Archeologists have documented incredible spiral calendar rock carvings in the cliffs of the famous Mesa Verde region, carved by the Ancestral Pueblo people.

Across human history, time has been measured in different ways—by moon cycles, plants ripening, and saints days. What we know to be the modern year can be divided in any number of ways; however, tracking time has always been critical, no matter how it is measured. Societies developed innovative calendars for this human need. Archeologists working in the canyons along the Colorado-Utah border documented what they believe to be a previously unknown sort of spiral calendar, carved and used by the Ancestral Pueblo people. The discovery of these reliefs came after tips from local elders that something of interest could be found high above the iconic, visible dwelling houses set into the cliff sides.

The team is led by Polish archeologist Radosław Palonka of Jagiellonian University, whose doctoral work with American Professor Willian Lipe led to opportunities to research in the United States. The calendar relief was discovered near Castle Rock Pueblo in the Mesa Verde region. The village was populated in the 13th century by the Ancestral Pueblo people, who had roots in the four-corners area stretching back thousands of years. From the beginnings of cultivation to the invasion of colonizing Spaniards, the Ancestral Pueblo lived in the southwest, largely migrating away from Mesa Verde in the 13th century. They created impressive cliff dwellings, magnificent circular kivas for religious ceremonies, and cliff drawings.

The archeologists were surprised at the specific drawings they found. Palonka said in a statement, “I used to think that we studied this area thoroughly, conducting full-scale excavations, geophysical surveying and digitalization. Yet, I had some hints from older members of the local community that something more can be found in the higher, less accessible parts of the canyons. We wanted to verify this information, and what we found surpassed our wildest expectations. It turned out that about 800 meters above the cliff settlements there are a lot previously unknown petroglyphs. The huge rock panels stretch over 4 kilometers around the large plateau.”[…]
