Study reveals changes in the development of downtown Cahokia

Published

Researchers have revealed the changes in the organisation and use of space in downtown Cahokia, by conducting scientist studies on the western edge of the Grand Plaza.

Cahokia was the largest urban settlement to develop from the Mississippian culture, a mound-building pre-Columbian civilisation that developed in the Midwestern, Eastern, and South-eastern United States.

The area was first inhabited as early as the Late Archaic period around 1200 BC, but the original builders are believed to have settled in the region around AD 600-700 during the Late Woodland Period.

At its peak, Cahokia had a population of up to 20,000 inhabitants, who constructed 120 earthen mounds that involved moving 55 million cubic feet of earth over a period several decades.

The study was conducted by researchers from the Appalachian State University, University of North Carolina, Washington University in St. Louis and the Colorado State University.

The team applied a magnetometer and electromagnetic induction survey at the western edge of the Grand Plaza and compared their results with LiDAR-derived visualisations and aerial photography.

This has revealed new information on the nature and sequence of monument construction in Downtown Cahokia, as well as architectural changes in domestic and special-use structures.

The team found that monumental architecture contributed to the overall aesthetic of this public space, in particular with mounds 48 and 57 that form the western end of the Great Plaza.

Geophysical data has also shown the extant of building growth and decline over the centuries in the Great Plaza area, with 17 buildings from the Terminal Late Woodland/Emergent Mississippian period (AD 925–1050), 10 buildings during the Lohman Phase (AD 1050–1100), 5 buildings during the Stirling Phase (AD 1100–1200), and 9 buildings in the Moorehead Phase (AD 1200–1275).

The study has also found changes in the sequence of palisade walls around the Grand Plaza, where they observed a correlation between identified palisade remnants and a small linear rise that is roughly 4.5 m wide, and encapsulates mounds along the east, south, and west of the Grand Plaza.

According to the researchers: “Our study reinforces the notion that the founding and occupation of Downtown Cahokia resulted in the creation of a heavily palimpsestic landscape that was continually transformed according to the situational needs of the communities that were enmeshed within and influenced by the site’s historical trajectory.

Drawing on the combined examination of multiple geospatial and remote sensing datasets has consequently permitted us to draw out the interplay between the societies that participated in the creation of Cahokia and the changes they left inscribed into the landscape.”

Ancient Pueblo used conch-shell trumpets for communication

Published

A new study, published in the journal Antiquity, suggests that the ancient Pueblo culture used conch-shell trumpets for communication.

The focus of the study is the site of the Chaco Canyon in north-west New Mexico. Located in Chaco Culture National Historic Park, Chaco Canyon contains numerous small dwellings and multi-story buildings known as great houses.

Based on the density of structures, archaeologists speculate that the site was once a bustling metropolis, inhabited by as many as 2,300 people during its height from AD 1050 to 1130.

Conch-shell trumpets have been found in burial contexts at Chaco Canyon, which today are used in contemporary Pueblo ritual practices.

Using a Soundshed Analysis model, archaeologists have digitally modelled the sound of a conch-shell trumpet being sounded at a great house in relation to other features in the landscape. Soundshed Analysis calculates the distance a sound can travel from a point, taking into account both the type of sound and environmental conditions such as elevation and ambient noise.

“Chaco Canyon is surrounded by over one hundred understudied great house communities”, says lead author Professor Ruth Van Dyke from Binghamton University. “We sought to determine if extra-canyon great house communities demonstrated relationships similar to Chaco Canyon between landscape, community layout, and sound.”

In this case, the team modelled the sound of a conch from great houses at five Chacoan communities to determine whether it would reach all habitation sites within the community.

They found that if somebody blew a conch-shell trumpet from the great house at the centre of all five Chacoan communities, the sound would have reached almost all of the surrounding settlements.

This suggests that ancient Puebloans may have managed their land-use and community structures around the sound of trumpets. The sound was potentially used to signal communal activities, such as religious ceremonies.

“This is not unlike the idea of a medieval church bell calling a community to mass”, states Professor Van Dyke.

It also indicates how Chacoan heritage sites should be managed going forward.

“Soundscapes were meaningful dimensions of past experiences, landscapes, and environments and are important facets of social interaction in the ancient world,” observes Professor Van Dyke. “Management of archaeological and heritage sites should incorporate consideration of the auditory environment.”

Archaeologists discover 7000-year-old Neolithic mega-site

Archaeologists have discovered a 7000-year-old Neolithic mega-site near the village of Jarkovac in Serbia.

The discovery was made by a team from the Cluster of Excellence ROOTS, an initiative launched by several research institutions from across academia.

In a press statement announced by the Christian-Albrechts-Universität zu Kiel (CAU), a geophysical study has led to the discovery of a 13-hectare settlement with defensive ditches near the Tamiš River in Serbia’s Vojvodina province.

Based on the objects found in situ, the settlement is associated with the Vinča culture (also known as Turdaș culture), a Neolithic people that lived in Southeast Europe between 5400 to 4500 BC.

Named for its type site, Vinča-Belo Brdo (a large tell settlement in Belgrade), the culture is most known for constructing mega-site settlements, many of which were considerably larger than most other contemporary culture settlements in Europe.

ROOTS doctoral student and co-team leader Fynn Wilkes, said: “A settlement of this size is spectacular. The geophysical data also gives us a clear idea of the structure of the site 7000 years ago.”

Black angular anomalies apparent in the geophysics indicate a large number of burnt houses, suggesting that the settlement may have been abandoned or destroyed during conflict.

Archaeological evidence from other Vinča sites have led archaeologists to speculate that intergroup competition, conflict, and likely violence might have been a characteristic of the region during the Neolithic period.

Also uncovered are material traces of the Banat culture (5400-4400 BC), a regional people that emerged in the Banat area of the Pannonian Basin. “This is also remarkable, as only a few settlements with material from the Banat culture are known from what is now Serbia,” added Fynn Wilkes.

During the same research campaign, the team investigated several Late Neolithic circular features in Hungary together with partners from the Janus Pannonius Museum in Pécs. These so-called “rondels” are attributed to the Lengyel culture (5000/4900-4500/4400 BC).
