatly simplified (e.g. lost the skill of making ground stone tools I think. Can't recall the exact details.) One interesting aspect when whites arrived was a major cultural taboo against eating fish. Diamond suggests that with such a low population, death by drowning was too great a risk, so they gave up fishing. Not totally sure I accept this argument but it's interesting anyway...

Val: If they're pics from the Mammoth Trumpet article, I don't think that you'd be missing much. Some of the 'artifacts' seem to be quartzite cobbles with impact scars entirely coincident with fracturing by glacial action, just like you'd see in lots of gravel pits where they're mining preglacial gravel, e.g. Tertiary hilltop deposits, terraces and valley fills. I've seen similar fracturing in situ in a pit face,and one pit near Villeneuve (NW of Edmonton, in buried-valley fill) had fracture planes that extended through multiple beds, with fractures in individual cobbles and pebbles lined up with the fracture planes. It is likely that some of the 'artifacts' were quarried by glacial ice out of old North Saskatchewan valley fill or from an old river terrace, then transported some tens of kilometres SW or SE to Buck Lake, and fractured either in original position or along the way.

It was not unusual for Clovis to flute preforms, but this means the finished point would have ended up even smaller. The Chobot fluted preform/point(?) is simply too small to be convincing. A fluted point was found at the Charlie Lake site in northeast British Columbia, that is thought to be younger than Clovis, and Charlie Lake is considerably north of the Chobot site.

I was referring to the age of the legitimate artifacts pictured in the MT article as 8-10 kya, which seem to be of the Western Stemmed Tradition. There are classic Clovis finds in the southern part of the corridor and Clovis-like and stemmed points as far north as Charlie Lake (all poorly dated). Then there is a gap of 'old sites' between Charlie Lake and Bluefish Caves. >Or is the site at Taber older than that? Taber is too controversial for me :-) > > Val

Okay, forget the slab-excavation-and-relocation possibility for the origin of Buck Lake. It's not likely. What happened with Buck Mountain, to the north of BuckLake, is about a square mile of sandstone bedrock froze onto the bed of the glacier above, tightly enough that when the glacier advanced (temporarily, in the general retreat of the ice margin) that slab was moved to the southwest, up and over the sandstone bedrock infront of it, leaving a sandstone hill overlooking what would later be Buck Lake. I should not have mentioned the somewhat unlikely possibility that Buck Lake was where a similar slab used to be before it was removed by the same sort of glacial action. The Buck Lake basin may have been enlarged and deepened by such an action, but it is in line with a mapped preglacial valley, so we should just consider it to be a low spot in that preglacial valley trace. That's the most likely explanation for its existence. I'm sorry to have been a source of confusion. <snip> > These areas that we have been talking about, were rapidly populated shortly > after the glaciers retreated.

Flames go!) :) Val: Superfan phones a radio station talk show, apologises for his very low, hoarse shouted-out voice, and intones in a basso growl, "Go, Flames, GO!" Somebody immediately calls in and asks why they are putting through calls from the Prince of Darkness. Daryl Krupa
