Lothagam North Pillar Site

Last updated February 11, 2024

The Lothagam North Pillar Site, registered as GeJi9, is an archaeological site at Lothagam on the west side of Lake Turkana in Kenya dating to the Pastoral Neolithic and the Holocene. It is a communal cemetery, built between 3000 BCE and 2300 BCE by the region's earliest herders as rainfall in the area decreased and Lake Turkana receded.^[1]^[2]^[3] It is thought to be eastern Africa's largest and earliest monumental cemetery.^[4]

The burial site study and excavation were led by Elisabeth Hildebrand from 2009 to 2014.^[1] The burial site is flanked by megaliths, stone circles, and cairns, and is believed to hold the remains of hundreds of individuals.^[3] Many of the people buried at Lothagam North were adorned with stone beads, ivory, animal teeth, rings, or other ornaments.^[2]

Context

Between 12,000 and 5,000 years ago, tropical Africa experienced significant climate change resulting in increased humidity and a northward shift of vegetation zones and fauna. This time period is referred to as the African Humid Period, and during the Early and Middle Holocene, North and East Africa had a humid climate with full lakes and diverse water animals.^[5] The first herding economies emerged during this period, with sheep, goats, and cattle spreading rapidly through the Central Sahara and Nile Valley. As aridity increased in the Sahara Desert, specialized forms of pastoralism emerged and populations shifted out of the region.^[6]

The Lothagam North Pillar Site, situated in the Lake Turkana Basin of East Africa, provides extensive evidence of Early and Middle Holocene pastoralism and adaptations. The site shows that people adjusted to various ways of living, including ceramic use and the hunting and gathering of aquatic resources, as well as relying on livestock and herding.^[5]

History of occupation

During the African Humid Period, the Lothagam North Pillar Site displayed a unique and distinctive monumental tradition amongst significant environmental shifts.^[1] The changing climate caused the lake to recede revealing fertile land for herbivores to feed on, and people began to migrate into northwest Kenya, bringing cattle and herding practices.^[4] As people adapted to changes in the environment, they developed new technologies and social networks. However, around 3300 BCE, the African Humid Phase came to an end in the Turkana region, and the lake level dropped again.^[1] Towards the end of the African humid period, when drier conditions began, nomadic peoples of pastoralist hunter-gatherer communities would return to the site to bury their dead.^[3]^[7]

The construction and use of the site ended at the end of the humid period by 2300 BCE. The site is the oldest of six known pillar sites in the area and was in use for almost five hundred years.^[4] The architectural elements, such as cairns, stone circles, and platforms, indicate that the site was completed. The change in the climate or new diseases resulting in cattle losses may have forced the local inhabitants to move elsewhere.^[3] It is also possible that social changes and other factors played a role in the decrease in communal burial practices, as these customs were not observed in other herding populations in the Lake Turkana region.^[1]

Excavation

The Lothagam North Pillar site situated in Kenya features two volcanic ridges oriented in a north-south direction and a trough between them containing deposits ranging from the Pliocene to the Holocene era. GeJi9 is located roughly 1 km northwest of early Holocene beach deposits and is separated into eastern and western sections. The western area is a circular platform supported by three pillars, while the eastern portion consists of six cairns and nine stone circles.^[8]

The platform surrounded by boulders on the western side of the Lothagam site covers an area of 700 square meters and contains a mortuary cavity, which is estimated to hold anywhere from 585 to 1,053 individuals.^[1] Recent research published in the Journal of Anthropological Archaeology has argued that the cemetery was for all members of this community, not just the leaders.^[6]^[9] The site yielded 30 excavated burials containing the remains of at least 44 individuals, including both males and females of different ages, and most of them were buried with ornaments.^[6] Data from excavations and ground-penetrating radar (GPR) reveal that the cemetery was a planned and multi-generational project.^[10] The mortuary cavity was built by removing beach sands from a large area down to sandstone bedrock. Each person was buried approximately 3 feet (0.91 m) deep in a smaller cavity. At the bottom of the mortuary cavity, pits with additional burials were carved into soft sandstone bedrock.^[3] The entire platform was then filled with rubble and capped with basalt pebbles, and natural basalt pillars were brought in and placed surrounding the platform’s east side.^[1]

On the eastern side, excavations occurred around one stone circle and one cairn. The largest cairn at Lothagam North, covering 57 square meters, is surrounded by massive sandstone slabs. The stone circle, a 16 square meter ring of sandstone and basalt cobble, covers a small, central bedrock pit containing remains and artifacts of at least three persons of distinct ages. The stone circle’s compact spacing and size are similar to the arrangement of burials and pits within the western platform.^[1]

Archaeological finds

Human remains

Within Lothagam North’s platform on the western side, the mortuary cavity contains tightly arranged skeletal remains of all ages and sexes. Excavations of more than 44 individuals revealed that some of the burials were delayed, indicated by disorganized bones.^[1] Two-thirds of burials contained bent and folded individuals in various positions and were often capped with a sandstone or basalt boulder.^[6] On the edge of the cavity, excavation uncovered three skulls and dismembered body parts. The strategic placement of bodies allowed for maximum use of space, with variable body positions and orientations. Evidence shows that areas remained undisturbed after burial.^[1]

Ornamental remains

Nearly all skeletons found at the site were adorned with personal ornaments. These included ostrich eggshell or stone beads around the neck, ivory rings, pendants, earrings, and bangles. Two burials contained decorated headpieces adorned with intricate arrangements of mammal teeth. Another individual was buried with 12 perforated hippo tusks that may have represented jewelry of some sort. The burial pit yielded some caprine remains, as well as a carved stone palette that mimicked a cow. Adornments were found across all age groups and sexes, indicating that ornamentation was the norm. Over 300 vibrantly colored stones and minerals beads were found in 20 burials. The beads consisted of 36 raw materials, including soft materials such as pink analcime, dark green talc, and purple fluorite, and harder minerals such as bright blue-green amazonite and chalcedony. Many volcano-derived rocks, such as amygdaloidal and vesicular basalt, rhyolite, and phonolite, were found that are available locally, but other rocks like amazonite and talc only exist around other parts of the Turkana Basin, suggesting frequent travel to and from the site.^[1]

Ceramics

The GeJi9 ceramic assemblage was found to be from the middle Holocene times and includes 145 rim sherds from 99 vessels, with one of the vessels being gourd-shaped. Several vessels are complete, but 79 only consist of fragmented sherds. Most of the vessels are closed-mouth bowls that range from 5-22 cm in diameter, and some are decorated with grooves or incisions, Classic Nderit patterns, or burnished ripples. The vessels' paste contains volcanic material, and quartzose particles, and some vessels show faint amounts of mica. Although oxidation is usually incomplete, most sherds appear to be well-fired.^[8]

Lithics

The two excavation units at GeJi9 yielded a total of 258 lithic artifacts, mainly consisting of obsidian micro-debitage (small flakes less than 2 cm in size) which are similar to those found at the Jarigole pillar site, which is contemporenous to this site. Very few flakes have cortex on more than half of their surfaces, indicating that the raw material was brought from far away and that the cores were carefully selected. The six cores found are single-platform prismatic blade cores, and only one tool, identified as a scraper, was found.^[8]

Faunal remains

Very few faunal remains were found at the site. Ostrich eggshell beads and mammal bone fragments including teeth were found in the burials on the western side. The platform also contained remains of other mammals, caprine, and fish below the stone slabs, but no microfauna or birds.^[8]

Discussions

Mortuary practices

Anthropologists’ interpretations of the mortuary practices at the Lothagam North Pillar Site have evolved over time. Early theories from a processual standpoint focus on social organization as the main factor, with the age, sex, and social status of the deceased accounting for the variation between individuals. Middle-range theorists emphasize functional explanations for mortuary behaviors, linking the establishment of cemeteries to territoriality and control over resources. Post-processual scholars take a more contextual approach, considering factors such as religious beliefs and physical circumstances surrounding death. Contemporary mortuary archaeologists use a mix of these theories, recognizing the complex social factors within material and cultural perspectives that shape funerary practices. While there is no universal explanation for the construction of the Lothagam North Pillar Site among early pastoralists and fisher hunter-gatherer communities, the presence of other pastoral cemeteries in mid-Holocene Africa suggests that mobile groups shared a similar social role within the spread of herding and social networking.^[6]

Abandonment

The reasons for the site’s abandonment remain unclear. However, in cases where pastoralism was introduced to a new area, cemetery creation often followed, particularly during major environmental shifts as seen in the Lothagam North Pillar Site. With unpredictable resource and trade distributions following the end of the African Humid Period, incoming herders faced challenges such as new landscapes, forage patterns, rainfall cycles, predators, diseases, and water sources. They may have also encountered diverse hunter-gatherer communities undergoing their own economic struggles due to changing environmental conditions.^[6]

The first herders in any area would have faced various challenges when adapting livestock strategies to new or changing environments, such as uncertain resources, unfamiliar weather patterns, and diverse hunter-gatherer communities. These challenges, combined with social tensions arising from interactions between different cultures and economies, may have led to the abandonment of the Lothagam North Pillar Site.^[6]

Significance

The occupation of the Lothagam North Pillar Site and surrounding pillar sites in northwest Kenya were brief, and their absence in other areas suggests that they contributed to important social and economic transformation during their time period.^[11] At Lothagam North Pillar Site, a communal cemetery was constructed over a few centuries amidst all of the social and economic tensions of a dynamic landscape. The site may have served as a landmark for mobile people to express unity through shared ritual, promoting trade, information sharing, and strategic planning of livestock movements across multiple areas. The development of the site supports this idea, suggesting that monumentality helped lessen social and economic challenges.^[1]

Ethnographic and ethnohistoric accounts of eastern African herders and hunter-gatherers offer insights into the possible functions of pillar sites. They describe motivations for construction, including ceremonial, cultural, and religious practices that involved the establishment of social statuses and the gathering of mobile populations. Archaeologists can use this knowledge, even if the practices are different from the past, to test hypotheses about the uses of pillar sites.^[11]

The construction of monumental sites and mortuary customs indicate complex social forms that involve cooperative efforts of large groups to create reminders of shared history and cultural values.^[1] The Lothagam North Pillar Site provides insight into the social networks and cooperation of small-scale mobile societies without emerging social hierarchies, and researchers investigating pastoral frontiers in other parts of the world can use this data to consider a broad range of possible explanations for such sites.^[11] Furthermore, the archaeological record can enrich anthropological understanding of the strategies that led to pastoralist success, which can offer solutions to challenges that exist today, such as globalization, climate change, and urban development.^[6]

Ngenyn is a Late Stone Age and/or a Savanna Pastoral Neolithic archaeological site located in the Kapthurin River Basin, which is part of the Tugen Hills, west of Lake Baringo. It falls within the Baringo County in north central Kenya. The occupied area is situated on the floodplain of the River Ndau's confluence with the Sekutionnen River, on a widespread terrace called the Low Terrace, the top of which is about 3m above the level of the modern river. The site was initially discovered by Louis Leakey in 1969. It was visible as a large exposure of bones, stone tools and pottery eroding out of the terrace. The site was excavated in the late 1970s as part of Francoise Hivernel's PhD research. Ngenyn remains the only Late Holocene site excavated in the Lake Baringo Basin and in general very little archaeological work has been done on the Late Holocene within the Baringo County.

The Savanna Pastoral Neolithic is a collection of ancient societies that appeared in the Rift Valley of East Africa and surrounding areas during a time period known as the Pastoral Neolithic. They were South Cushitic speaking pastoralists who tended to bury their dead in cairns, whilst their toolkit was characterized by stone bowls, pestles, grindstones and earthenware pots.

The Pastoral Neolithic refers to a period in Africa's prehistory, specifically Tanzania and Kenya, marking the beginning of food production, livestock domestication, and pottery use in the region following the Later Stone Age. The exact dates of this time period remain inexact, but early Pastoral Neolithic sites support the beginning of herding by 5000 BP. In contrast to the Neolithic in other parts of the world, which saw the development of farming societies, the first form of African food production was nomadic pastoralism, or ways of life centered on the herding and management of livestock. The shift from hunting to food production relied on livestock that had been domesticated outside of East Africa, especially North Africa. This period marks the emergence of the forms of pastoralism that are still present. The reliance on livestock herding marks the deviation from hunting-gathering but precedes major agricultural development. The exact movement tendencies of Neolithic pastoralists are not completely understood.

Kanapoi is a paleontological site in the Kenyan Rift Valley, to the southwest of Lake Turkana. Fossils were first found at Kanapoi in the 1960s by a Harvard expedition, and later by expeditions from the National Museums of Kenya.

Gogo Falls is an archaeological site near a former and since 1956 dammed waterfall, located in the Lake Victoria Basin in Migori County, western Kenya. This site is important to archaeology as it includes some of the earliest appearances of artifacts and domestic animals in the area. The findings at the site help to reconstruct the later prehistory around Lake Victoria, including a Pastoral Neolithic occupation by Elmenteitan peoples and a later Iron Age occupation. Artifacts found at the site included pottery and iron artifacts. Through these artifacts some of the cultural traditions of the people who lived near Gogo Falls were discovered.

Njoro River Cave is an archaeological site on the Mau Escarpment, Kenya, that was first excavated in 1938 by Mary Leakey and her husband Louis Leakey. Excavations revealed a mass cremation site created by Elmenteitan pastoralists during the Pastoral Neolithic roughly 3350-3050 BP. Excavations also uncovered pottery, beads, stone bowls, basket work, pestles and flakes. The Leakeys' excavation was one of the earliest to uncover ancient beads and tools in the area and a later investigation in 1950 was the first to use radiocarbon dating in East Africa.

Nataruk in Turkana County, Kenya, is the site of an archaeological investigation which uncovered the remains of 27 people. It dates between 9,500 and 10,500 BP. The remains have garnered wide media attention for possible bioarchaeological evidence of interpersonal violence, i.e. prehistoric warfare.

The Elmenteitan culture was a prehistoric lithic industry and pottery tradition with a distinct pattern of land use, hunting and pastoralism that appeared and developed on the western plains of Kenya, East Africa during the Pastoral Neolithic c.3300-1200 BP. It was named by archaeologist Louis Leakey after Lake Elmenteita, a soda lake located in the Great Rift Valley, about 120 km (75 mi) northwest of Nairobi.

Megaliths in Ethiopia are large, monumental stones, that exist in Ethiopia.

Nderit pottery is a type of ceramic vessel found at archaeological sites in Africa, particularly Tanzania and Kenya. Nderit pottery, previously known as ceramic tradition "Gumban A ware," was initially documented by Louis Leakey in the 1930s at sites in the Central Rift Valley of Kenya.Stylistic characteristics of Nderit pottery discovered in the Central Rift Valley include an exterior decoration of basket-like and triangular markings into the clay’s surface. The vessels here also have intensely scored interiors that do not appear to follow a distinct pattern. Nderit Ware exemplifies the transition from Saharan wavy-line early Holocene pottery towards the basket-like designs of the middle Holocene. Lipid residue found on Nderit pottery can be used to analyze the food products stored in them by early pastoralist societies.

Pastoral rock art is the most common form of Central Saharan rock art, created in painted and engraved styles depicting pastoralists and bow-wielding hunters in scenes of animal husbandry, along with various animals, spanning from 6300 BCE to 700 BCE. The Pastoral Period is preceded by the Round Head Period and followed by the Caballine Period. The Early Pastoral Period spanned from 6300 BCE to 5400 BCE. Domesticated cattle were brought to the Central Sahara, and given the opportunity for becoming socially distinguished, to develop food surplus, as well as to acquire and aggregate wealth, led to the adoption of a cattle pastoral economy by some Central Saharan hunter-gatherers of the Late Acacus. In exchange, cultural information regarding utilization of vegetation in the Central Sahara was shared by Late Acacus hunter-gatherers with incoming Early Pastoral peoples.

The prehistory of East Africa spans from the earliest human presence in the region until the emergence of the Iron Age in East Africa. Between 1,600,000 BP and 1,500,000 BP, the Homo ergaster known as Nariokotome Boy resided near Nariokotome River, Kenya. Modern humans, who left behind remains, resided at Omo Kibish in 233,000 BP. Afro-Asiatic speakers and Nilo-Saharan speakers expanded in East Africa, resulting in transformation of food systems of East Africa. Prehistoric West Africans may have diverged into distinct ancestral groups of modern West Africans and Bantu-speaking peoples in Cameroon, and, subsequently, around 5000 BP, the Bantu-speaking peoples migrated into other parts of Sub-Saharan Africa.

The Jarigole pillar site is one of the megalithic communal cemetery sites in Lake Turkana Basin in Northern Kenya associated with the Pastoral Neolithic period. The site is located on the eastern shores of Lake Turkana in the southeastern edge of the Sibiloi National Park. Situated in a recessional beach which is 70 meters above the 1973 lake level, the site includes oval platforms >1000 sq m with a circular mound, and 28 basalt pillars each weighing about 200 kg and moved over a distance of 2 km from the site. The site is believed to have been constructed by the first wave of ancient herders who migrated to the region down from the Sahara around 5000 years ago, a period marked by rapid climatic, economic and social change.

Manemanya (GcJh5) is an archaeological site within the Lake Turkana basin in northern Kenya. It is a communal burial site built almost 5,000 years ago and is associated with the advent of pastoralism in eastern Africa during the Pastoral Neolithic period. Manemanya is located 1 km east of Lesodok hill, on the western shores of Lake Turkana. Comprising nine pillar clusters situated across two distinct zones, this site lacks evident platform mounds or cairns. However, its distinctiveness is marked by the presence of cobbles in the central area, a distinguishing feature that sets it apart from the natural surface surrounding the site, presenting a notable contrast with other pillar sites in the Lake Turkana basin.
