Life at high altitudes is unforgiving. The thin air and ambiance manufacture breathing and different bodily functions sophisticated—especially for humans. On the opposite hand, a cave over 7,000 ft above sea level in the Pyrenees Mountains between France and Spain is forcing archaeologists to rethink how typically our prehistoric ancestors made spend of these heights.
A crew found a cave in Spain elephantine of hearths, jewellery, and human remains, indicating that folks might maybe presumably had been living at this incredibly high altitude so long as 5,500 years in the past. A baby’s finger bone and a infant tooth discovered among the rock also draw this cave might maybe presumably had been a burial dwelling. The cave and its findings are detailed in a peep published at the novel time in the journal Frontiers in Environmental Archaeology.
For many years, archeologists believed that top-mountain environments esteem these had been areas that prehistoric communities handiest passed thru every now and then. Cave 338 is 7,332 ft above sea level in Spain’s Núria Valley. The crew dug thru four distinct rock layers, with the oldest dating help 6,000 years in the past. The most most well-liked layer used to be thin, indicating that it used to be no longer typically weak.
But layers two and three had plenty of surprises. The crew found 23 hearths, all with beaten, burned inexperienced mineral fragments. The inexperienced fragments resemble malachite, a mineral that is filthy rich in copper. From these preliminary clues, the crew suspects that Cave 338 used to be a high-altitude mining camp between 3,000 and 5,500 years in the past.

“A bunch of these fragments are thermally altered, whereas different materials in the cave are no longer, which clearly suggests that fire carried out an vital role in their processing and that there used to be a deliberate intention behind it,” Dr. Julia Montes-Landa, a peep co-writer and archaeologist and archaeometallurgist at the University of Granada in Spain, stated in a press begin. “In different words, they weren’t burned by chance.”
The hearths also nick all the draw thru each and every different, indicating that the company to the cave reused it typically. Moreover they’re distinct, showing their visits had been separated by a ideal chunk of time.
In the third rock layer, the crew found a finger bone and a infant tooth belonging to as a minimum one child who died around the age of 11. This might maybe occasionally presumably imply that more human remains are buried deeper within the cave, but there might maybe be presently no longer sufficient proof to determine a motive behind loss of life or if the bone and tooth belong to the identical child.
On the opposite hand, two pendants found in the 2nd layer equipped more information about the likely remains. One pendant is made of a shell and the different a brown bear tooth and dates to around the 2nd millennium BCE.

“The shell pendant is interesting this potential that of it has parallels in different sites in Catalonia, which potential shared traditions or connections between different communities,” Dr. Carlos Tornero, a peep co-writer and zooarcheologist at the Catalan Institute of Human Paleoecology and Social Evolution, stated in a press begin. “The bear tooth pendant is distinguished much less in vogue. That can presumably point to something more particular or symbolic, presumably linked to the local ambiance.”
While Cave 338 used to be no longer a elephantine-time house, these that came here will must bear found their journeys up the mountain treasured sufficient to retain returning for thousands of years.
“We are in a position to’t hiss exactly how long folk stayed at any time when, however the repeated spend of the house and the density of remains suggest occupations that had been short to medium in duration, but happening again and again over long lessons of time,” Torneo added.
The crew soundless has quite rather a lot of questions about how and when humans weak the cave and hope to gain a definitive solution on the chemical composition of the mysterious inexperienced mineral during upcoming field work this summer.
