Archaeologists discovered ancient hearths and green mineral fragments in a high-altitude cave. This suggests that people repeatedly visited this remote location over 2,000 years, challenging our understanding of prehistoric communities.

High up in the eastern Pyrenees, archaeologists found evidence that changes how we think about how prehistoric people used mountain landscapes. A cave at an altitude of over 7,300 feet contains many ancient hearths filled with fragments of green mineral. This could mean that early copper mining activities took place here. The discoveries suggest that people visited this remote location repeatedly over a period of roughly 2,000 years. This challenges the long-held idea that prehistoric communities only briefly passed through high-altitude environments.

Researchers also found a child's finger bone and baby tooth, which raises the possibility that the cave may have been used as a burial site. The team has been studying the site since 2021 and has uncovered four distinct layers of human activity. The most recent layer was relatively thin and contained artifacts from historical periods.

The deepest and oldest layer only had charcoal fragments, dated to around 6,000 years ago. The second and third layers were more significant. Researchers found 23 hearths containing large numbers of crushed and burned green mineral fragments. If confirmed, this evidence could indicate that the cave was used as a surprisingly early high-altitude mining camp.

The hearths often overlapped each other, showing that the same area was reused repeatedly. At the same time, the individual hearths remained distinct, indicating that the visits were separated by substantial periods of time rather than representing a single continuous occupation.

Why It Matters

This discovery matters because it shows that prehistoric people were capable of complex activities like mining in high-altitude environments. This challenges our previous understanding and can help us better understand how ancient communities lived and adapted to their surroundings.
