Re: update on progress in Bartron village site (21GD02) excavations.
To"the Tribal Council and to Xcel Energy:
We againextend our deep gratitude to the Prairie Island Indian Community and the Tribal.Couneil for your years of support in our continuing research. on the Native American occupations on and around Prairie Islan& We also gratefully acknowledge Xcel Energys cooperation and .support in the Bartl-on viltage research project this year. There are too few examples of this level.of cooperation across -
communities, and we. thank . everyone. - involved for their patience, and sensitivity..
The Red Wing region is of immense.importance in understanding the foundations of historical Indian life stretching from the eastern woodlands out onto the prairies and. plains and from the central Mississippi .
Valley up to the northern lakes. Here, the great nations we now know as the Dakota, Ho-chunk, Ioway, Otoe, and Missouria, among others,.lived, met,. feasted, prayed, traded, married, raised their children, and died..The sites they left .behind .are central parts Of Indian cUltural history and are important to all people as our common human hi story . Archaeological research~isone of the only tools we have to. study.
ancestral lives, and along with .oral history and.oraltradition, it helps us remember, learn from, and honor the past..

Among the major village sites in the Red Wing area, the Bartron village has long remained too poorly understood. Excavations conducted there from the late 1940s tO the late 1960s have never sufficiently been. tied together for us to understand the site as a whole, and indeed there are many questions that were either never answered or in some cases, even asked in the first place. The work we began this summer is designed to provide a basis for addressing some. of these asked and unasked question, and to provide a more synthetic overall impression of the site.- its boundaries,, components, andcondition. Since our analysis is not yet complete, this letter merely gives you some initial information. Please, therefore, .
consider it preliminary and subjectto change as our work progresses, and exclusively referential to the Bartron village site.
What is. talked about here is primarily about the archaeology field school.. The geophysical survey done by Don Johnson is under specific .contract with Xcel and will be reported separatelyi What I can say is -

areas. The field school goal was .mostly to assess thepotential for contact-era .occupations at the site,, and to investigate a particularly important .feature that Elden Johnson called a "possible wall trench" in his 1968 work. The information here..will be expanded and revised as Emily. Hildebrant completes her.MS "

Assessment of previous work " ..
Although investigation of the Bartron site goes back. at.least to the turn of the 20t~ Century, scientific excavations therebegan in 1948 under the direction of Dr. Lloyd Wilford. Wilfords Work, though,.was co ~ned to the cultivated field now owned by Mrs. Charles Suter, and is not germane here. The specific.
work that is relevant to this years field activities is Elden, Johnsons excavations .in. the 1960s.-.
Please not¢ that I do not. wish to impugn Dr. Johnson or cast doubt on th¢ results of his total .body of work..He was a pioneering figure and a fm~ archacologist, and many. of the states s~nior..archa¢ologists today were train¢d.under his tutelage. Indeed, he was among the first archaeologists in Minnesota to .
.stress. the importance of working with descendant communities..HowCwr, it must be acknowledged that some o.fhis methods would not be considered acceptable today. For ¢xampl¢, in 1969 at theBartron.
village site .he had a mechanical grader operator strip th¢ upper 60cm of a 15m by 20m area that he knew to be intact (that is, ufidisturbed). His goal in this Was to look for deep pit features because, in other areas of the site, hc had found particularly important and impressive specimens of pott¢ry,.stone and bone tools, etc. In doing so, :he undoubtedly destroyedother important .information. This would NEVER be done today, and it breaks my heart, to know that it was done then. Yet, at the .time it was considered an acceptable action,, and it Was donein good-faith.. As. well, as you will note below,the results of Iris 1968
.work would have been different if he had not run out of time. His aborted.effort to determine the existence ofa possible wall trench led to a.significantmispercep.tion .in the literature that the current proj.ect can finally correct.
Overall, my assessment .is that he was overextended. He had t0omany students in the fieldand too many excavation traits open at one.time to see and deal With all ofthe .features .andartifacts. that were being....
documented .and. recovered. In addition, his and the students field notes and maps leave many details quite.unclear. Again this waspar for thetime and is not a real criticism of him, but rather of State of the "
- discipline in the late 1960s,
.,
History of investigations and status .of data Although we have some information on the site excavations that took place in 1948, 1968, and .1969,. we also know that limited excavations took place in 1960, 1967, and 1980. As.yet, no field notes, maps, or reports ..have been found that provide details, on the 1960 or 1980work. There are field notes from the 1967 work, but no map has been located and thus the excavation uni. ~ts cannot be tied..to any real world -
coordinates, or. to other excavations atthe site. With specific regard to the 1980 work, the detailsmaybe included With other data on that years work on Prairie Island, but.this has yet to be determined.
The artifact collections of the Minnesota Historical Society (MHS)include materials from the 1948, 1967, I968, 1.969, and 1980 investigations, but. the whereabouts, of the 1960..artifacts is unknown. The original field maps from Wilfords t948 work seem to be lost,.although some data on the location of the excavation units is contained inthe student" s field, notes (interestingly, Elden Johnson was the mapper that year) and maps were prepared for Marshall MeKusicks 1950s MA thesis at the University of.
Minnesota. The MHS has.graciously lent us the original, hand-drawn excavation maps from the 1968 and 1969 work so that we cancompletely redraft a proper map (the map presented in Gibbon 1979, the only published map,.has some major errors and omissions). All in all, the records are in comparatively good "
and complete shape, with some notable exceptions. Finding the.missing notes andartifacts remains.an important.goal of our work, and the MHS is assisting in this effort. -
Precontact components For many y¢ars,.amataur artifact collectors and professional archaeologists have known that the primary occupation at the Bartron villag~ was what. we call "Oncota".. This archaeological taxon, first used back
.inthe 1920s, is the word w~ us~ to coll~ctiwly describe the material culture. (ways Of making stone and~
bone tools and pottery) ~)f thos~ whom w~ now know to be ancesWal.Chiwer¢, but also som~ Dakota and Dh~gihaSiouan-speaking p~oplCs, itis not a wry useful t~rm an.ymor¢, but i~ is what .w~ hav~ to work.
with.
,.
Because of the. differences, in material culture seen. in the various Red Wing villages,, archaeologists have long puzzled over the fascinating dynamics of interaction among peoples from many separate Native American groups across.the region...Among thesevii!ages, researchers believed that the Bartron village most clearly contained the local expression of Oneota. culture, and was .probably ancestral to the Oneota
- - culture seen slightly later in the Blue Earth and possiblythe LaCrosse regions. The Oneota occupation at theBartron village gained, importance to archaeologists because, among the Red Wing villages, it seemed to be relatively early and. "pure"- that is, unaffected by what seem to be influences from other groups.
living elsewherein the Midcontinent. Non-local influences.are seen primarily at other large villages such as Mero, Bryan, and Silvemale.that date to a similar time - ca. A.D, 1100 - 1300. Johnsons description of apossible wall trench at Bartron was, therefore, particularly.significant because such structures were typical of Middle Mississippian culture, centered near St. Louis, Missouri, but were not typical of local-.
construction techniques. If present, it would be the only example.of a Mississippian wall trench .structure in the region.... Unfommately, even though Johnson was circmrmpect, this aspect of the site somehow became more factual than potential, and itentered the literature.
Radiocarbon .dateson Bartron site materials acquired at different times by Elden Johnson and Orrin Shane
.(then at the Science.Museum of Minnesota) were ambiguous,, suggesting either an early, ca. A.D. 1050, .or a late, .ca. A.D. i400 date for the site. This led to widespread speculation and debate in the archaeological
- "literature, especially because the origins of Oneota cuRure remain obscure. Some researchers suggest that Oneota culture is the result of non-local (i,e. Mississippian). influence on local, Late Woodland peoples starting around A.D.. 1050, while other researchers see culture change as a locally driven process
-happening .. independently of and prior to Mississippian influences spreading into the area. Thus, Bartron has become akey site in understanding the processes of culture ch .ange and the emergence of Oneota culture in the region.
One of. the. interesting .preliminary findings of our work at.the site .this year is. that there.appears to be -
more of a Late Woodland (ca. A.D. 700 - 1000) presence than suggested by earlier work at the site. Late Woodland occupations are pfimaiSly differentiated from Oneota occupations bythe pottery: Late Woodland pottery is tempered:with grit and decorated with Continuous bands of.textile and tool impressions, while Oneota pottery is tempered with crashed shell and decorated with discrete geometric patterns of trailed, lines and punctates. The reasons why we recovered, more Late.Woodland than Oneota materials at the .site this year are unclear.
.
We were fortunate to discover seven pit features (basin-shaped pits that Contain concentrations of artifacts and organic remains)., each of Which.we carefully excavated, importantly, the mystery of the possible -
wall trench, was solved by the. discovery of these pit features.. In excavation trait # 10 from the 1968 work, Johnsons students had excavated to 40cm in depth when he saw soil staining. To .Johnson, this suggested a wide, shallow trench extending to the northeast and southeast (that is, forming a fight angle). He "
expanded his excavation unit to the north and south.to try to. follow the pattern, but it was not apparent, and being out of time, he abandoned the effort. Upon re-excavating.the unit and digging a mere three centimeters deeper (to 43 cm), wefound that the soil staining was in fact due to the presence.of four large pit features, the tops. of whichhad blurred together in the soil.. Hence, therewas no wall trench at all and
we can now formally reject this as PosSible evidence.of Mississippian influence in Red Wing. This is an important clarification that has broad implications for Red Wing and Mississippian studies in general.
The functions of the pits is as-yet unlmown. The-soil was collected in its entirety and is being processed to recover even the smallestartifact (down to 0.25ram). There will. be adequate wood charcoal to acquire high precision radiocarbon dates of these features, and this will hopefully put to rest at. least some of the questions about the timing of the Late Woodland. and Oneota occupations at the site. Xcel Energy has offered to fund dates for two of the features following the protocols I established with Lawrence Livermore National Laboratory. This will be a very significant step forward in understanding .the site and in refining our tmderstanding of Native American.heritage

in the area.

Historical components " .. -
" .. ..
One of the most intriguing aspects of the Bartron site is the presence of what. are described as.."contact era" items such as glass beads, scraps of brass, and clay pipe fragments. Johnson reported finding such items in the 1960 and 1968 work, and he suggested that they may relate to the long-lost 1694-1696 fur trading post that Pierre Charles LeSueur established among, the Prairie Island Dakota. Importantly, when Johnson described the possible w all .trench,. he suggested that it was approximately a meter wide and had a closed comer, which would havebeen typical of Frenela-period outpost ccmstmction,. The contact
- period in Minnesota. lasted, from ca. 165.0 to 1850, and is one of ~e.most important and yet poorly known periods in Red Wing. archaeology.. In part .this is because it is a relatively brief time span, but also because the. artifacts are. quite rare and most of the contact era sites have since been destroyed by development.. (such as Chief Red Wings camp where the city of Red Wing now .exists). This period is ..
essential to studybecause it is precisely here that archaeology and oral tradition intersect.
As noted above, the.possible wall trench was not a wall trench, and therefore it clearly cannot be evidence of LeSueurs fort. Further, we recovered no artifacts dating to the contact era during this field season.
Thus, this component of theBartron site remains obscure but nevertheless fascinating and important to continue -
researching.. ..
. .
Condition and extent When Wilford began his investigation in 1948, he noted that part ofthe site was in a cultivated field .and part was in pasture. By the .late 1960s,the pasture had-grown into woodland, and by 2008, the woodland had become a dense forest. To facilitate the geophysical .and. archaeological investigations,. Xcel personnel cleared outthe underbrush. .All mature vegetation was left standing..The cultivated part of the.
field has beenunder continuous use.- Interestingly, although Johnson suggested that the wooded portion.
of the site had notbeen cultivated, our excavations did reveal the presence of a shallow plow,zone, in the soil. Itis therefore likely that the site. was cultivated for.a short period long enoUghbefore 1948 forit to have.become .a grassy field. This conclusion is supported by aerial phot0graphsdating from 1938 and 1949. -
..
Based on the geophysics and the archaeology, .we can conclude that the site is in good condition. This includesbohh the.cultivated and wooded portions of tlae village and associated mound go.up located to the southeast.. Although unapparent on the surface, the. locations of mound remnants, traces of houses and
.... refuse pits, as well as possibly a.palisadeor log wall, are clearly visible, The northern, site limits were" formerly drawn at where the old Nauer farm access road was, but the geophysics .indicates that the.site persists past that location..Further research using geophysical and archaeological methods should be undertaken in these.specific areas to continue to assess theextent .and character of the site.. Clearly, the village area and mound remnants that are in the cultivated .field will continue to be disturbed, and it would be.worth discussing some sort. of minimization efforts, such as no-till fanning, with the landowner..
Conclusions The research undertaken at.the Bartron village site this summer was successful in answering our research goals. Although we did not fred the French presence we were looking for, "negative" fmdings still give.
us information about the village, site. The project also attracted good attention to the importance of this
- work and of cooperation among researchers, descendant communities, landowners, and state and federal agencies..Our findings have already and will continue.to help.refine our knowledge Of Native history in the Red Wing..area, and.we.look forward to collaborating on future work. Please feel encouraged to ask any questions you may.have. We will be intouch again soon with further information.

- Childhood Cancer in the Vicinity ofNuclear Power Plants The 2007 "KiKK"* Study-IPPNW Physicians lssu.e Warning:
"Young children develop cancer more frequently when they live near nuclear power plants (NPP).
it has to be assumed that radioactive emissions from NPP stacks are indeed not as harmless as ,previously believed..
-Now it ,is time to act..
UIm, January 11~ 2008 Young.. children living near to German nuclear power plants develop cancer and leukaemia, more frequently than children living further away from. them. There.is a .60% increased rate of cancer and.. approximately 120% of leukaemia. These. are. the findings of the "Epidemiologica.i. Study of Childhood Cancer in the Vicinity of Nuclear Power Plants" (KiKK Study), commissioned by the German Federal Office for Radiation Protection (BfS). Although the design of the study, carried, out.by the Mainz Cancer Registry, i.s generally held to be correct,, interpretation of the studys findings isvigorously disputed by the authors~. Indications of an increase in the incidence of childhood cancer near nuclear power plants have been found for over 20 yearsz, but they have.not as yet .been. taken sufficiently seriously. The correlation has been unequivocally confirmed..bythe KiKK study.
Now it is time to act. -
Background to the 2007 KiKK Study The KiKK Study was called for i.n 200.1 by IPPNW and the. Ulm Physicians initiative in. a large-scale public relations cam.paign~, because several, studies carded out by Dr. Alfred KSrblein of the Munich Environmental Institute~, -including a study on NPPs in the Bavarian regioninitiated by IPP.NW- had shown a significantly higher incidence of childhood cancer in the proximity of nuclear power plants. Only after massive pressure and over 10,000 letters ofprotest to the authorities and ministries.did the. Federal Office for Radiation Protection (BfS) accept the necessity for further studies~. The study was then commissioned by the .BfS in 2003 to be carried out. by the. Mainz Cancer Registry~.
-
There had already .been reports of significant increasesin the levels of leukaemia around English nuclear, installations, in the 1.980s. There were also sharp increases in rates of leukaemia around the reprocessing, plants at Sellafield and L.a Hague.
An increased incidence.of ieukaemia found close to the. Kr0mmel. nuclear .power plant caused much concern from the beginning of the 1990s onwards. Few studies o.n the subject were. known,.
however, and most of those that existed Showed nothing conspicuous in the vicinity of nuclear.
power plants- at least in the official versions:
1992~ and 1997e - Two studies by the Mainz Cancer Registry (Director: Prof. Michaelis, institute for. Statistics and Documentation of the University of Mainz (IMSD)), covered the periods of 1980 to 1990 and 1980 to 1995 respectively. The childhood cancer rates in the vicinity of the 20 German nuclear installations (of which three. were decommissioned nuclear power plants and two were research reactors) were examined. Main finding- nothing conspicuous~.
.
,,KiKK" stands for ,,Epidemiologische Studie zu Kinderkrebs in der Umgebung von Kernkraftwerken" (Epidemiological
The "Michaelis" study has been consistently criticised since 1992 by Prof. Roland Schoiz-in numerous IPPNW~° ~ and other publications~ ~, A renewed analysis of the. data in the IMSD studies.in 1.998 by Dr. KSrblein and Prof. Hoffmann~" showed that there was a significant increase in the rate of childhood cancer within a radius of 5 kilometres. The increase was to be found 0nly when operational nuclear power plants were taken into account, not the decommissioned, plants,
- nor the research reactors. The increase was only found amongst infants under the age of 5 years old.
Methodology and findings, of the 2.007 KiKK Study The results of the KiKK .study.were published in December 2007 in the European Journal of Cancer~ and in the International Journal of Cancer~. The study covered all 16. large reactor locations where, the 20 nuclear power plants .in Germany were in operation during this period of time (period of study: 24 years, 1980 -2003). Since the Lingen and Emsland..locations are only two kitometres apart, they were combined, into one study region. In .the first part. of the study a total of 1592 under-fives with cancer were compared to a control group of 4735. children. The distance between, the.childrens homes and the .power plants was.precisely determined to within 25-meters.
The main. questions posed by. the study were: "Do. children under five years old more frequently develop cancer when living near a nuclear power plant?" and " is there a negative distance trend?"
(In other words: does the. risk increase the nearer one lives to the.plant?) The results showed not onlya ~60%.increas.e in the cancer rate and a 117%. increase in leukaemia in.infants within the 5 kilometre radius, but also a significant increase in the risk of cancer and Ieukaemia the closer one lived to the nuclear power plant.
In. the second part of the study, which covered a shorter period of time and a selection of.
diagnoses (leukaemia, lymphomas and tumours of the central nervous, system), it was tested
- whether other risk factors (confounders) could have had any appreciable effect on the. main result ofthe study -.the negative distance trend. This proved-not to be the case for any of the studied .risk factors. The proximity of residence to the nuclear power plant remains the only plausible influencing factor.
On the discussion on the "small number" of cases After the findings of the study were published in .December 200.7, the authors, frequently .
emphasised appeasingly, that the study basically "only" dealt with a small number of cases of cancer. 37. cases were observed where 17 would have been. expected statistically. This means that
- in a period of 24 years there was less than one additional le.ukaemia case a year. The 20 additional cases were only to be found within the 5 kilometre radius and were all cases of .leukaemia. The reciprocal distance rule. implicit in the study, however,, adds up to a total of 127 additional cases amongst infants for the whole region under study.
Moreover, it can be assumed that such effects do not .confine themselves to small children. Older children and adults could, also be affected. However, the rates of cancer development amongst these groups have not yet been the .subjectof a. comparable systematic study anywhere in the world.
it seems to me that the argument is significant that the KiKK study,, in. its methods and the questions it posed, was not set up to determine the exact number of additional cases of. cancer at all. One can. always find larger or smaller numbers of ill children according to the random selection of the size of the study area and using different distance rules. The latest. KiKK study has a
.methodological strength, however, in testing the distance. trend (which was also. the main question.
posed by the study). This overcame the disadvantage of classically-, dividing the area into. circular sections. But the KiKK study is inappropriate for determining the. absolute..number of cases. The authors reference to the small number of cases is obviously meant to soften the highly charged controversy .over the results of the study. In any case, the study proves that there is an increased risk that correlates to the proximity to nuclear installations. That the absolute number of additional cancer cases is not higher i.s in part due to the fact that the area around nuclear power plants is usually thinly populated°
Controversial interpretation of the KiKK study - was it only coincidence?
The authors of the study were. at first surprised by the results, they had arrived at. They .quickly pointed out that the raised levels of childhood cancer and ieukaemia in the vicinity of nuclear power plants could, not be explained by radioactive emissions. They.claimed that the doses of radioactivity calculated, to be in the Vicinity of nuclear power plants are below the average dose from .natural background radioactivity. Since this is not compatible.with current radiobiologicai thinking, they did not rule out the possibility of coincidence as an explanation.
The findings of the 2007 KiKK.study invalidate those of the previous "studies. by the Mainz Cancer Registry (IMSD 1992 and 1997). This should not really ~be a surprise, since KSrblein had already.
pointed these effects out many times, as had KSrblein and Hoffmann in their reanalysisof the
.IMSD study i.n 1998. For this .reason, KSrblei.n was strongly attacked by the Mainz .Cancer Registry
- and accused of "data dredging"~. However, the 2007 KiKK study completely confirms the IMSD reanalysis of 1998. The authors .belonging to the. Ma.inz Cancer Registry have also admitted in the meantime that their earlier studies had already shown an .increased cancer and leukaemia risk for infants living in close proximity to German nuclear power plants.
So what is the cause? "Coincidence" already has a. long. and sad tradition as an ultimate and
" helpless example, of interpretation in radiotogical causality research. Let me remind you .of the -
attempts made to explain the raised., levels of childhood leukaemia inthe area near the Kr0mmel power plant and Geesthacht nuclear research .centre. Previous ..inexplicable clusters were given as the explanation for another inexplicable cluster. Was it once again simply coincidence?Yet coincidence as an explanatory.modelwas clearly held to be improbable by the. external experts group, commissioned by the BfS to supervise the drafting, the execution and evaluation of the KiKK study~~. In referring to .coincidence, the Mai.nz authors are ignoring the current state of research.
Already in the summer of 2007, a comprehensive meta-analysis by Baker et al. on leukaemia in children living near nuclear power ptants~.caused a sensation. They examineddata contained in a total of 17 international studies carried out in Germany, Spain, France, Japan and North America during the. period between 1.984 and. 1999. EpidemioIogists at the University of South Carolina discovered an enhanced risk of between 14 and 2.1%. of developing leukaemia for children ~under nine years of age, depending on distance. All. ofthe people, examined under the age of 2.5 had an increased morbidity probability, of about7-10%, and the rates Of mortality were raised .by 2-18%.
Correlation. between the rate of morbidi,ty, emission measurements, calculation model for radiation exposure and the biological effects of radio.nuclides in Germany, .children that are living near nuclear power-plants develop cancer and ieukaemia more frequently that those living furtheraway. This has long been only a supposition, but has nowbeen clearly proven and is officially accepted~°.
If emissions have been correctl-y measured by monitoring the areas, surrounding nuclear installations, as has been claimed by both the NPP operators and the regulatory authorities, then
.either the currently accepted calculation models for determining radiation exposure of local residents are incorrect, or the biological effects of incorporated radionuclides have been badly underestimated, at least foryoung, children or embryos:
The results of the KiKK-study compel us to critically review not only the measurement of emissions by the operators but also the rules for calculating dose measurement and the risk models on which they are. based.. Any of these three steps, could help solve the contradiction between the allegedly low doses and .the severe effects. referred to by the authors.
A separate inquiry into.the boiling-water reactor design type is also necessary
.Boiling water reactors (BWR) have only one main cycle in their design. Pressure water reactors.
(PWR) have two separate main cycles, which means that BWRs have one less barrier holding back radioactive material from the surrounding areaThe weak point can .be found in. the machine room of the .NPP where highly radioactive hot steam is transported out of the reactor itself to the turbines.
in order to eliminate one individual location as the sole cause of the morbidity rate, the data in the study was assessed 1.6 times, each time excluding one location, in every case the exclusion did not change anything related to the main. result of the study - a negative distance, trend. It. was not tested, however, whether there was a difference in risk levels when comparing BWR or PWR design types.This question could beanswered easily enough using the existing study data.
,
Them is enough evidence to. show thatthe. BWRs in Germany (currently .B.runsbOttel, KrOmmel, Phillipsburg i, Isar. 1, Gundremmingen B + C; in the past W(3.rg.assen) have higher levels, of emissions. According. to the annual reports .of the .government, environmental, radioactivity and -
- mdi.ation exposure=~ of BWRs are appreciably higher than. those of PWRs, though within the currently accepted limits.
It is now time for us to act. The indications,over many years that there are increased levels of morbidity near to .NPPs have ,now been scientifically proven by the KiKK ,study..
N.oone can rule out the possibility of an increased risk for older children and adults living near NPPs, ASystematic investigation, of the type of the KiKK study .has still to be carried out.for these groups.
The previous mode of. measuring emissions and reporting them needs to be ..put to the test.
We c~n no longer rely o.n the information given by the NP.P operating company. There needs to be official monitoring without any gaps and measured, values .must be made public.
Previous assumptions about radiation risk, and the emission limits for radiation that are based on these, need to becritically re-examined and adapted to current international research findings..
In. addition, the data in the KiKK study should-be separately assessed according to. whether the location is a BWR or .PWR.
We should primarily think about the people affected - the precautionary principle is. long overdue, Further cases of cancer near to NP.Ps have to. be prevented. The only kind of reactor that does not present a cancer risk is a decommissioned reactor.
