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.     

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.     

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.     

Serpent Mound: Still Built by the Adena,and Still Rebuilt During the Fort Ancient Period

Radiocarbon dates from the base of Serpent Mound in Ohio demonstrate that it was built 2,100–2,300 years ago during the Adena period but was subsequently rebuilt or repaired about 900 years ago during the Fort Ancient period. We describe the basis for supporting the chronology of this building sequence, why it is the best and most complete explanation from the data at hand, and discuss the errors and misconceptions that critics of it have put forth. Our interest is in establishing a chronology of mound construction in order to address questions about cultural continuity/discontinuity, appropriation, and reuse of cultural monuments and religious/political symbols. We also plead that researchers jointly collect new data from Serpent Mound to end the back-and-forth questioning of chronological context and research competence.     

Rejoinder to Lepper Concerning Serpent Mound

In this article we address comments made by Bradley Lepper concerning our previously published article, “Radiocarbon Dates Reveal Serpent Mound is More than Two Thousand Years Old” (Romain, Herrmann, Monaghan, and Burks 2017). Further we offer commentary on the new radiocarbon dates provided by Lepper (this volume).     

The Case of the Caldwell Mound: A Woodland Period Mound in the Central Scioto River Valley

ABSTRACT

This article presents a reconstruction and analysis of the Caldwell Mound located in the central Scioto River valley of southern Ohio. The mound contained a log tomb, at least four burials, and associated funerary objects. Four AMS radiocarbon dates place the Caldwell Mound within the last century BC and first century AD, and the mound contains evidence of practices historically associated with “Adena” and “Hopewell.” Few other records exist from this period in the region despite it experiencing perhaps some of the most dramatic socioreligious transformations in precolumbian North America. This analysis documents early evidence for the diversification and segregation of leadership roles based on the interpretation of three buried individuals. It also demonstrates the utility and efficacy of working with amateur-produced records and collections, even when incomplete, to reconstruct and glean insight from important Woodland period sites.     

The Myrick Park Mounds (47Lc10), an Effigy Mound Site in Western Wisconsin

The earliest documented excavation of an effigy mound group by a professional archaeologist occurred in 1883 when Frederic Ward Putnam and local acquaintances excavated portions of four mounds at the Myrick Park site (47Lc10) in La Crosse, Wisconsin. Putnam worked on one effigy (similar to the short-tailed turtle form) and three conical mounds. Theodore H. Lewis visited the site in 1885 and mapped one additional conical mound. We examined documentation and collections housed at the Peabody Museum of Archaeology and Ethnology at Harvard University. Artifacts include a portion of a Madison Cord Impressed jar (a common Effigy Mound offering) and a trailed rim sherd similar to terminal Late Woodland types. Human remains represent a minimum of 23 individuals: 18 adults and 5 subadults. Dental and skeletal evidence indicates a relatively healthy population with low levels of nutritional deficiency, early life stress, and trauma, similar to other regional Late Woodland populations.     

EARLY WOODLAND SETTLEMENT AND MOUND BUILDING IN THE UPPER TENSAS BASIN,NORTHEAST LOUISIANA

Abstract

Traditionally overlooked because it lacks hallmarks of material and cultural complexity, Early Woodland in the Southeast is an interval of significant transformation in material culture, settlement, and social organization. Investigations at four sites in northeast Louisiana provide insights into changes taking place at this time. These sites are situated on a crevasse splay created by flooding at the end of the Archaic. This flooding is associated with an occupation hiatus ca. 3000–2500 cal B.P. Evidence suggests a rapid colonization of the crevasse splay by people using Tchefuncte pottery, and there is no evidence at these sites of stratigraphic or cultural continuity from Poverty Point. The Early Woodland occupation in the study area dates ca. 2400–2100 cal B.P., which is later than dates associated with Early Woodland in the Pontchartrain Basin and contemporary with Lake Cormorant culture sites farther north. Early Woodland in northeast Louisiana is marked by a diagnostic Tchefuncte ceramic assemblage and the presence of a settlement system composed of small villages or hamlets nucleated around a conical mound that presumably served as a ceremonial/ritual center. This mound was erected very rapidly; radiocarbon dates suggest it was constructed in no more than 10 years. Although mound building has been suspected, this is the first conclusive evidence it was an aspect of Tchefuncte settlement and ceremonial practices. Data from these sites bear on the question of cultural and demographic continuity and change at the Archaic to Woodland transition. Previous models emphasize continuity of populations with ceramic technology and styles diffusing into the lower Mississippi Valley. In contrast, our data support a model of Early Woodland repopulation of the lower Mississippi Valley from the south and east following a prolonged period of regional abandonment.     

Mounds,Towns, and their Surrounds: An Archaeological,Historical, and Geophysical Approach to Burial Mounds,Residential Space,and Cultural Landscapes of the Late Woodland Springwells Site (a.d. 800–1400) at Historic Fort Wayne,Detroit

Historic Fort Wayne is located on the Detroit River in a landscape of heavy industry and marginalized urban neighborhoods (figure 1). Geophysical survey south of the Fort Wayne Mound—a Late Woodland Period burial mound enclosed by the Fort—indicates that pre-contact residential structures may be preserved at the site. Residential sites with mortuary monuments are uncommon in southeastern Michigan and represent an opportunity to better understand variation in Late Woodland settlement. Our approach combines existing archaeological research, historical records, and non-invasive geophysical survey in a culturally sensitive Native American site context presently unavailable for conventional archaeological excavation. We examine archaeological and historical records from Springwells and Late Woodland period settlements in the region to contextualize geophysical evidence from the site. The research prioritizes protection of Native American heritage sites in urban contexts together with ongoing archaeological interpretation of the Late Woodland cultural Landscape.     

Radiocarbon Dates on Textile and Bark Samples from the Central Grave of the Adena Mound (33RO1), Chillicothe,Ohio

The Adena Mound (33RO1) is the type site of the Adena culture, yet there have been no radiocarbon dates to place it reliably within a temporal framework. Fortunately, the artifact collection, curated by the Ohio Historical Society, includes objects that are highly suitable for radiocarbon dating, including fragments of textiles and tree bark associated with the central burial. We selected a textile fragment and two bark fragments for radiocarbon dating. The textile exhibits alternate pair twine with very fine yarns probably composed of cellulose bast fibers. The bark is from a black locust (Robinia pseudoacacia) tree. The results of the radiocarbon dating indicate that the Adena Mound was constructed between the end of the second century B.C. and the beginning of the first century A.D., placing it near the midpoint in the sequence of radiocarbon-dated Adena culture sites. This study demonstrates the value of museum collections for gleaning new data from curated materials.     

Connecting Heaven and Earth: Interpreting Early Woodland Nonmortuary Ceremonialism in Northern Ohio

Most previous studies of Early Woodland ritual and ceremonialism in the Ohio region have focused primarily on Adena mound and earthwork enclosures and their attendant mortuary facilities. Recent investigations of other constructions, such as circular post structures, have demonstrated the feasibility of expanding interpretations of Early Woodland ceremonialism to include nonmortuary contexts. In the southern drainages of Lake Erie, small hilltop enclosures are potentially fruitful localities for the study of (non-Adena) ritual and ceremonialism. Recent investigations at the Heckelman hilltop enclosure reveal nonmortuary-ceremonial activity during the Early Woodland period. Archaeological remains point to the construction of an oval ditch enclosing clusters of freestanding (ritual) poles and pits that exhibit evidence of having been used for preparing and serving ceremonial meals. It is proposed that the Heckelman ceremonial precinct was the site of ritually charged activities bearing important cosmological significance for its users.     

Mortuary Practices,Cultural Context,Bayesian Chronology,and Maize Consumption among Terminal Late Woodland Societies in Northeastern Illinois

In 1940, Gretchen Cutter and a WPA crew conducted excavations in the Mound Wi^o5 at the Fisher site in Will County, Illinois. We examined those materials as part of our reanalysis of the Fisher site excavations by George Langford and the University of Chicago. The mound’s material culture correlates with the Des Plaines phase but contains strong connections to the east, especially with Albee phase mortuary practices. Calibrated ¹⁴C dates and Bayesian modeling place the Des Plaines phase as contemporary with the Mound Wi^o5 mortuary’s primary use during the ninth to eleventh centuries. There is isotopic evidence of a mixed C₃/C₄ diet with some maize consumption. Mound Wi^o5 represents the only Terminal Late Woodland collective mortuary facility currently known in northeastern Illinois. The identification of such multigenerational communal Terminal Late Woodland mortuary practices lends support to the contention that they provided the cultural base for the emergence of the distinctive Langford Tradition accretional mortuary mounds.     

Petrographic Analysis of Late Woodland and Middle Mississippian Ceramics at the Iva Site (47Lc42), Onalaska,Wisconsin

The Iva site contained a rare effigy mound and Middle Mississippian (Ramey horizon) component within the Late Woodland Lewis phase territory of the Upper Mississippi River valley. Salvage excavations in 2002–2003 recovered fragments of numerous Angelo Punctated, Powell Plain, and Ramey Incised vessels, including examples of Angelo and Ramey in direct association. Petrographic analysis was conducted on seven grit-tempered and six shell-tempered vessels, eight of which are stylistically Mississippian. The results indicate that four of eight Mississippian vessels were likely manufactured in the American Bottom, with the other half being local imitations of Mississippian styles. These data are compared to contemporaneous Ramey horizon components in the Driftless Area of Cahokia's northern hinterland.     

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 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.     

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.     

THE CHRONOLOGY OF MONKS MOUND

Abstract

Monks Mound is the largest single Native American construction in North America. The mound sits at the center of the Cahokia site, and interpretations of its construction and use are fundamental for understanding how Mississippian peoples created mounds and landscapes. In the past, researchers speculated that Monks Mound was both one of the oldest and longest-lived monuments at Cahokia. Using a Bayesian computer model that incorporates both archaeological information and radiocarbon dates, I argue the mound is younger and was built more rapidly than previously thought. The mound likely was built in two very rapid efforts spanning fewer than twenty years. This analysis shows Cahokian society could mobilize vast quantities of labor for short periods, which may have inhibited institutionalized, transgenerational sociopolitical hierarchies.     

EARLY VILLAGE LIFE IN SOUTHEASTERN INDIANA: RECENT FIELD INVESTIGATIONS AT THE GUARD SITE (12D29)

Abstract

Investigations at the Guard site (12D29), located in Dearborn County, Indiana, have provided evidence pertaining to the development of early Fort Ancient villages. Recent geophysical survey and excavations alongside many new radiocarbon dates have allowed for improved understanding of household architecture and intrasite variability. Although some scholars have hypothesized that Middle Fort Ancient villages developed out of small early Fort Ancient hamlets, the Guard site provides explicit evidence for villages early in the Fort Ancient sequence. Guard also contains key Mississippian indicators for interaction, particularly wall-trench architecture and a Ramey knife. These findings demand that we reconceptualize the inception of Fort Ancient villages.     

CHRONOLOGY,SITE FORMATION,AND THE WOODLAND-MISSISSIPPIAN TRANSITION AT BAYSHORE HOMES,FLORIDA

Bayshore Homes (8PI41) is a large mound and midden complex on Florida’s west-central Gulf Coast that was investigated originally by William Sears in the 1950s. From 1999 to 2009, the authors conducted survey, test excavations, and soil coring to address questions regarding site formation, chronology, and cultural affiliation. Radiocarbon dates and ceramic analysis indicate two separate occupations during the Woodland and Mississippi periods, cal. A.D. 140–565 and cal. A.D. 890–1390 (2 sigma). The earlier occupation is associated with the Manasota archaeological culture, sand-tempered plain pottery, burials in midden deposits, and interments in a sand mound accompanied by Weeden Island–related mortuary ceramics. The later occupation is associated with Weeden Island–related decorated and Pinellas Plain ceramics in midden deposits and represents the transition from terminal Weeden Island to the Englewood phase of Early Safety Harbor. A large burial mound and a platform mound are associated with this period of site use. Our results also indicate that the unusual ceramic sequence identified by Sears in the site’s large shoreline shell midden is the result of redeposition, which occurred sometime after cal. A.D. 1220. Possible explanations for the redeposition event include monumental mound construction or the elevation of the midden ridge to serve as a foundation for structures to protect them from rising sea levels or storm surges.     

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.
