Polish Team Discovers 3rd-Century Astronomical Insights in Colorado Petroglyphs

The vast and rugged terrain of the Mesa Verde plateau, located on the border between Colorado and Utah, has long been an archaeological treasure trove. However, recent discoveries have brought to light an incredible aspect of this landscape: a network of ancient petroglyphs dating back to the 3rd century CE. Led by Professor Radosław Palonka from Jagiellonian University in Kraków, Poland, a team of archaeologists has uncovered these markings, revealing previously unknown details about the ancient Pueblo culture and their sophisticated understanding of astronomy.

A New Understanding of Pueblo History

The Castle Rock Pueblo settlement complex has been the focus of extensive archaeological exploration for over a decade. Situated in the higher and less accessible areas of Sand Canyon, Graveyard Canyon, and Rock Creek Canyon, this region was once home to the Pueblo people who thrived for nearly 3,000 years. The recent discovery of petroglyphs, some dating back to the Basketmaker Era of the 3rd century CE, provides a glimpse into the lives of these early inhabitants.

The findings challenge long-held assumptions about the population size and societal complexity of the Pueblo community. According to Professor Palonka, the petroglyphs reveal a previously unrecognized aspect of settlement patterns and cultural practices. The carvings indicate that this region was not only a hub of daily life but also a center for astronomical observations and ceremonial activities.

The petroglyphs found in the Castle Rock Pueblo area span several centuries, showcasing the evolving artistic and cultural expressions of the region’s inhabitants. The majority of the carvings, originating from the 12th and 13th centuries, depict geometric figures, spirals, and scenes of shamans, warriors, and hunting. These images reflect the community’s deep connection to the natural world and their reliance on hunting for survival.

Petroglyphs from the 15th to 17th centuries, influenced by the Ute tribe, include large narrative hunting scenes with horses—an addition made possible by the Spanish conquest. These carvings highlight the intercultural exchanges that shaped the history of the region.

A standout feature of this project is the collaboration with Native American groups, including the Hopi and Ute tribes. Tribal archaeologists like Rebecca Hammond have played an essential role in interpreting the iconography and understanding the cultural significance of the carvings. This partnership underscores the importance of engaging with local communities to preserve and interpret indigenous heritage.

Astronomical Insights and Technological Advances

Among the most intriguing discoveries are spirals up to one meter in diameter, which researchers believe were used for astronomical purposes. These petroglyphs align with significant solar events such as solstices and equinoxes, indicating that the Pueblo people had a sophisticated understanding of celestial patterns. This finding reshapes our understanding of their religious practices, suggesting a strong connection between their spirituality and the cosmos.

To further enhance their research, the team collaborated with the University of Houston to employ LiDAR (Light Detection and Ranging) technology. Using drones and helicopters, researchers created precise 3D maps of the canyons. This innovative approach has already led to the identification of previously unknown sites and is expected to yield even more significant discoveries in the future.

Preserving a Rich Cultural Heritage

The extensive rock panels surrounding the mesa plateau stretch up to four kilometers, offering a wealth of information about the ancient Pueblo culture. To ensure that these findings are preserved for future generations, the Polish team plans to record video interviews with tribal elders. These interviews will be part of a permanent multimedia exhibit at the Canyons of the Ancients Visitor Center and Museum, providing visitors with an immersive understanding of the region’s history.

Professor Palonka emphasizes that these discoveries dramatically alter our perception of settlement patterns in the Mesa Verde region. The collaboration between international researchers and Native American communities not only sheds light on the advanced achievements of ancient societies but also fosters a deeper appreciation for their cultural richness.

Conclusion

The uncovering of 3rd-century petroglyphs in the Castle Rock Pueblo settlement is a testament to the ingenuity and resilience of the ancient Pueblo people. These carvings reveal a society deeply connected to the natural world, with a remarkable understanding of astronomy and a rich cultural heritage that continues to inspire. As researchers and Native American communities work together to preserve and interpret these findings, the story of the Pueblo people is being rewritten, offering new insights into the complexities of North America’s indigenous history.
