Pat Garrow It is now 9 PM by my watch, and time for the first Articulations chat to begin. Thanks for joining us tonight. We are going to record the chat tonight so that people who miss it can come back and read a transcript.
Pat Garrow For the record, our guest is Dr. Tom Dillehay of the University of Kentucky, to talk to us about the Monte Verde site
Pat Garrow I am going to start with a few questions for our guest and then open it up for your questions
Pat Garrow Tom, thanks for joining us tonight, would you tell us a little about yourself?
Tom Dillehay I was born in the southwest US, starting doing archaeology. at age 13, and then headed for South America while an undergraduate student
Pat Garrow Tom, how did you become interested in archaeology?
Tom Dillehay I lived next door to Alex Kreiger once and also involved in an avocational-professional. society. I was hooked early
Pat Garrow Alex Krieger would be quite a neighbor. Did you become involved in any of his digs?
Tom Dillehay I once worked in Texas with Kreiger, Dee Ann Story, and others. It was a Caddo site
Pat Garrow Good way to start. I understand the Monte Verde site was found in 1976. How did you become involved with that site?
Tom Dillehay At the time I was teaching in Chile; one day bones were found in a distant place; I later checked it out, thinking it was a Paleoindian site
Pat Garrow When did you start to work there?
Tom Dillehay We worked there in 1978 for the first time and ended in 1987
Pat Garrow I would like to throw the chat open for questions at this point
nali I have a question..
Pat Garrow Go ahead, nali
nali I was wondering at what point in the excavation did you first realise that you were most likely dealing with a site that predated Clovis?
Tom Dillehay In 1979, when several geologists who worked in the region looked at our stratigraphy and said it was at least 12,000 years old
Pat Garrow But you carefully avoided the pre-Clovis label for quite a while didn't you?
Tom Dillehay I was not interested in the Clovis:pre-Clovis debate but only the adaptation of people to the forest around site. Later, once the site was cast in pre-Clovis light I felt it was unfortunate because that became the only way to discuss it
Flagman Other than the age, what's the most unusual thing about Monte Verde?
Tom Dillehay The preservation. Marvelous
Barb845 Did the people impact the forest?
Tom Dillehay We think so. Pollen and other ecology records suggest humans caused more fire
jharder Do you think the increase in the incidence of fire was due to "accidents" or controlled burns?
Barb845 Did the people-induced fire change the botanical mix?
Tom Dillehay We don't know; perhaps both. Geologists tend to think it's more likely to have been accidental
Tom Dillehay The botanical mix was definitely changed in terms of vegetation structure
calico Dr. Dillehay: Why do you say ..."unfortunately it became the only way to discuss it."
IreneH1 I was just about to ask the same..
Pat Garrow There seems to be some interest in why the pre-Clovis designation was so controversial. Do you want to try to handle that one Tom?
Tom Dillehay First, let me answer the previous question. I say unfortunate because I think the debate distracted from solid evidence and method used
coop Tom, what do you think the best way is to get private landowners to earn the trust of the professional community, so that more pre-Clovis sites are properly documented, and shared with all?
Tom Dillehay More public talks and more public outreach by archeologists.
Tom Dillehay As for pre-Clovis term, Junius Bird long ago stated that the South American data was clearly Clovis. He did this in the 1950s. Later we see more than Clovis, and this raised much debate
toad Do you think the site would be important regardless of whether or not it is pre-Clovis? Why?
Tom Dillehay I think the site would be very important without all the Clovis discussion. It is like the Ozette site in the northwest; the preservation is very good.
Pat Garrow It's quite rare to get wood, bone, and even flesh preserved on any site. how did you deal with so many organic remains?
Tom Dillehay We had chemical preservatives and experts on site
Pat Garrow sure would need them! incredible preservation
mohr On a more personal level, Tom, what were your thoughts when the archaeological world went from "Monte Verde?" to "Monte Verde!" Was there a sense of relief?
Tom Dillehay Yes, there was some relief among all of us. the team includes more of course.
IreneH1 This may be a naive question: Was this the first "pre-Clovis" site found?
Tom Dillehay First pre Clovis site. Don't know. Maybe some of the surface sites found by Kreiger, which he thought were pre-Clovis in 1964.
calico Many of us think there are acceptable pre-Clovis sites in the U.S.
nali My understanding of the situation with Clovis was that from Central America going north, the remains are largely Clovis, and going south they appear to be Fishtail, but with many similarities between them and a kind of meeting in the middle so to speak, but with neither consistently dating older than the other
Tom Dillehay nali: you are correct. South America is very different.
Aulus I may have missed it as I was late arriving, but has there been any human organic material found and enough to do any DNA testing so as to compare to existing populations?
Tom Dillehay No human remains officially found, meaning we had a human bone but it was shipped to a lab and lost there in 1979. We are working on DNA matter still but we have lots of problems with it. It's old stuff; and the older the bone, the harder it is to get acceptable DNA.
coop Has "lost info" been a frequent problem?
Tom Dillehay coop: only with the one bone.
IreneH1 That must have been frustrating though
calico any human hair?
Tom Dillehay A few but very degraded.
Pat Garrow Monte Verde was not only an extremely complex site, but it was excavated over a course of years. Did that cause problems?
Tom Dillehay Yes. we had to protect the site, re-invite colleagues each time, and pull together and add to the research team.
Pat Garrow Also, excavation and recordation methods have changed over the years as the field has matured. That must have caused some problems
Tom Dillehay It did. For instance, at first, we knew nothing about how to prevent contamination of DNA matter; then we moved from piece-plotting by hand to finer instruments in later years. etc.
Pat Garrow In contracting we rarely spend even 6 months of a single site. problems must have been daunting
BobOconee Is the Monte Verde site currently being excavated and if so what is the direction of study?
Tom Dillehay The site is not being excavated at present. The Chilean government is building a site museum. We plan to return for the deeper possible cultural level next year.
calico Is that the stuff which might be dated as old as 34,000 years?
Tom Dillehay Yes.
Tom Dillehay Current direction of work: I am working in Peru on early and late material. Also have students working in various areas.
calico any coprolites?
coop Tom, have you seen much in the way of bone tools of preClovis age?
Tom Dillehay Coop: I have seen early bone tools in South America, mainly Argentina. They are flakers.
coop flakers?
Tom Dillehay Bone flakers for working unifacial pebble tools.
Pat Garrow How long was your typical field season on the site?
Tom Dillehay Pat Garrow: Most field season lasted 2 months. We lived in tents and cooked out; about 20-30 people.
Pat Garrow That is a decent amount of field time. I admit I would rather camp out at Days Inn myself though
nali Pat: that's no fun!
Pat Garrow is at my age nali
nali hahaha
IreneH1 ==sympathize==
Tom Dillehay It was fun though taxing. We always had a large campfire, a little pisco (Chilean brandy), and lots of guitarra and singing.
BobOconee Tom your findings at Monte Verde didn't fit the old theories of early man. Did you personally feel any pressure to conform?
mohr Further to BobOconee, Where do you think we are going in terms of the first peopling of the continent. Was it Lee who was talking 100kya in the far north? He was ridiculed, but the door seems to be open now.
Tom Dillehay Mohr:100k seems far fetched. I think we may see 20K but I would be very reluctant at present to push farther back. We need more work from various disciplines.
mohr Amen to that, Tom
Pat Garrow What are the Cactus Hill dates?
Tom Dillehay :I think Cactus Hill is around 16K, though, as one might expect there is question about the context and association.
Pat Garrow I have more questions about Cactus Hill than Topper, but no decent Topper dates yet
Tom Dillehay pat: Agree. Need dates from Topper. Topper looks good. Goodyear and Co. has done well there.
Flagman I never heard of Topper. Where is it? Anything published?
Pat Garrow Topper is a pre-Clovis site n South Carolina being done by Al Goodyear; the work is in progress
Pat Garrow Have you seen Al's features at Topper, Tom?
Tom Dillehay : I have only seen photos of the features at Topper.
Tom Dillehay They look good.
Pat Garrow saw slides a couple of weeks ago. incredible
Pat Garrow The features at Topper are piles of raw materials with some burin blade tools
Pat Garrow I noticed that the lithic assemblage from Monte Verde was rather slender. Is that typical of the early South American sites in general?
IreneH1 What different disciplines do you usually have on your team?
Flagman You've said Monte Verde 1 had good stratigraphy, good radiocarbon dates, good tools. Why not accept it and say 33K?
Tom Dillehay Flagman: I have been questioned about not accepting the 33K data; first, it bothers me that people could have been here that early. Second, I am not fully convinced that the fire pits are human made. That sheds some light doubt on other things.
Pat Garrow What could explain the fire pits Tom? burned trees?
Tom Dillehay We excavated control areas that showed no similar data. Appears not to be burned trees. basin are round a shallow. Also contain zinc and other compounds not with trees.
IreneH1 How big were the fire pits?
Tom Dillehay Size of fire pits: about 20-30 cm in diameter and 2-3 cm in depth.
Rich In terms of the geology, how deep do the productive strata go, and how far do you intend to go with the dig?
Tom Dillehay The productive levels undulate but most productive at 12.5 k are about 1.2 meters deep. Top soil has eroded. The deeper material possibly cultural varies from 1.8 to 2.0 meters roughly.
calico any red ocher and/or quartz crystals (worked or unworked or with Paleoindian "bag wear"?
Tom Dillehay calico: no quartz crystals but there was red ocher
ddetr Isn't there something in western Pennsylvania, also?
mohr That would be Meadowcroft
Pat Garrow What about the shelters at Monte Verde, Tom? How were they constructed?
Tom Dillehay They were constructed of wood and draped with hides. There were small braziers or pits scattered through them.
calico Have you thought of trying any sediment thermoluminescence dating on your sediments?
Tom Dillehay I am exploring the possibility of TL dates on sediments.
Pat Garrow Goodyear has done that at Topper, Calico
calico I've used Sediment TL on sediments at Calico with good results. I like it.
Pat Garrow seems to have worked for Goodyear too calico
mohr Is there any sort of cultural continuity between these sites? Can they be related back to a particular pulse and associated with any modern First Nations family? If you accept Glottochronology, some of these language groups can be "backdated"
Pat Garrow I have read Feidel's and others critiques on Monte Verde, and personally don't feel they have much of a case, but would you like to address this Tom?
nali It looks me like Feidel never bothered to fully read the reports. His concerns with artifact numbering etc were all addressed but he persisted in attempting to discredit the finds using that as his driving force
Tom Dillehay I would expect some critiques. After all, some people's careers are shaken a bit and others see the opportunity to create a bit of light for themselves. All of this is healthy as long as it is done fairly, professionally, and openly, which was not always the case.
Tom Dillehay Feidel saw what he wanted to see.
Pat Garrow I felt some of the criticisms were unwarranted to be sure Tom
nali Are you referring to his choice to publish in a non-juried journal?
Pat Garrow in fact, most of them
nali I agree Pat
Tom Dillehay nali: yes, but others issues too, such as sending copy of critique before publication and having professionals review it before publication. That is why matters are peer-reviewed.
Pat Garrow One of the strengths of archaeology is that we air our disputes in public, in same cases that is also a weakness, as it allows some to crawl onto the backs of others to achieve a little fame
Kris Hirst It's a problem, in that the public wants to know what we find out, but the mainstream press only understands very shallowly what we say.
Tom Dillehay I think most critiques are well-intended and very useful, if one properly.
Pat Garrow Absolutely true admin. archaeology is hard to reduce to sound bites
Pat Garrow Constructive criticism improves
IreneH1 Some press more adept at it than others... ;-)
Kris Hirst and the Monte Verde thing was too complicated to put into sound bites. I know, I tried, and failed.
Pat Garrow true Irene
Tom Dillehay The press. Now that is an issue. Too much important archeology is played out through the press. This is very advantageous in many ways but dangerous in others. We often are said to say something we don't mean, and then defend it later.
Pat Garrow all of us have been there Tom. We have one of the best science journalists in the country here in Atlanta and his stories are accurate and interesting, but that is rare
Tom Dillehay So true. I know CRM archeologists have to deal with much of this in the public eye. I did a lot of CRM work and occasionally still do.
Flagman Need to have some large role for popular press. People deserve to know.
IreneH1 What about the New York Times?
Tom Dillehay I have nothing but accurate reporting from the New York Times.
Pat Garrow The secret is to try to feed reporters accurate sound bites, as hard as that is
IreneH1 Good! :-) It's my home paper, so I tend to get my news there first
Pat Garrow NY Times has done well by me too
Kris Hirst But even the NYT has an agenda, and only publishes the "exciting" sites; if Monte Verde hadn't had those early dates, they wouldn't have published the site.
Tom Dillehay Probably true.
Kris Hirst No doubt about it, John  Noble Wilford is a terrific science reporter.
mohr Reporting archaeology is also difficult, though, because one does not necessarily want to give away the location of a site, yet needs public interest and funding. That is a problem inherent to the practice.
Pat Garrow That is the critical point Mohr
Pat Garrow Most of what we do in CRM is not revealed to the press
Kris Hirst Irene asks what is CRM; it means Cultural Resource Management and is the federally-supported arm of archaeology in the USA.
Pat Garrow it is the source of employment for many of us Irene
IreneH1 Good! May it flourish, Pat!
Pat Garrow my thought exactly Irene!
Wayne Coming from the opposite direction of sound bites, Tom, have you found that your book has enlightened many others on the differences between archeology in north vs. south America? I know it has for me.
Tom Dillehay Wayne: I hope so. There are major differences. The most significant is the unifacial industries down south, which are very similar to those, curiously in Australia. Glad the book helped.
jharder Tom, you indicated that you are currently working in Peru. What led you there?
Tom Dillehay I did my Ph.D. work in Peru and have worked there every year since. Perhaps because the sites aren't so early few people know about this aspect.
Pat Garrow what types of other sites have you worked on there Tom?
Tom Dillehay : My initial work was with large Inca sites; later with Archaic and Formative (Woodland like) sites.
Pat Garrow interesting path to early sites Tom
calico Dr. Dillehay, any comments regarding the passing of Scotty MacNeish and his work in Peru (or at Pendejo Cave or elsewhere)?
Tom Dillehay I knew Scotty well. He attained the maximum-hard worker and hard player. He was a great archaeologist; he had a good nose for the insightful data, albeit in later years his methods fell off a bit. As for Pendejo, I have problems with it; nonetheless, there are things (clay fingerprints and exotic pebbles?) that puzzle me. I hope the site is published.
Pat Garrow hard to put humans in Pendejo as early as Scotty thought in my opinion
jharder Why did you decide to move from the Inca to the earlier sites?
Tom Dillehay The decision was made for me; Monte Verde came to me and I decided to test the site.
mohr 'scuze me, but what are the Pendejo dates?
Pat Garrow over 30,000 aren't they?
calico yes
coop 50k
mohr That's dramatic
calico We have other sites in the U.S. that date even earlier
Tom Dillehay Pendejo dates vary, depending on what you date and read; they can go from 25 to 40k or more.
Pat Garrow You said earlier that you think the arrival of the first people in the Americas will eventually be pushed back to 20k Tom. What do you think the earlier assemblages will look like?
Tom Dillehay Pat Garrow: Don't know. It seems clear that unifaces just are not prevalent or non-existent in North America. Of course, they may exist in very small numbers but we don't "see them". The earliest assemblages may indeed b like what you see at Cactus Hill and Topper and lets not forget Meadowcroft. .
Pat Garrow the Cactus Hill and topper assemblages look very different from what I understand. must beg ignorance of the early occupation at Meadowcroft beyond knowledge it exists
calico We have old unifaces of the "Lake Manix Lithic Industry" on the surface in the Manix Basin of the Central Mojave Desert of Southern California (near Yermo)
IreneH1 And at what k level does it become problematic?
coop why quit excavating at 12k?
mohr once again, is there any evidence to tie these sites together in the same sense that we discuss Clovis?
Tom Dillehay Mohr: No, not like Clovis which is tied together by a narrow range of dates and a very clear diagnostic point. But Clovis may be exceptional. If one looks to other areas of the world, Korea, Australia, parts of China etc, there is no clear-cut early or first culture with a nicely defined diagnostic like Clovis. Let's face it, some early cultures may have been more diversified and less formalized than we thought.
nali yes, and they may not all have been successful either. A lot of the time we look at these collections and try to establish some kind of continuity where it just can't exist
Pat Garrow I understand there are some formal bifaces from Cactus Hill that may be ancestral to Clovis. Have you seen any of those Tom?
Tom Dillehay I have seen some bifaces from Cactus Hill. Some look roughly similar to the deeper bifaces in Meadowcroft and, in some ways, represent the kinds of lanceolate-like points that should be early.
Kris Hirst What's your opinion about Dennis Stanford's theory about colonizing across the Atlantic?
nali I was going to ask that same thing Kris.. the solutrean connection
Tom Dillehay On Solutrean culture; Not yet convinced but willing to keep the door open a bit. I know the Spanish lithics; there are similarities but also many differences.
coop How to explain the differences across such a long distance
coop And the similarities....
mohr and it seems that differences are a more useful point of comparison than the similarities
coop America and Spain
IreneH1 Couldn't one expect similar but separate developments?
Pat Garrow That would be quite a link. a possible eastern or southern origin for Clovis
Wayne Dr Dillehay - have you seen anything coming out of the Gault site in TX which holds promise for a better understanding? like the engraved pebbles, ...
Tom Dillehay Wayne: I have seen some things. The engraved stones are roughly similar to some Solutrean-like marked stones. I wish to say that Mike Collins at Gault, Denis Stanford and Bruce Bradley with the Solutrean model; I highly respect all these individuals; moreover they are friends. But, remember that Betty Meggers about 40 years ago thought that Jomon people came to the Americas to establish early culture. She based her work on a few similarities..
Pat Garrow Morphological similarities of early pottery as I recall
Tom Dillehay Yes.
Pat Garrow David Chase did a lot of the early work in Japan that documented the Jomon pottery. he still lives in the Atlanta area
coop How about the Onion site engraved Clovis stone -- 40 lbs.
coop Hester documented it
mohr Onion...are they petroglyphs?
coop It's like the Gault stones, only many times larger
Wayne Yes, thanks. The analysis of all these artifacts is still in the early stages.
Weaver Dr. Dillehay; If people across space and time are using similar resources, for similar tasks, wouldn't there be certain about of repetition of techniques and styles? Lithics especially constitute such a small percentage of a people's technology, don't we need something more ?
Tom Dillehay I agree. But environmental differences and change resulting from time and space drift creates more differences, among other factors. We need much more than stone tools--like organics.
mohr A Lazlo Szabo at the University of New Brunswick has published interesting work favourably comparing the Algonkian language with Finno-Uraic(?) I guess we all came from somewhere.
calico Dr. Dillehay, how did you feel about the fact that widespread acceptance of your 12.5 ka 14C evidence came after the visit of some of the major pre-Clovis skeptics and not before?
Tom Dillehay calico: I and others with the team felt good--thinking that too any years had passed.
skeptic1 I was intrigued by the earlier suggestion that artifacts from MV and other unifacial industries in South America resemble Australian material. Are you suggesting that there is a genetic or culture-historical connection between these areas? If not, what is the potential homeland for the 20,000 BP immigrants? It could hardly be Siberia, where there are mainly microblade and biface industries throughout the Upper Paleolithic! (Sorry about the foul-up, folks)
Tom Dillehay skeptic1: Not suggesting any formal linkage between S. Amer. and Australia. though some Aussies believe so.
calico Dr. Dillehay, thank you for being in this chat room. Best of luck with your on-going research. If you ever find yourself in the Mojave Desert, stop in at the Calico Site. we have good artifacts and good dates
Wayne Thanks all!
mohr I'd just like to thank Tom for letting us pick his brains for a couple of hours.
calico yes, thank you and good night
Pat Garrow Looks like it is time to let Tom off the hook. Thank you do much for joining us for the first Articulations, Tom, and thanks for you patience.
Tom Dillehay ArcheologyADM: thanks.
toad this has been very interesting - thanks to all
coop I'll be back, thanks all
calico let's do this again some time
IreneH1 Indeed this was quite interesting to a lay person like myself
mohr Okay, who's for a beer?
Tom Dillehay Thanks everyone for the good questions.
Kris Hirst Thanks to you all for a tremendously successful evening, for the first Articulations. Next week, look for Anita Cohen-Williams, one of the pioneers of the electronic media in archaeology.
Kris Hirst Count me in, you buying, Mohr?
mohr Sure, we can bill it to the Smithsonian
Pat Garrow I hope this is the first of many. Thanks again to Tom and all who attended
Tom Dillehay Pat Garrow: thanks for the invitation. Bets of luck.
Pat Garrow thanks Tom, and same to you as well
