On the Age of Serpent Mound: A Reply to Romain and Colleagues

Radiocarbon dates reported by Romain and colleagues (2017) suggesting that Serpent Mound (33AD1) is an Adena effigy mound are problematic because they cannot be linked reliably to cultural activities associated with the original construction of the effigy mound. Additional arguments offered by Romain and colleagues (2017) in support of an Early Woodland age for Serpent Mound also are unconvincing. A Late Prehistoric age for Serpent Mound is supported by the radiocarbon dates reported previously, new radiocarbon dates, the relative abundance of serpent imagery in the Fort Ancient culture and the contemporaneous Mississippian Tradition, the virtual absence of serpent imagery in the Adena culture, and the fact that, whereas effigy-mound building is otherwise unknown in the Early Woodland period, it is well documented, if rare, for the Fort Ancient culture and in the not-so-terribly-far-away upper Midwest it is so common that it defines the broadly contemporaneous Effigy Mound culture.     

Debating the Age of Serpent Mound: A Reply to Romain and Herrmann’s Rejoinder to Lepper Concerning Serpent Mound

The debate over the age of Serpent Mound (33AD01) is important because without a cultural context it is impossible to make meaningful statements about what this monumental effigy mound might have meant to its builders. In this response to Romain and Herrmann’s rejoinder, we clarify the provenience of the samples, which yielded the radiocarbon dates that contribute to our argument for a post–Late Woodland age for the effigy. In addition, we extend our critique of Romain and colleagues’ arguments to include the results of an independent study of soil cores extracted from the Serpent and surrounding landscape, which fails to corroborate Romain and colleagues’ assertion that a buried A horizon underlies the mound. Finally, we suggest that the construction of Serpent Mound may be historically linked to droughts in the Mississippi Valley that began at around AD 1100, which resulted in an influx of Mississippian refugees into the region.     

Serpent Mound in its Woodland Period Context: Second Rejoinder to Lepper

The Serpent Mound in Adams County, Ohio, is probably the most widely recognized effigy mound in the world. Opinions differ, however, as to who built the effigy and when. Currently there are two conflicting positions. According to Lepper and colleagues (this volume and elsewhere) the effigy was built by people of the Fort Ancient culture circa AD 1070. According to the present author and colleagues, recently obtained radiocarbon dates and other data indicate that Serpent Mound was built much earlier, by people of the Adena culture, circa 320 BC.

In this article, evidence is presented that corroborates the earlier published radiocarbon dates suggestive of an Adena-era construction. This evidence includes a review of findings that real serpents were sometimes buried with Adena and Hopewell people and consideration of a relational complex reaching back to the Early Woodland—wherein the Great Serpent of Native American legend is associated with the journey of the deceased person’s soul, the star constellation Scorpius, and the Lowerworld. Together, these data provide an Early Woodland cultural and interpretive context for Serpent Mound and further corroborate the Adena-era radiocarbon dates for its construction.     

Radiocarbon Dates Reveal Serpent Mound Is More than Two Thousand Years Old

Recent radiocarbon dating (Herrmann et al. 2014) found that Serpent Mound was likely built during the Early Woodland period—around 320 BC. Herrmann et al. (2014) also suggested that the effigy was repaired or restored during Fort Ancient times, thereby accounting for the late prehistoric radiocarbon-dated samples recovered by Fletcher et al. (1996). The present article presents new data in support of the Early Woodland construction date. These data include lidar analyses, electrical resistivity ground imaging (ERGI) studies, and iconographic assessments.     

Recovering the Forgotten Woodland Mound Excavations at Garden Patch (8DI4)

Forty-five years ago Timothy Thompson excavated at two of the six mounds at the Garden Patch site but results were never reported. We assembled data from Thompson's work and enhanced them with new test pits at Mound IV and re-excavation of a Mound V trench. Mound IV is a natural sand ridge where a village was established early, by the second century A.D. Mound V began as a naturally elevated platform for at least one burial and associated structure during the fourth century A.D. and was then covered by lenses of shell and sand. The construction sequence of Mound V resembles other mounds in the region. These results help illuminate the functions and depositional histories of mounds within Woodland multi-mound centers of the coastal plain while also demonstrating an effective approach to balancing stewardship and new excavations.     

The Chinese Upper Paleolithic: Geography, Chronology, and Techno-typology

This article reviews the archaeology and chronology of the Chinese Upper Paleolithic and the human fossils attributed to this period. The onset of the Upper Paleolithic in China dates to ca. 35,000–30,000 years ago and is marked by the appearance of a few body decorations and well-shaped bone tools that were added to stone tool assemblages, including core-and-flake tools in North China and cobble tools in South China. The proliferation of blade assemblages in northwest China is interpreted as the cultural impact or the physical presence of bearers of blade industries from western Eurasia. The ensuing appearance of microblade assemblages in North China by 23,000–22,000 years ago reflects the use of local siliceous crystalline nodules by a population that recognized the advantages of this raw material. At that time in South China, prehistoric artisans continued to shape their stone objects from the available flat river cobbles. During the later part of the Chinese Upper Paleolithic (ca. 21,000–10,000 BP), foragers also made bone tools, antler objects, pottery, and shell tools, which laid the technological foundations for the early Neolithic period. One difficulty in this research is that human fossils are rare. Few are well dated and morphological, cultural, and biological interpretations are hotly debated. Our review attempts to facilitate the understanding of a poorly known period in Chinese archaeology and its place in human cultural evolution.     

Late quaternary alluviation and soil formation in the southern Argolid: its history,causes and archaeological implications

In the context of an archaeological survey of the southern Argolid, Greece, studies have been carried out to elucidate the evolution of the landscape since its earliest known human occupation about 50,000 years ago. One of these studies was a detailed geological mapping of the late Quaternary alluvium and soils in the area. Dated by means of thorium-uranium disequilibria, archaeological finds, and historical information, seven periods of alluviation were identified, each of short duration relative to long intervening periods of stability and soil formation. The three earliest alluvial phases, falling before and during the last glacial interval, range from about 330,000 to 32,000 years in age. No alluviation accompanied the last glacial maximum around 20,000 years ago. In fact, a stable landscape persisted until about 4500 years ago, when debris flows and widespread aggradation in the valleys resulted from major slope destabilization and soil erosion, probably as a result of extensive land clearance in the Early Bronze Age. A subsequent stable period lasted through the many upheavals of the later Bronze Age, the Dark Ages, and the early historical period. It came to an end with a brief phase of alluviation between about 300 and 50 BC. Stability returned through the late Roman period, notwithstanding considerable expansion of the settled area. Another period of destabilization, this one marked by debris flows and hence major soil erosion, is poorly fixed in time, but probably coincides with expanded maquis clearance accompanying the resettlement of the area around AD 1000. Subsequent events of soil erosion and aggradation vary in nature and timing from one drainage to the next and, in some areas, continue today.Nature and chronology of the soil forming and alluviation events show that simple correlations with climatic events do not suffice to explain them. For the latter ones, past about 2500 BC, human activity seems to be the dominant cause, but once again the relation between cause and effect is not straightforward. Land clearing, or neglect of soil conservation efforts during economic downturns, appear to have a more devastating effect upon the landscape than do intensive land use or total land abandonment.     

THE 1974–75 EXCAVATIONS AT MOUND BOTTOM,A PALISADED MISSISSIPPIAN CENTER IN CHEATHAM COUNTY,TENNESSEE

Abstract

Mound Bottom (40CH8) is a large complex of 14 prehistoric mounds located in a horseshoe-shaped bend of the Harpeth River, a tributary of the Cumberland, in Cheatham County, Tennessee. It, together with another mound group 3 km to the south known as the Pack site (40CH1), received sporadic archaeological attention during the first half of the twentieth century, but it was not until 1974 that systematic work was carried out at either mound center. Over portions of that and the following year, Mound Bottom was mapped in detail and excavations were carried out to document the range in variability of mound construction and community structure. Six mounds were tested and 19 houses were partially or totally excavated. House types included both single-set-post structures and wall-trench structures. Calibrated radiocarbon dates from Mound Bottom span about a 600-year period from the eighth through the fourteenth centuries.     

Settlement and social change in central Europe, 3500–1500 BC

The chronology of the period is briefly considered in the light of the dendrochronological results which have appeared in recent years. Patterns of settlement history in different parts of the area are then examined, and it is suggested that in some of them the late fourth millennium was a period of population decline which was not reversed until the Early Bronze Age, 1000 years later. Detailed information about specific local occupation patterns is provided by recent work on the circum-Alpine lake villages. Changes in cultural patterns during the period, especially the appearance of the Corded Ware, are discussed and explanations of them reviewed. It is argued that changing patterns of gender relations were a major feature of the period, linked to processes which eventually led to the development of small-scale chiefdoms. The development of copper and bronze metallurgy and its connection to these processes are discussed.     

Evaluating the Reliability of Fluoride Dating at Two Prehistoric Mound Sites in Mississippi

Abstract

Ion-selective electrode fluoride dating is used to address chronological problems at two mound sites located in Mississippi. At the Mississippian period (A.D. 900–1520) Lyon's Bluff site, 220K520, the fluoride content of deer and human bone is compared with radiocarbon dates and stratigraphic levels to evaluate the reliability of the fluoride dating method for understanding relative burial chronology. At a second site, Pocahontas Mound A (22HI500), fluoride content of deer bone is used to corroborate radiocarbon dates and to establish the proper chronology of levels associated with two distinct occupations (Archaic and Coles Creek/Plaquemine) identified in a large midden area. Fluoride analysis also is used to date a second midden area at this site. For Lyon's Bluff; fluoride dates did not correspond with accelerator mass spectrometry (AMS)-dated burials and midden strata. In contrast, fluoride dating proved very useful in determining chronological placement of midden levels and dating other areas at Pocahontas Mound A. Sample age, site location, soil, and bone preservation are considered as possible causes for the negative results at Lyon's Bluff.     

Paleodietary analysis of the sacrificial victims from the Feathered Serpent Pyramid,Teotihuacan

The consumption of different types and quantities of food frequently serves as a practice that expresses and reinforces social distinctions among individuals within complex societies. This study explores the dietary behavior of probable sacrificial victims interred within the offering complex underlying the Feathered Serpent Pyramid as a line of evidence concerning the identities and life experiences of individuals selected for inclusion within one of Teotihuacan’s public monuments. Stable carbon, nitrogen, and oxygen isotope values from rib samples of 12 individuals within the Feathered Serpent Pyramid complex were compared with those of 14 individuals interred in residential contexts within the city. Results provide new information concerning daily subsistence at Classic period Teotihuacan (ca. A.D. 200–600) and highlight the dietary distinctiveness of individuals interred within the Feathered Serpent Pyramid as compared to the general residential population of the site, particularly in terms of the carbon isotope composition of protein sources consumed by a number of the sacrificial victims. Oxygen isotope analysis suggests that most individuals from the Feathered Serpent Pyramid resided within the local Teotihuacan area during the years immediately prior to their deaths, indicating that the unique dietary pattern seen in stable carbon isotope values cannot be attributed to nonlocal residence prior to sacrifice. Rather, these dietary differences may suggest that the group of individuals selected for interment within the Feathered Serpent Pyramid offering complex maintained a distinctive social or economic identity as compared to the rest of the Teotihuacan population during their lives.     

Tree-ring based temperature reconstruction for the west Qinling Mountains (China): linkages to the High Asia,solar activity and Pacific-Atlantic Ocean

We developed a Faxon fir (Abies faxoniana) tree-ring width chronology at the timberline in the western Qinling Mountains, China. Herein February–July mean temperature was reconstructed for Zhouqu in the western Qinling Mountains back to AD 1650 based on the standard chronology. The climate/tree-growth model accounts for 43.5% of the instrumental temperature variance during the period 1972–2006. Spatial correlation analyses with the gridded temperature data shows that the temperature reconstruction captures regional climatic variations over central and southeast China, and strong teleconnections with the nearby High Asia. There is a good agreement with cold and warm periods previously estimated from tree-rings in Nepal, India and southwest China. The temperature re-construction indicates that there was pronounced cooling in Zhouqu during the Maunder Minimum (late 1600s to early 1700s). The cold period (1813–1827) of the temperature reconstruction coincide with the volcanic eruptions. Significant spectral peaks are found at 56.9, 22.3, 11.4, 2.9, 2.8, 2.6, 2.2 and 2.0 years. The spatial correlation patterns between our temperature reconstruction and SSTs of the Atlantic and Pacific Oceans suggest a connection between regional temperature variations and the atmospheric circulations. It is thus revealed that the chronology has enough potential to reconstruct the climatic variability further into the past.     

Post-glacial environmental change and hunting-gathering societies of the southern Prairie Peninsula

Evidence from several disciplines supports the proposition that following the Wisconsinan and an initial but brief moist phase of the Holocene, there was a gradual drying trend in the mid-continent Prairie Peninsula that peaked about 7000 years ago, a pattern that was not reversed until about 4000 years ago. Except for minor perturbations, conditions during the past four millennia have essentially been similar to those of the present. Studies in palynology and geomorphology have shown that the climatic regimes of the early/mid Post-glacial had a marked influence on both the biota and landscape erosional patterns, especially along the margins of the Prairie Peninsula. Measurable changes in the landscape and attendant biota show a time-transgressive pattern of drought related phenomena recorded palaeo-ecologically from west to east.Few studies of archaeological sites in the Prairie Peninsula have examined the evidence in and around the sites themselves for data reflecting local environmental dynamics. In fact, earlier models proposed for explaining the evolution of food-procuring systems in eastern North America virtually ignored potential changes in the natural environment. This paper examines data from two archaeological sites along the prairie-forest border in Missouri that contain long cultural sequences. Evidence is presented that pronounced changes in the natural environment occurred and that these biophysical variables are indeed critical for understanding the evolution of food-procuring societies in the American Midwest.     

3400 years of agricultural engineering in Mesoamerica: lama-bordos of the Mixteca Alta,Oaxaca, Mexico

The origins of early Mesoamerican agricultural techniques are not well established. Our charcoal-derived radiocarbon chronology dates cross-valley check dams, or lama-bordos, buried by up to 11.5 m of sediment in arroyos near Coixtlahuaca, Oaxaca, Mexico. Now it is clear that people in highland Mexico built lama-bordos at least 3400–3500 years ago, several hundred years earlier than previously dated engineering systems in Mesoamerica. Lama-bordo systems evolved as intensively and extensively managed landscapes coeval with climate shifting to more arid conditions. They provide clear examples of human-produced stratigraphy and artificial landscapes (stair-stepped valleys). More importantly, these lama-bordo systems signal a major cultural tipping point toward sedentary agricultural life and solidify our understanding of the Neolithic transition in Mesoamerica.     

Terra incognita: terrestrial LiDAR documentation of Mound A at Kolomoki (9ER1)

ABSTRACT

The manifest representation of space and place is essential to good archaeology. Our ability to document and relate these concepts, projected into the past and reflected in the present, has increased tremendously with the expansion and availability of technology. We present recent efforts to further document a well-known place in the cultural landscape: the Kolomoki site in southwestern Georgia, occupied primarily during the Middle and Late Woodland periods. Specifically, we summarize older investigations of Mound A, then present the results of recent terrestrial LiDAR documentation. Our work substantiates the claim that Mound A was the largest Woodland-period mound in Eastern North America in terms of overall volume.

A REASSESSMENT OF THE CHRONOLOGY OF MOUND A AT TOQUA

Abstract

The Toqua site (40MR6) is one of the most thoroughly excavated Late Mississippian mound sites in East Tennessee. The site has been a focal point of research on late prehistory in southern Appalachia, but there are issues surrounding its chronological placement. The radiometric dates obtained for the site in the 1970s and the archaeomagnetic dates reported in 1999 have large standard deviations. These dates are too imprecise to be useful for a temporal placement of the site that is clear enough for current discussions of the development of Mississippian culture. A newly obtained Accelerator Mass Spectrometry (AMS) date from the large platform mound (Mound A) allows a reevaluation of the occupation sequence of the Toqua site. This date provides an anchor for a refined chronology for Mound A. In addition to the new AMS date, this refined chronology is based on complementary lines of evidence, including architectural evidence, mortuary practices, pottery traditions, and shell gorget styles.

The First Mallorcans: Prehistoric Colonization in the Western Mediterranean

The paper aims to elucidate the first human colonization of the western Mediterranean island of Mallorca by answering such questions as: What was the cultural identity of the first archaeologically identifiable human settlers? What was the chronology of colonization? Where did the colonizers originate? And what were their contacts during the initial phase of settlement? It is based on recently acquired chronological data and on a review of the classical sources. A precise chronology for the first colonization event is proposed, supporting the idea that human settlement on Mallorca started within the period 2350–2150 cal BC. The coast of Languedoc, between the rivers Vidourle and Rhône, is the most probable source region. Whether the first settlers were derived from an Early Bronze Age or a Late Copper Age mainland culture remains unresolved. A rapid initial population growth following initial colonization is proposed. The available evidence points to the development of an essentially isolated population on Mallorca, developing an autochthonous culture with only limited contacts to mainland regions.
