As an alternative, we propose a framework focused on variation in material culture, architecture, and foodways between Jaketown and Poverty Point, the regional type site. Our analysis indicates that people used Poverty Point Objects and imported lithics at Jaketown by 4525–4100 cal BP—earlier than elsewhere in the region. By 3450–3350 cal BP, people intensively occupied Jaketown, harvesting a consistent suite of wild plants. Between 3445 and 3270 cal BP, prior to the apex of earthwork construction at Poverty Point, the community at Jaketown built at least two earthworks and multiple post structures before catastrophic flooding sometime after 3300 cal BP buried the Late Archaic landscape under alluvium. These new data lead us to conclude...

Jon Gibson excavated this unit and others in 1991 and argued that RW3 was constructed rapidly. We test the fast construction hypothesis by applying new methods (micromorphology, magnetic susceptibility, sequential loss-on-ignition) and by obtaining new radiocarbon dates. Before construction, the ground surface beneath RW3 was cleared and occupied. Preconstruction deposits are composed of anthropogenically enriched sediments. RW3 was constructed in layers of mixed heterogeneous natural and anthropogenically enriched sediments. The surfaces of these layers were used briefly during construction. The goal of the builders was to quickly raise the ridge to its full height. Magnetic susceptibility measurements and artifact density data show that the top of the constructed ridge is buried 10 to 30 cm below the modern surface. The construction of this section of RW3 was exceptionally rapid. The ridge was built after 3355–3210 cal BP and was under construction by at least 3450–2975 cal BP. Analysis of existing excavations offers great opportunity for pursuing vital research questions while having a limited effect on the integrity of archaeological deposits at Poverty Point.

In the lower Mississippi Valley (LMV) the Poverty Point culture defined this period of socio-political elaboration. However, following a significant period of climate change that led to exceptional flooding and a major reorganization of the course of the Mississippi River, this culture collapsed beginning ca. 3300-3200 cal yr BP and the LMV was abandoned for the subsequent 500 years. In this study, we use data from the Jaketown site in the Yazoo Basin of west-central Mississippi to refine the chronology of the climate event that caused the collapse of the Poverty Point culture. A large flood buried Poverty Point-era occupation deposits at Jaketown around 3310 cal yr BP. Lateral migration of the Mississippi River during flooding led to inundation of the Yazoo Basin and re-occupation of ancient river courses. A coarse sand stratum topped by a more than a meter-thick fining upward sediment package marks a crevasse deposit caused by a rupture of the natural levee at Jaketown. This levee breach was part of a larger pattern of erratic flooding throughout the LMV and is associated with major landscape evolution and the abandonment of Poverty Point sites within the valley. Early Woodland peoples re-colonized the crevasse surface after ca. 2780 cal yr BP. Following this event, the Jaketown site and the eastern Yazoo Basin witnessed a period of landscape stability that lasts to this day. These archaeological data demonstrate how climate change and natural disasters can lead to socio-political dissolution and reorganization even in relatively small-scale hunter-gatherer populations.

The ability to map archaeological sites at a landscape scale provides researchers the possibility to reconstruct and assess the ways humans organized, constructed, and interacted with their surroundings. However, LiDAR can be impacted by a variety of modern development and land use practices. In this article, we confront these issues by presenting the first examination of high-resolution LiDAR-derived imagery from Central Kentucky, part of the larger heartland for late-Early and Middle Woodland-era (ca. 300 BC-AD 500) Adena-Hopewell societies. Our investigations demonstrate that multiple issues can arise when analyzing LiDAR imagery for monumental earthen architecture in this region. We outline an integrated strategy to rediscover and confirm the presence of earthen architecture made by Adena-Hopewell societies that incorporates aerial photographs, multi-instrument geophysical surveys, and geoarchaeological methods into the examination of LiDAR imagery. This methodology will be applicable in other global contexts where archaeologists are seeking to rediscover ancient forms of earthen architecture within heavily disturbed or developed landscapes.

This paper acknowledges mound building as the purposeful selection of soils and sediments for specific color, texture, or engineering properties and the organization of deposits suggesting that the building process reflects both shared knowledge and communicates specific information. We present two examples: Late Archaic period Poverty Point site Mound A, and Mississippian period Shiloh site Mound A, in the exploration of structured deposits to identify ritual in contrast to a more mundane or purely practical origin. We argue the building of these earthen monuments was not only architecturally important as a means to serve a subsequent purpose but that the act of construction itself was a ritual process intended to serve its own religious and social purposes. In these contexts, ritual does much more than communicate underlying social relationships; it is instrumental to their production.

This deposit was associated with the site's Early Woodland component. Recent fieldwork at Jaketown also encountered the same tetrahedron deposit and identified an additional and distinct pit feature filled with the objects. In this article, we present the results of analyses that examine the production, composition, chronology, and function of these enigmatic baked-clay artifacts. Following a hiatus associated with massive flooding in the Mississippi Valley ca. 3200-2850 cal B.P., Jaketown was re-occupied by people who shared ceramic affinities with groups to the south and to the east and, who like many contemporaries, used BCOs as a part of their cooking technology. The tetrahedron deposit represents one of the earliest dated Tchula contexts at ca. 2600 cal B.P., and was used over a short time for a social purpose that brought populations together for food consumption as a means of encouraging cooperation.

These processes coincide with increased frequency and intensity of major floods along the Yellow River. The interactions between flooding and socialtechnical developments fundamentally reshaped politics of the Han and stimulated the formation of the so-called Heaven-Human Induction idealism. This Confucian environmental ethic gradually became a powerful orthodoxy that shaped political and economic behaviours and society's perspective on and actions towards utilising environmental resources and transforming landscapes. Similar processes played out in Three-Kingdoms Korea (300-668 AD). The Korean case exemplifies how, as in China, this idealism was a product of the long-term interplay between state formation and the environment through the development of intensive agriculture.

Humans began to modify site-specific and local-level environments in the Early Holocene (~11,500–7000 BP). By the Mid-Holocene (~7000–5000 BP), the effects of humans on the environment become much larger and are witnessed at regional and tributary river basin scales. Land clearance and agriculture, as well as related land use, are dominant determinants of these changes. By the Late Neolithic to Early Bronze Age (~5000–3500 BP), population growth and intensification of agricultural production expanded the human footprint across the Yellow River region. By the Mid to Late Bronze Age (~3600–2200 BP), larger populations armed with better technology and propelled by more c...

In this paper, we present palynological results from the Dahecun Core, Henan Province, China. Our pollen data indicate a warm and wet climate condition from 9200 to 4000 cal BP, which then switches to a cool and dry climatic condition during the Neolithic-Bronze Age transition (∼4000–3600 cal BP). We analyze 14C dates from archaeological sites to demonstrate four episodes of population increase and present vegetation dynamics, determined from available pollen data, to provide evidence for the synchronous shifts in vegetation and human population during the Neolithic. Our results indicate that the aridification in the early Bronze Age did not cause population collapse, highlighting the importance ...

Through a synthetic collaboration with archaeologists around the globe, Stephens et al. compiled a comprehensive picture of the trajectory of human land use worldwide during the Holocene (see the Perspective by Roberts). Hunter-gatherers, farmers, and pastoralists transformed the face of Earth earlier and to a greater extent than has been widely appreciated, a transformation that was essentially global by 3000 years before the present.

In this paper, we present palynological data from the early Bronze Age city of Dongzhao, Henan Province, China. Our data indicate that vegetation change and the development of early urban settlements are closely linked, with the advent of urban development significantly accelerating deforestation and altering the composition of local vegetation communities. The pollen record from Dongzhao provides new evidence to support the claim that urban expansion, coupled with a drying climate and the expansion of agriculture, dramatically reconfigured the landscapes of Bronze Age China.

This article explores archaeological evidence for crop cultivation, field-management practices and the use of farming implements at the Western Han (202 BC-AD 8) village of Sanyangzhuang in Henan Province, China. The authors analyse the implications of these practices for the newly developed smallholder mode of production. By combining diverse strands of evidence, this investigation provides new insights into the status of agricultural production in the Central Plains during the Western Han Dynasty.

In the North China Plain, the historical record suggests a long tradition of irrigation, but archaeologists have found scant evidence of these technologies outside of urban areas. In 2012, 2015, and 2016, our excavations at the Anshang site, Neihuang County, Henan Province, China, revealed several archaeological features that we interpret as evidence of Late Shang dynasty (ca. 1200-1046 B.C.) canal construction in a nonurban context. By using a range of geological methods, including particle size, loss on ignition, magnetic susceptibility, and micromorphology, we suggest that these ancient canals and the subsequent construction phases found at Anshang not only influenced the development of local geomorphic conditions, but also were part of early dynastic attempts to restructure the natural landscape to facilitate agricultural productivity. These irrigation canals found at Anshang may be representative of broader trends of human-environmental interactions in the North China Plain.

Our 2011 fieldwork south of the Erlitou site in the Luoyang Basin indicates that an unconformity dating to ca. AD 1100 is roughly coincident with a major southward shift in the lower course of the Yellow River. In AD 1128, the governor of Kaifeng breached the dikes of the Yellow River to impede an advancing army, causing the Yellow River to flow south out to the Yellow Sea. We argue that the dike breach not only changed the fluvial dynamics of the Yellow River but also switched the rivers in the Luoyang Basin from an aggrading to an incising system. The resumption of sedimentation in the Luoyang Basin is roughly coincident with the next major shift of the Yellow River’s main course northward to the Bohai Sea in AD ...

By identifying anthropogenic additions into ancient soils, archaeologists can understand many of the social and geological processes that formed ancient landscapes. We present geoarchaeological research from the Sanyangzhuang site, Henan Province, China, to examine how this area's long history of agricultural production altered soils from the Neolithic to the Iron Age. We use soil micromorphology and geochemistry to study the anthropogenic residues left behind in ancient soils and compare our results with the historical and archaeological records. Our results suggest that the transition from wooden to iron tools at the beginning of the Iron Age played an important role in the long-term formation of ancient agricultural soils at Sanyangzhuang, and by extension, in much of ancient China.

We use archaeological and environmental data to show that there was a significant marine transgressive event that began before 9000 cal. BP. This event reached its maximum extent inland and had the greatest impact on the Jiangsu region between 9000 and 8000 cal. BP. Because of this transgression, most of the low-lying parts of modern Jiangsu Province were either covered by seawater or were converted to a wetland environment that was unsuitable for long-term human settlements until ca. 7000 cal. BP. Between 7000 and 6000 cal. BP, the sea retreated and new lands became available for colonization. Humans rapidly moved into the newly emerged lands, which were ecologically rich with diverse and abundant plants, animals, fish, and shellfish. Evidence that human settlement were earliest in the northwest and generally expanded south and east. The Taihu Plain was rapidly occupied, but because of variations in topography, hydrology, and sea level changes, the Lixiahe Plain remained a coastal lagoon until 6000-5500 cal. BP.

Although the surrounding environment is an extremely arid desert now, abundant archaeological remains indicate that human occupation was common during certain periods in the Holocene. Field investigations and laboratory analyses of a sediment profile near the Xiaohe Cemetery indicate that while the regional environment was arid desert throughout the Holocene there were three episodes of lake formation near the site in the periods 4.8-3.5 ka BP, 2.6-2.1 ka BP and 1.2-0.9 ka BP. Geomorphic and hydrological investigations reveal that a lake or lakes formed in a low-lying area when water was derived initially from the Kongque River and then shunted into the Xiaohe River basin. Low amounts of active chemical elements in lacustrine sediment between 4.8-3.5 ka BP indicate abundant and continuous water volume in the lake; the content of active chemical elements increased between 2.6-2.1 ka BP but was still at a relatively low level, suggesting a declining amount of water and diminished inflow. Between 1.2-0.9 ka BP there was a very high content of active elements, suggesting decreased water volume and indicating that the lake was stagnate. In contrast, the general climate condition shows that there had a warm-humid stage at 8-6 ka BP, a cool-humid stage at 6-2.9 ka BP and a warm-dry stage at 2.9-0.9 ka BP in this region. The hydrological evolutions around Xiaohe Cemetery did not have one-to-one correspondence with climate changes. Regional comparison indicates that broad-scale climatic conditions played an important role through its influences on the water volume of the Tarim River and Kongque River. But, the formation of the lakes and their level were controlled by geomorphic conditions that influenced how much water volume could be ZHANG Yifei et al.: Holocene environmental changes around Xiaohe Cemetery and its effects on human occupation 753 shunted to Xiaohe River from Kongque River. Human occupation of the Xiaohe Cemetery and nearby regions during the Bronze Age and Han-Jin period (202 BC-420 AD) corresponded to the two earlier lake periods, while no human activities existed in the third lake period because of the decreased water volume.

This paper extends the geography of this conceptual framework by moving south of the Qinling Mountains-Huai River divide, incorporating sites in South China that associated with the beginnings of rice exploitations. We highlight the continuous mountain chains running from the Greater Khingan range in the northeast to the Nanling Mountains in the south that give form to China's Fertile Arc. Key sites in the northern part of the Arc are situated along China'-hi lly flanks‖ while southern sites are located in a diverse array of landforms including piedmont plains and intermountain basins. A parallel could be drawn in the context of early land choice ‗ecological opportunism' between the Fertile Crescent and China's Fertile Arc.

Preservation is exceptional, both at the village of Sanyangzhuang itself and, by dint of satellite reconnaissance, over a vast landscape contemporarily covered by the flood. Deep profiles show that here land surfaces of the Neolithic and Warring States periods also lie buried. The potential for the study of the early agricultural sequence and a deeper knowledge of Han society is truly outstanding. The discoveries also offer a vivid account of the way a settlement was overwhelmed by flooding.
