5,000‑year‑old tribal earth ovens found in Washington State
A joint project involving the Kalispel Tribe and archaeologists from Washington State University (WSU) has led to the discovery of 5,000‑year‑old earth ovens near Newport in Washington State, United States.
The ovens were found on land purchased by the Kalispel Tribe to accommodate for the construction of new housing near the tribal reservation.
A team of professional archaeologists and fourth-year students from WSU is currently working to delineate the features of the ovens and investigate any potential changes in their size and shape over time.
“As a Tribe, we’ve never shared this kind of historical excavation experience with the public,” said Kalispel Tribal elder Shirley Blackbear. “But I think it is important for non-Natives to learn and understand more about our Tribe. Our history and traditions are very rich and important to us. Cooking techniques have been passed down from generation to generation.”
Radiocarbon dating of the ovens suggests that they are 5,000‑years‑old, with the oven contents being sent to WSU labs in the hope of finding organic remains that might indicate the diet and food processing techniques of tribal ancestors living on the banks of the Pend Oreille River.
One of the main food types the researchers hope to learn more about is camas, a small flowering plant with roots that can be cooked fresh or ground into flour for baking over several days. While the Kalispel Tribe has preserved the tradition of baking camas bread by passing it down from generation to generation, not much is known about the oven technology they used before 3,000 years ago.
Professor Shannon Tushingham from WSU said: “Earth ovens have been excavated in this area before, but now in 2023 we have all these wonderful new technologies that give us the ability to better determine what types of food were being eaten and how they were prepared.”

A study of archaeological sites in Winchester, England, has revealed that red squirrels served as a host for Mycobacterium leprae strains that caused leprosy in people.
Leprosy is one of the oldest recorded diseases in human history and is still prevalent to this day in Asia, Africa, and South America.
It has previously been suggested that the extensive trade of red squirrel fur, greatly valued during medieval times, could have contributed to the leprosy epidemic in medieval Europe.
The results of the study, published in the journal Current Biology, studied 25 human and 12 squirrel samples from two medieval sites in Winchester.
During this period, the city had strong connections to the fur trade and housed the leprosarium, a hospital that treated people with Hansen’s disease (leprosy) caused by Mycobacterium leprae bacteria.
Verena Schuenemann of the University of Basel in Switzerland, said: “With our genetic analysis we were able to identify red squirrels as the first ancient animal host of leprosy.”
The study found that the medieval red squirrel strains were more closely related to human strains in Winchester, rather than to modern squirrel strains from England – suggesting an independent circulation of Mycobacterium leprae strains.
“Our findings highlight the importance of involving archaeological material, in particular animal remains, into studying the long-term zoonotic potential of this disease, as only a direct comparison of ancient human and animal strains allows reconstructions of potential transmission events across time,” says Sarah Inskip of the University of Leicester, UK, a co-author on the study.

Archaeologists from the Uncovering Roman Carlisle project have discovered a rare lump of Tyrian purple at the grounds of the Carlisle Cricket Club in Carlisle, England.
The project is a community supported excavation by Wardell Armstrong, focusing on uncovering a Roman bath house found in 2017.
The bath house is located near the Roman fort of Uxelodunum (meaning “high fort”), also known as Petriana, in the Carlisle district of Stanwix.
Uxelodunum was constructed to control the territories west of present-day Carlisle and an important crossing on the River Eden. The fort was garrisoned by the Ala Petriana, a 1,000-strong cavalry unit, whose members were all granted Roman citizenship for valour on the field.
Previous excavations at the bath house have discovered colossal sandstone heads depicting Roman gods, in addition to engraved gems known as intaglios, figurines, animal bones, and imperial-stamped tiles.
During the latest season of excavations, archaeologists found a mysterious lump of a soft purple substance. The substance was tested by researchers from Newcastle University, revealing that it contained levels of Bromine and beeswax.
According to the researchers, the substance is Tyrian purple, a coloured dye associated with the Imperial Court in the Roman Empire. Tyrian purple is secreted by several species of predatory sea snails in the family Muricidae, rock snails originally known by the name Murex.
Frank Giecco, Technical Director at Wardell Armstrong, said: “For millennia, Tyrian Purple was the world’s most expensive and sought after colour. It’s presence in Carlisle combined with other evidence from the excavation all strengthens the hypothesis that the building was in some way associated with the Imperial Court of the Emperor Septimius Severus which was located in York and possibly relates to an Imperial visit to Carlisle.”
“It’s the only example we know of in Northern Europe – possibly the only example of a solid sample of the pigment in the form of unused paint pigment anywhere in the Roman Empire. Examples have been found of it in wall paintings (like in Pompeii) and some high status painted coffins from the Roman province of Egypt,” said Giecco.
