Study uses satellite imagery to identify over 1,000 Andean hillforts

Published

A new study, published in the journal Antiquity, uses satellite imagery to survey hillforts known as pukaras in the Andean highlands.

Pukaras, meaning fortress in both Quechua and Aymara, were predominantly built on natural barriers such as hills and ridges during the Late Intermediate Period (AD 1000–1450).

Previous studies suggest that the necessity for these fortified sites arose from social and environmental circumstances, precipitating a period of conflict during the LIP.

What remains unanswered is the full extent and intensity of pukaras construction and distribution, which in part is limited by the difficult terrain and large spatial coverage. In addition, details on their size, defensibility, and density of residential and non-residential occupation are vague due to a bias towards studying the large, densely occupied pukaras.

The study authors used the results of three complementary systematic satellite survey projects, supplemented with targeted ground-checking and previous field research to reveal new insights into the pukaras phenomenon.

The study area covered 151 103km2 of the southern Andean highlands and identified 1249 high-confidence pukaras in the satellite imagery.

According to the researchers: “Pukaras coded as non-residential are surprisingly frequent; they are present throughout the study region in only slightly smaller numbers (n = 567) than residential pukaras (n = 682).”

The results also indicate that pukaras are densely concentrated in places such as the Lake Titicaca Basin and the Colca Valley, but also in substantial concentrations in parts of the south-central Andes.

In contradiction to the accepted narrative of defence, pukaras were also found in extremely high-elevation zones and areas where defensible land forms are absent.

The authors conclude that the survey demonstrates significant variation in the density of pukaras, raising important questions about the underlying social, political, economic, geographic or environmental contexts that propelled pukara construction in some regions and deterred it in others.

Revolutionary war barracks discovered at Colonial Williamsburg

Published

Archaeologists excavating at Colonial Williamsburg have discovered a barracks for soldiers of the Continental Army during the American War of Independence.

Colonial Williamsburg is a living-history museum that forms part of the historic district in the city of Williamsburg, Virginia.

Williamsburg was the capital of the Virginia colony from 1699 until 1779, founded by English settlers during the Second Anglo-Powhatan War (1622–1632).

Tensions with England mounted over fundamental civil and economic rights for the colonists, resulting in the American Revolution and the American War of Independence.

Archaeologists excavating next to the museum’s visitor’s centre uncovered foundations of a barracks that could accommodate up to 2,000 soldiers from the Continental Army and up to 100 horses.

“We have horseshoes,” said Jack Gary, Colonial Williamsburg executive director of archaeology. “We also have this object here which is a snaffle bit, so it’s part of a horse bit that goes in the mouth to control the horse. And this object here is part of a curry comb for brushing down the horse’s coat.”

Excavations have so far unearthed only a small part of the complex, but experts suggest that it covered roughly three to four acres.

The barracks were known from Eighteenth-century maps and other historical documents, but until now, the exact location of where it existed within the colony interior was unknown.

According to the historical sources, the barracks were built between 1776 and 1777, and were later destroyed by fire in 1781 by soldiers of the British Army under the command of General Cornwallis.

Excavations also uncovered mid-1700 chimney bases, ceramics, gun flint, coins, musket balls, military buckles, and items of decorative jewellery worn by high-ranking officers as cufflinks.

An interesting discovery are examples of lead shot with indications of tooth-marks, suggesting that the soldiers chewed on the lead shot because it tasted sweet.

Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought

Archaeologists have found that Pleistocene hunter-gatherers settled in Cyprus thousands of years earlier than previously thought.

An analysis of the oldest archaeological sites on the island suggests that the first human occupation occurred between 14,257 and 13,182 years ago.

This analysis, published in the journal Proceedings of the National Academy of Sciences, used archaeological data, climate estimates, and demographic modelling.

The demographic modelling indicates that these early groups consisted of hundreds to thousands of people, who arrived in two to three main migration events over a period of only 100 years. Within just a few centuries, 11 generations – the population of Cypris had expanded to up 4,000 to 5000 inhabitants.

According to the study authors, these findings refute previous studies that suggested Mediterranean islands would have been unreachable and inhospitable for Pleistocene hunter-gatherer societies. “This settlement pattern implies organised planning and the use of advanced watercraft,” says Professor Bradshaw.

The climate estimates suggest that these early settlers arrived at a time during an increase in temperature and precipitation, also enabling an increase in environmental productivity that could sustain large hunter-gather populations.

Dr Moutsiou, said: “It has been argued that human dispersal to and settlement of Cyprus and other eastern Mediterranean islands is attributed to demographic pressures on the mainland after abrupt climatic change saw coastal areas inundated by post-glacial sea-level rise, forcing farming populations to move to new areas out of necessity rather than choice.”

Our research, based on more archaeological evidence and advanced modelling techniques, changes that”, adds Dr Moutsiou.

The research – “Demographic models predict end-Pleistocene arrival and rapid expansion of pre-agropastoralist humans in Cyprus” by Corey Bradshaw, Christian Reepmeyer, Frédérik Saltré, Athos Agapiou, Vasiliki Kassianidou, Stella Demesticha, Zomenia Zomeni, Miltiadis Polidorou and Theodora Moutsiou – has been published in the Proceedings of the National Academy of Sciences of the USA.
