Patrick S. Patrick Tucker. Excavations in and revealed an Ottawa bark burial with trade goods, a wooden cabin or shack, and an animal pen or compound.

A rich assemblage of Native and European-manufactured artifacts were recovered, including objects of trade silver. The site’s occupant s had a rich and varied diet. Faunal and floral remains consisted of domestic animals, corn, fish, reptiles, and molluscs. The site was part of the U. Ryan Jordan. Lance R Blyth. Mila Rechcigl. Contemporary with the American Civil War, the US-Dakota War, featured significant fighting, tactical brilliance, and strategic savvy set in the open plains of Minnesota and North Dakota.

Karl Jakob Skarstein’s “The War with the Sioux” tells the story of Norwegian immigrants, American soldiers, and Dakota and Lakota Indians as they fought to protect their families, communities, and way of life. Translated from Norwegian and supplemented with a preface and new introductions by Danielle Mead Skjelver, Richard Rothaus, Melissa Gjellstad, and Dakota Goodhouse, this work draws on the diaries, letters, and newspapers of Norwegian immigrants for a new perspective on the Northern Plains during these tumultuous years.

Skarstein’s work makes an important contribution to the growing body of scholarship on this conflict and offers an accessible and surprisingly intimate view of the conflict through the eyes of the Norwegian settlers in the region. All of the introductions are Open Access, and the full text, including the English translation by Melissa Gjellstad and Danielle Skjelver is available here.

The GISP2 cores and oxygen isotope analyses show that climatic fluctuations continued during the 10th millennium B. P Yu and Eicher Indications of these fluctuations were recorded when water levels rose early in the Holocene, only to fall in the second half of the millennium.

The GISP2 ice core record shows several fluctuations between warm and colder in the first few hundred years. The oxygen isotopes and carbon isotope analyses from southern Ontario support this pattern with a minor decline in temperature recorded for 9, yrs BP see Yu and Eicher Fig. While the fluctuations continue throughout the Holocene, temperatures cor- related with changes in oxygen isotopes do not dip as low as between 10, and yrs BP Yu and Eicher However, the dates for the pond also bracket a drying episode recorded in the oxidized sediments during that millennium.

At Bull Brook, water shield, naiads and twig-rush seeds, along with stonewort algae strengthen the rising water level hypothesis for the beginning of the Holocene.

Based on the pollen record, spruce, larch, and fir were replaced by white pine, birch, beech, and oaks in the Northeast Gaudreau ; Peteet et al. Plant macrofossils from cores and archaeological sites show that white pine, yellow and gray birch, and oak increased dramatically, and were quickly accompanied by a suite of temperate deciduous trees McWeeney ; Maenza-Gmelch Breaks in sedimentation and oxidation provide some of the clues that wetlands shrank and water levels dropped throughout the New England area Davis ; Jacobson et al.

Lower water levels have also been inferred from sedimentary hiatuses, sediment accumulation rates Newby nd , plus diatoms and sponge spicule identification from Pequot Cedar Swamp in southern New England McWeeney b. Oxidized, cemented, orange sediments, just below the water lily seeds AMS dated to 8, yrs BP at Pequot Cedar Swamp, suggest a period of extreme drying and possibly fire McWeeney Similar sediments are reported for Bull Brook McWeeney Transposing the dates to I sigma standard deviation, the drying period appears to occur sometime between 9, to 8, yrs BP In coastal Maine, Kellogg identified algal cysts suggesting shallow, stagnant water during the APine period at Ross Pond.

The abundant pine pollen may reflect colonization of the newly exposed, dried out shorelines by the white pine trees. In the White Mountains, white pine and hemlock grew beyond their modern tree line suggesting higher temperatures and a decrease in precipitation at 9, yrs BP Davis et al.

While modern investigations frequently revise older research, these dates support Deevey and Flint’s time for initiation of the Hypsithermal period at 9, yrs BP. Bryson et al. After 8, BP plants such as alder, sweet gale, elderberry, leatherleaf, rhododendron and brambles indicate shrub swamp conditions at Pequot Swamp McWeeney Gray birch and white pine trees provide a backdrop of pioneering species colonizing open spaces.

On the deeper, east side of the basin sedges, cattails, and twig-rush depict the initiation of marsh conditions. The shrub swamp transition also occurred at Bull Brook, Massachusetts, with scant evidence preserved from willow and leatherleaf, as well as gray birch McWeeney , an indicator of sterile, dry or wet soil Fernald The archaeological charcoal assemblages may not reflect the entire floral assemblage because of human selection and preservation issues.

However the charred remains provide an opportunity to see some of what was locally available during the millennium. Oak, aspen, and white pine trees provided some of the fuel wood at the Templeton site in Washington, Connecticut McWeeney White oak and white pine were abundant, as well, in the charcoal remains from an Early Archaic context at the Dill Farm site in southeastern Connecticut L.

McWeeney, personal research ; walnut and hazelnut shells were also identified Pfeiffer I. Red and white oak, ash, maple, hornbeam and white pine were identified from the Early Archaic Johnsen 3 site in upstate New York Funk ; McWeeney Based on the pollen, white pine has long been acknowledged as a component of the early Holocene forests; however, the charcoal from archaeological sites provides a more diverse picture of the deciduous trees also growing in southern New England at that time.

Dahl-Jensen el al. However, as in previous eras, the pattern was not static. According to Deevey and Flint , glaciers re-advanced in some parts of the globe around 7, BP, with cooling again between 5, and 5, yrs BP.

Occasional shifts to cold were interlaced with the warmer temperatures Grove ; higher summer temperatures returned between 5, and 5, yrs BP and again at 4, yrs BP. The GISP2 interpretations place the sharp decline in temperature ca.

However, within a few decades the warming increased around 7, BP and continued until another major cooling event appeared ca. The carbon isotope and oxygen isotope analyses show an earlier drop in temperature, ca. The pollen record provides additional evidence for fluctuating environments, with a predominant image of warming during the middle Holocene.

An increase in the amount of ragweed led Margaret Davis to interpret a decline in forest trees in the northeast around 8, years ago. She described a corollary to the onset of the prairie period reported for the mid-western states Davis The pollen spectra from Pequot Swamp recorded a decline innumerous deciduous trees North American Pollen data- base.

The increase in the ragweed pollen in Connecticut and an increase in oak in Vermont implied a drier climate around 7, yrs BP Davis et al. The presence of hemlock needles m.

However, Miller reported that several mesic pollen indicators remained in western New York, although oak and hickory decreased Miller This may record a very local condition since the Prairie period clearly expanded eastward at this time in the Midwest Cushing ; McAndrews For New England, the pollen spectra show a decrease in pollen deposi- tion rates, decline in pollen from forest trees, extension of tree ranges, and an increase in herbaceous plants.

Sediments and plant macrofossils document a drying period for the middle Holocene. A broadly distributed pattern shows an increase in charred organics in swamp cores from New England McWeeney , ; Sneddon ; Winkler , and as far away as Nova Scotia Green All of the cores recovered from Pequot Cedar Swamp contained a charred peat stratum 8 to 15 em thick. Lightning strikes on desiccated vegeta- tion or human accidents may have caused the widespread fires.

However, with the widely distributed geo- graphic pattern, climate appears to be the predominant cause. Following the fires, air circulation patterns apparently lofted the exposed soil up along the ridges outside of the basin. Dincauze described burial of the Neville component by aeolian sediments which continued to accumulate during the Stark occupation at the Neville site beginning before 7, and ending before 6, yrs BP.

The charred layers at Pequot Cedar Swamp and other New England sites hint at several episodic dry periods during the middle Holocene. Environmental data recovered from archaeological sites document what was available for human use during the middle Holocene. Regionally, mast trees such as oak, hickory, and chestnut played a significant role in the temperate forests during this interval. Watts concluded that the drier climate from before 8, yrs BP to about 5, yrs BP favored oak tree species.

This statement is reinforced by the archaeological assemblages. White pine and oak dominated the fuelwood selection at the Templeton site. Hickory became part of the oak and pine assemblage for the Middle Archaic period at Dill Farm Pfeiffer OAk, hornbeam, elm, alder, sour gum, and white pine were found in association with the hickory.

McWeeney, personal research documents the presence of hickory trees in southern New England region McWeeney thousands of years earlier than estimates based on the pollen Davis , Holly, ifit is flex opaca identified from the 2 Baker site, suggests a northern range extension for that tree during the middle Holocene, and provides another indication of warming.

To date, I have not identified chestnut charcoal from any Connecticut sites older than 2, yrs BP. This lack of evidence concurs with Davis’ pollen interpretation for a delayed migration of chestnut into New England. McWeeney, personal research.

The above mentioned archaeological examples clearly demonstrate contribution of identifying the charcoal for environmental reconstruction purposes. Detailed sediment analyses and AMS dates bracketing changes at every archaeological site would also make an enormous contribution to correlating dry episodes, wind activated intervals, and periods of erosion with settlement patterns. Not only did temperature and moisture regimes change, but also natural disasters such as fires, storms, volcanic eruptions Zielinski et al.

The rise in spruce pollen in New Hampshire around 2, years ago also suggests cooler temperatures Davis et al.

Plant macrofossils preserved in the Pequot Cedar Swamp cores McWeeney provide evidence for the appearance of numerous additional deciduous and conifer trees during the late Holocene. Charcoal from local fires preserved oak, beech, elm, maple, and hickory to provide a picture of the terrestrial environment during the last 5, years.

Atlantic white cedar began growing in the swamp during the late Holocene when water level fluctuations became less extreme McWeeney The plant remains from archaeological sites provide critical information for reconstructing the diversity of local prehistoric environments. The s excavation at the Boylston Street Fishweir Bailey and Barghoom documents native plant selection and use of their environment.

Based on the recovered stakes and wattle, 17 different taxa were used to construct the weir, portions of which date to 4, yrs BP Newby and Webb Red oak, beech, sassafras, and alder dominated the assemblage, with occasional use of sycamore, aspen, white oak, dogwood, bayberry, larch, and hemlock. The identifi- cation of larch and aspen presents a quandary, since modem aspen and larch.

Selection of the saplings appears to have been based on availability, not that a specific tree type was favored for stakes. Oak and pine continue as the dominant fuelwood choices into the Terminal Archaic period 3, to 3, yrs BP based on the charcoal identified from the Millbury site in Rhode Island McWeeney Ia. Largy identified charred seeds from the Millbury botanical assemblage that dramatically expand our knowledge of plants growing near the site: ragweed, goosefoot, grasses, purslane, blueberry, huckleberry, brambles, and hickory nuts.

Yet, the Terminal Archaic archaeological assemblage does not provide evidence of climatic cooling that was noted around 3, yrs BP by Deevey and Flint Significant evidence for a rarely recorded return to cold temperatures comes from clay deposits discovered along the Quinnipiac River, north of New Haven.

The presence of fir needles provides a strong indicator of cool, moist conditions in Connecticut at that time, possibly refining the date for Deevey and Flint’s “Little Ice Age” around yrs BP. Charcoal from two trees with a more southerly range has been identified from archaeological features from New Jersey, coastal New York and Connecticut.

Sourwood normally grows in Florida and Louisiana and in the Piedmont Zone as far north as Pennsylvania Fernald McWeeney, reports to CRM contractors e. Ceci infers that the presence of sourwood is due to native people bringing the wood to the site as an artifact or for medicinal purposes. Alternatively, it can be suggested that the presence of sourwood at three regional sites indicate it was growing there, and represents a northern range extension made possible during the global climatic warming period.

Black walnut, the second taxa found north of its normal range at the Morgan site, in Rocky Hill Lavin , came from a cultural feature with several deciduous woods such as sycamore and hickory McWeeney I b. A short distance north, up river, at the Burnham Shepard site Bendremer , similar wood charcoal was identified, including elm, hickory, hornbeam, ash, tupelo, cherry, and butternut.

No black walnut was identified. The modem range for black walnut in New England continues to find this taxa restricted to the coastal areas as far north as southern Massachusetts Little These black walnut specimens may be related to intentional planting during the Little Climatic Warming period. The new climatic conditions allowed their survival in the north; then human cultivation encouraged their continued growth. Significantly, the advent of maize horticulture along the floodplain of the Connecticut River, as evidenced from remains found at the Morgan site and Burnham Shepard did not eradicate the typical floodplain taxa as was found in Tennessee.

In that case, Cridlebaugh noted that a shift to upland taxa became necessary following intense levels of clearing the floodplain for maize agriculture. It may have been that maize agriculture was successful along the floodplain due to the warming climate and a decrease in spring and fall flooding that threaten crops today.

Stratigraphic analyses and sedimentation records remain to be explored to determine if this was the case in southern New England. Combining climate proxy data from the Greenland ice cores, oxygen isotope studies, pollen and plant macrofossils, as well as the sediments from lakes, ponds and swamps can make increasingly reliable inter- pretations. The botanical assemblages from cultural features at archaeological sites help refine the local environmental picture, and complement the other available data.

Evidence for several global climate changes has been recorded in Connecticut and elsewhere in southern New England, based on lake level changes, sediment anomalies, shifts in pollen accumulation rates, and range extensions for various plant macrofossils.

However, we need more details on the sedi- ments from archaeological sites as well as more AMS dating of individual plant remains to further refine the picture of the past.

The Connecticut sample includes dates. Connecticut dates are compared to radiocarbon chronologies from five other Northeastern states New Hampshire, Massachusetts, Pennsylvania, Maryland and West Virginia and southern Ontario. Connecticut and other New England states have bi-modal distributions of radiocarbon dates after BP.

Maize may not have been as significant to prehistoric subsistence in New England as in the Middle Atlantic region, and Late Woodland population increases were apparently less pronounced in New England.

These included only forty-five dates from archaeological sites and five geological dates. Only three dates were from Connecticut archaeological sites. The first Connecticut dates were two samples submitted by Suggs from the Manakaway site in Greenwich. David Thompson submitted the third Connecticut archaeological date from the Binette site, Naugatuck. In the three decades following Jordan’s early survey, radiocarbon dating became the most frequently utilized method for developing absolute chronologies for prehistoric sites and associated artifacts.

Table I assembles published and unpublished radiocarbon dates from Connecticut archaeological sites. These dates derive from cultural resource management surveys, doctoral studies, museum research files, academic institutions, and investigations by professional and avocational archaeologists. This list is intended as a research tool for cross-referencing radiocarbon samples, archaeological sites, artifact assemblages, and archaeological reports.

However, this paper poses the hypothesis that radiocarbon dates also reflect broader prehistoric cultural processes. Radiocarbon dating is commonly employed by archaeologists to evaluate prehistoric culture changes among material artifacts such as projectile points, ceramic types, burial practices, and subsistence patterns particularly the origins of agriculture. For example, all prehistoric peoples built hearths for warmth and cooking. More dated hearths might reflect more people during specific prehistoric periods.

Perhaps questionable radiocarbon dates from archaeological sites also provide chronological information for human activities in an environment over time. Charcoal might reflect periods of site occupations even if not directly associated with artifacts that archaeologists wish to date. Cultural factors probably influenced archaeological site formation, kinds of features constructed and preserved, and associated radiometric dates.

For example, throughout the Paleo-Indian and Archaic periods it is assumed that Native Americans hunted and gathered naturally occurring animal, plant and fish resources. Human populations were mobile in order to exploit highly pro- ductive seasonal resources, such as changes in animal ranges, fish spawning runs, and the differential ripening schedules of greens, roots, fruits, seeds and nut resources.

Many archaeological sites in Connecticut were reoccupied over thousands of years, suggesting favorable environmental conditions at particular locations.

Woodland period agriculture involved production of new food resources that might have led to lower seasonal mobility. Agriculture is also often associated with human population increases e. Sedentary agricultural lifestyles might have led to new types of deep storage features that were conducive to preservation of charcoal and other organic remains e. Greater numbers of features might have been associated with agricultural subsistence patterns such as food storage facilities, postholes from permanent structures, middens resulting from annual or pro- longed seasonal occupations, and perhaps palisades or other fortifications.

Therefore, adoption of agricul- tural subsistence strategies might be indicated by increasing numbers of radiocarbon dated features than during pre-agricultural times.

Many environmental factors also effect carbon preservation. Because charcoal and other organic matter physically decay over time, fewer and smaller carbon samples are usually available from Paleo- Indian and Archaic period sites than from more recent Woodland period sites.

Geological processes have destroyed archaeological sites throughout the Holocene period of human occupations. Sea levels have risen and have inundated coastal sites. Rivers and streams have eroded valleys and terraces. Geomorphic proc- esses have probably destroyed a greater number of older archaeological sites, and associated charcoal samples, than recent sites. Carbon physics and chemistry also influence radiocarbon dates as valid chronological indicators of human occupations at archaeological sites.

Bristlecone pine calibrations Suess ; Stuiver et al. Recent data from Greenland ice cores and uranium-thorium dates from corals and from other sources have extended the cali- bration range to include the Paleo-Indian period e. By Paleo-Indian times, the magnitude of error for radiocarbon dates is more than 2, years earlier than actual calendric dates. Radiocarbon dates are usually reported as BP dates radiocarbon years before present, and are converted to calen- dric dates BC or AD following calibration.

Shells, bone and short-lived plant materials have often provided inaccurate radiometric dates. Accelerator mass spectrometry AMS dating techniques have greatly relieved problems of small carbon samples and differences among dated materials.

C 13 isotope corrections can also be applied to plant samples with a C4 pathways, including maize and other cultigens. Radiometric dates also reflect the research designs of individual archaeologists who selectively excavate sites, submit samples, and publish results from radiometric dating to support specific research questions. Sets of radiocarbon dates might reflect biases among researchers rather than unbiased samples of archaeological sites or features.

Many of these factors were considered when assembling radiocarbon data from Connecticut. Inter- pretations of the Connecticut radiometric chronology were aided by comparisons with other radiocarbon sequences from Northeastern North America. Until about , archaeological sites were recorded by Smithsonian inventory numbers identifying the state number e. Since approximately , the Connecticut Historical Commission and the Office of the State Archaeologist have inventoried archaeological sites by an alphabetical town number and site series number e.

The Connecticut radiometric database derives from combined efforts of numerous archaeologists and research institutions. The Connecticut database presently includes radiocarbon dates from archaeological sites Table I.

Radiocarbon dates are listed from older to more recent dates. Information was collected from published sources, unpublished archaeological survey reports on file with the Connecticut Historical Commission, Ph. C C 12 corrections were selected for this list when this information was available. Laboratory numbers are reported on Table I. Connecticut site inventory numbers have been compiled for named sites from computerized site files of the Connecticut Historical Commission.

Radiocarbon dates are also presented for twenty-two sites that either have not yet received site numbers or for which site forms have not yet been filed with the Connecticut Historical Commission.

Towns and physiographic regions associated with archaeological sites have also been reported on Table I. Archaeological information presented on Table I includes site names, features or site proveniences of dated samples, and the material submitted for dating e.

Projectile point types, ceramic types, cultigens, and other important cultural materials associated with radiocarbon dates are included on Table I. Typological information for artifacts often varies between archaeological reports. The expected prehistoric cultural periods of artifacts are also listed. Published and unpublished references for radiocarbon dates are presented below. Table 2 summarizes the radiocarbon database from Connecticut towns and physiographic regions.

Table 2 describes the numbers of archaeological sites with radiocarbon dates, the numbers of individual dates from towns, and the range of dates from towns. Only 34 percent of Connecticut towns 57 towns have dated prehistoric archaeological sites. Most towns have few dates that only encompass segments of the prehistoric chronological sequence. Ledyard has the most dates 41 dates largely resulting from cultural resource surveys sponsored by the Mashantucket Pequot Tribal Nation.

The Northwest Highlands encompass an area of The highest point in Connecticut is feet elevation on Mount Frissel at the northwest comer of the state. The average elevation for all towns in the Northwest Highlands is feet above sea level O’Brien Mountains and rolling plateaus drain into the narrow valleys, including the Shepaug River tributary to the Housatonic River, and the Farmington River that drains into the Connecticut River.

An aggressive program of archaeological excavations and radiocarbon dating began in western Connecticut during by the Shepaug Valley Archaeological Society Swigart Swigart reported 10 radiocarbon dates from the Northwest Highlands and II dates from towns in the adjacent Western Uplands. The Institute has continued to support archaeological research projects. The present sample of radiocarbon dates from the Northwest Highlands includes 32 dates from 20 archaeological sites among six towns Table 2.

This is the smallest sample of radiocarbon dates from any region of Connecticut. This date derived from an organic sample and might be of geological rather than human origin. Western Uplands The Western Uplands is a region of rolling hills and valleys.

The uplands are also head- waters to several smaller rivers that flow south into Long Island Sound including the Norwalk, Saugatuck, Mill and Pequonnock Rivers. The Western Uplands includes The average elevation of towns in the Western Uplands is feet above sea level O’Brien The Western Uplands presently have a sample of 61 radiocarbon dates from 26 sites among II towns.

McWeeney’s three earliest carbon samples between 10, to BP probably relate to Paleo-Indian occupations at the Templeton site. All of these Paleo- Indian charcoal samples were identified as oak or hickory wood, suggesting early Holocene expansion of temperate hardwoods into the uplands of Connecticut by Paleo-Indian times McWeeney A total of 36 radiocarbon dates were procured from sites along the Connecticut sections of the transmission corridor, including 14 dates from seven Western Upland sites, 21 dates from three sites in the Western Coastal Slope region, and one date from the Northwest Highlands.

Other cultural resource management surveys have also contributed substantial numbers of radiocarbon dates from the Western Uplands.

Seven dates are available from the Newtown Sewer site in Newtown Jones et al. David Thompson , , personal communication, has maintained a tradition of Archaeological Society of Connecticut field research in the Western Uplands, reporting six dates from the region. Western Coastal Slope Long Island Sound provides rich environments of marine fisheries, abundant coastal shellfish, and estuary habitats with diverse plant and fish nursery communities.

Sea levels have risen throughout the Holocene period of human occupations. The shoreline of Long Island Sound was approximately 40 m below modern sea levels at approximately 12, BP, 25 m lower between approximately and BP,5 m lower at BP, and approximately 2 m lower at BP Gayes and Bokuniewicz Rising seas have destroyed older archaeological sites along former coastlines, and have eroded headlands and inundated river valleys that may have been important locations for human occupations.

A total of 60 radi- ocarbon dates has been reported from 19 archaeological sites within five towns Table 2.

Wiegand has accumulated 34 pub- lished and unpublished radiocarbon dates from nine sites in the region Wiegand , , and personal communication. In addition, excavations conducted along the Iroquois Gas Transmission System included 21 radiocarbon dates from three sites in Milford Millis et al.

Central Valley The Central Valley formed from faulting and subsidence along its eastern border and sedimentary filling of the valley floor Bell Metacomet Ridge rises along the middle of the Central Valley as a result of volcanic intrusions into sedimentary brownstone formations.

Following glaciation, the falls of the Connecticut River at Windsor Locks was a significant ecological barrier to spawning fish moving up the Connecticut River. The Central Valley encompasses an area of 1, Towns of the Central Valley average feet elevation O’Brien The prehistoric chronology of the Central Valley contains 66 dates from 36 archaeological sites in sixteen towns Table 2. Kevin McBride initiated intensive radiocarbon dating for his doctoral research within the Connecticut River valley.

McBride’s doctoral dissertation and preparatory publications reported 15 radio- carbon dates from the Central Valley, 13 dates from the Eastern Uplands, and 19 dates from the Eastern Coastal Slope regions McBride , ; McBride and Dewar In , Peter Pagoulatos completed a study of Terminal Archaic settlements, reporting nine new radiocarbon dates within the Connecticut River valley.

In , Jonathan Lizee a reanalyzed prehistoric ceramics associated with the Windsor Ceramic Tradition from dated archaeological sites both within and outside the Connecticut River drainage also see Lavin , These studies greatly expanded information about the timespans of particular artifact types and subsistence resources within Connecticut.

Many other archaeological projects have been conducted in the Central Valley. Yale University conducted excavations at the Lewis-Walpole site, Farmington, between and , and Starbuck published 2 radiocarbon dates. Feder a, b, , in press, n. The region was greatly affected by Pleistocene glaciation, and many modern landforms were formed from moraines and deltatic deposits Lewis and Stone Similar to the Western Coastal Slope, rising sea levels have inundated early Holocene shorelines and associated archaeological sites.

The Eastern Coastal Slope contains radiocarbon dates from 44 archaeological sites within eight towns. John Pfeiffer reported 22 dates from the region in publications leading toward his doctoral dissertation at the State University of New York at Albany about Late Archaic and Terminal Archaic cultures of the lowest Connecticut River valley Pfeiffer , ; Pfeiffer and Stuckenrath MPMRC project files include 29 unpublished dates from seven sites. Many other archaeological surveys have been conducted along the Eastern Coastal Slope.

Amateur archaeologists have investigated possible Medieval Celtic settlements at Gungywarnp, Groton, and have received radiocarbon dates of , , and BP preceding, contemporaneous with, and following the supposed Medieval period of early European colonization Barron , Whittall and Barron Eastern Uplands The Eastern Uplands encompasses an area of 1, square miles within 41 towns Figure 1.

The region is primarily composed of rolling metamorphic formations that form headwaters to the Salmon and Moodus Rivers draining to the Connecticut River, the Yantic and Shetucket Rivers that form the Thames River at Norwich, the Quinebaug River that joins the Shetucket River above Norwich, and the Pawcatuck River that is the boundary with Rhode Island Bell The average elevation of towns in the Eastern Uplands is feet above sea level O’Brien A total of 34 new radiocarbon dates was reported from this project, including dates for Neville-Stark projectile points from the Bolton Spring site ranging between BP and 10, BP.

Regions of Connecticut differ in the number of radiocarbon dates and sites investigated by archae- ologists Table 2. The Eastern Coastal Slope contains twice the number of dated sites and more than three times as many radiocarbon dates as the Northwest Highlands.

Varying sample sizes of radiocarbon dates might influence assessments of regional cultural chronologies. Differing histories of archaeological research within various regions might have introduced biases into the radiocarbon database. Lizee a and Lavin , focused on Woodland sites that contained ceramics. Bendremer ; also George focused on Late Woodland agricultural sites.

Many CRM highway surveys have been conducted along level river terraces that may not have existed during the Early Holocene. Do selective research designs inflate numbers of radiocarbon dates from particular periods? Table 3 summarizes temporal distributions of radiocarbon dates from different physiographic regions in Connecticut.

Dates have been combined into standardized year intervals based upon uncalibrated mean laboratory dates. The primary assumption of this study is that radiocarbon dates represent relatively unbiased samples.

While archaeologists may differentially select artifacts or feature types for dating, we believe that archaeologists are incapable of predicting specific ages of radiocarbon samples. Archaeologists often reject radiocarbon dates that do not meet preconceived chronological parameters for artifact use or site occupations.

Rejected dates are also included in this database. Rejected dates may provide previously unsuspected evidence for cultural chronologies. Figure 2 presents frequency curves numbers of dates per year intervals for total Connecticut radiocarbon dates and chronologies for six physiographic regions.

Several patterns are notable. If archaeological research designs have biased the radiocarbon database, then separate regions should have differing radiocarbon chronologies based on research activities of individual archaeologists. These modes are not expressed in the Northwest Highlands possibly because of the small number of dates from this region, but perhaps also because of different cultural-ecological processes in mountainous habitats.

Sea level rise, and consequent destruction of early archaeological sites, may have been more severe along the Western Coastal Slope than along the Eastern Coastal Slope. Late Archaic dates are less common in the west than the east. No amount of sampling bias can account for the consistent lack of radi- ocarbon dates between BP and BP across all physiographic regions of Connecticut.

Connecticut radiocarbon dates dates per year interval in geographic region. Geographic patterning of these radiocarbon date modes is beyond its likelihood of archaeological sampling bias, and probably reflects undetermined cultural processes in Connecticut. One tempting hypothesis is that regional modes reflect shifting population centers, perhaps associated with ethnic migrations e.

However, this question is beyond the scope of this paper. Connecticut radiocarbon dates should contribute to general understanding of prehistoric cultural changes. The Connecticut radiocarbon chronology can be appreciated from comparisons with other studies of prehistoric chronology and culture change in Northeastern North America. Ritchie’s prehistoric cultural chronology for New York was developed from relatively large numbers of radiocarbon dates during the early decades of radiocarbon dating in archaeology.

The New York chronology has provided structure for New England archaeology until the present time e. Ritchie’s cultural sequence included a then poorly dated Paleo-Indian Stage ca. Each cultural stage was associated with artifacts and other material traits that presumably conferred progressive adaptive advantages, and possibly effected prehistoric human populations over time. The Archaic Stage was first named by Ritchie , based upon excavations at Lamoka Lake and other sites, to signify pre-ceramic cultures subsisting by hunting, gathering wild plants and fishing.

Ritchie initially defined two projectile point traditions within the Archaic Stage. Initial lack of radiocarbon dated sites between 10, BP and BP led Ritchie and Funk ; after Fitting to speculate whether an Early Archaic Sub-Stage was a period of population abandonment in the Northeast, associated with low resource productivity of early post-glacial boreal conifer forests.

Pollen and macro-botanical studies have subsequently demonstrated that mixed hardwood forests had expanded into the region at much earlier times e. The Early Archaic 10, – BP was established from radiocarbon dates at Staten Island sites that contained Kirk, Palmer, and bifurcate-base points analogous to point types in the Southeastern United States Ritchie and Funk The Maritime Archaic has not been identified in Connecticut.

The Transitional Stage or Terminal Archaic was associated with an expanded material inventory toward the eventual manufacture of pottery Ritchie Transitional Stage artifacts included steatite vessels, early Vinette I pottery, and Susquehanna, Frost Island and Orient projectile points.

Burial cere- monialism was also a recognized as trait of the Transitional Stage in New England Dincauze Radi- ocarbon dates demonstrated broad chronological overlaps among Archaic projectile point traditions and other artifacts in New England Hoffman The Late Woodland showed increasing influences from maize agriculture and regional diversification of ceramic types in New York after BP Ritchie and Funk Late Woodland projectile points included Levanna and Madison triangular types.

Many radiocarbon samples have been submitted by archaeologists during the decades following the publications of Ritchie’s New York prehistoric chronology, and Jordan’s early survey of New England radiocarbon dates.

As radiocarbon databases grew, lists of dates were published from many New England and Middle Atlantic States. Studies include Hoffman’s list of dates from Massachusetts, Gengras’ list of dates from New Hampshire, Herbstritt’s dates from Pennsylvania, Trader’s list of dates from West Virginia, and Boyce and Frye’s dates from Maryland.

A list of dates is available from southern Ontario covering the Middle and Late Woodland periods Smith In addition, Hoffman has recently published a list of dates for steatite and early ceramics from New England.

Most of these studies reported uncalibrated radiocarbon dates radiocarbon years before present or BP. Date sequences are therefore uncalibrated in following discussions and in Table I. As noted above, radiocarbon dates are valuable for studying changes of prehistoric material culture.

Assumptions of randomness might be invalid, but this question should be examined through a review of available data. Table 4 summarizes the numbers of uncorrected radiocarbon dates within year intervals from individual states. Simple frequency distribution curves number of dates per year interval have been compiled for each state and regional radiocarbon study.

Therefore, it is not possible to compare prehistoric cultural chronologies in quite the same ways between all areas of Northeastern North America from the published studies of radiocarbon chronologies. Differences in approaches between different studies are often illustrative of varying research designs and problems of radiocarbon dating, in general. M cc ;:! N S; o; r-. The Maryland sample was relatively small with only dates.

The earliest date at the time of the study was BP. Rising sea levels flooded many Chesapeake Bay archaeological sites, perhaps accounting for few Archaic dates in the Maryland sample. A large increase of dates occurred after BP, marking the beginning of the Late Woodland.

Subsequent archaeological studies have demonstrated that maize appeared at many sites along the western shore of Chesapeake Bay at approximately BP Reeve Maryland Dates after Boyce and Frye The Maryland sample reflects one problem of radiocarbon chronologies. During the s, the federal government and Maryland Coastal Zone Administration sponsored Chesapeake Bay coastal archae- ological surveys e.

Oyster shells from many prehistoric shell middens were directly dated. Figure 3 suggests differences between shell and wood charcoal dates.

Shell dates were consistently older than wood charcoal dates, possibly biasing chronological patterns with numerous spuri- ous dates in this small sample.

Non-shell samples magnify the increase of radiocarbon dates during the Late Woodland period Figure 3. Figure 4 is a West Virginia sample of dates Trader Albans site. Bifurcate Base points ranged between and BP. Shifts to maize agriculture occurred earlier in the Ohio River valley than in the Chesapeake Bay area and New England. Figure 5 presents a large sample of dates from Pennsylvania Herbstritt Herbstritt reported cultural periods rather than specific artifact types associated with radiocarbon dates.

Herbstritt’s cultural periods approached normal uni-modal distributions for date frequencies. The Paleo-Indian period ended by approximately BP. The Early Archaic might have extended to BP. Early Woodland to Late Woodland periods tended to overlap in time. The overall Pennsylvania pattern suggested punctuated increases and then stabil- ity for the numbers of dates over time from the Paleo-Indian through Middle Archaic periods and again during the Late-Terminal Archaic through Middle Woodland periods.

West Virginia dates after Trader and selected point types. Woodland dates was evident after BP. Similar to date sequences to the south of Pennsylvania, the dramatic increase of Late Woodland dates might reflect the adoption of maize agriculture, marking both sedentary villages and population increases.

Recently, Smith focused attention on the Middle to Late Woodland transition to maize agri- culture in southern Ontario. Southern Ontario cultural phases were examined from radiocarbon dates between and BP Figure 6. This is currently the earliest verified date for maize macro-botanical rather than pollen evidence in Eastern North America outside of the Mississippi-Ohio River drainage e.

Smith suggests that early maize BP might have been traded into the southern Ontario, or was part ofa mixed hunting-gather- ing-fishing-horticultural subsistence economy. Relatively low frequencies of Middle Woodland dated sites indicate population stability among southern Ontario hunter-gatherers until after BP, when a large increase of radiocarbon dates indicated expansion of agricultural villages among Early Ontario Iroquoians.

The dramatic increase of Early Ontario lroquoian dates after BP was consistent with the chronology for agriculture from the Middle Atlantic region to the south. A comparative list of radiocarbon dates from northern New England has recently been published for New Hampshire Gengras The New Hampshire sample included dates from 38 sites Figure 7.

This study did not report associated artifacts or cultigens, but instead listed dated sites by river systems. The total New Hampshire sample demonstrated relative continuity of radiocarbon dates from the Paleo- Indian period at the Whipple site through the Middle Archaic periods.

A smaller Late Woodland mode occurred at BP. Pennsylvania dates after Herbstritt and cultural periods. Southern Ontario dates after Smith and cultural phases.

New Hampshire dates after Gengras and geographic regions.
