The archeologists were surprised at the specific drawings they found.
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.
Among these panels were spiral carvings up to one meter (3.3 feet) in diameter.

These, like most glyphs found in the area, were carved in the 12th or 13th century.
The Ancestral Pueblo spirals are circular like the famousMayan calendars, although the paper does not suggest any connection.
These discoveries forced us to adjust our knowledge about this area.
