The Dropa Stones: Extraterrestrial Discs or Simple Chinese Rock?

Published on May 17, 2026 | Translated from Spanish

In the remote region of Bayan Kara Ula, China, supposed stone discs with spiral grooves were discovered. According to legend, these 12,000-year-old objects contain a message: the forced landing of an extraterrestrial spacecraft. The story is as fascinating as it is dubious, blending archaeology, science fiction, and a mystery that still divides researchers.

Ancient stone discs with spiral grooves being examined by archaeologists in a dimly lit cave, one disc partially embedded in rocky soil, a researcher holding a magnifying glass over the spiral patterns while another uses a portable XRF scanner to analyze mineral composition, dust particles floating in beams of natural light from a cave opening, stone tools and brushes on a portable workstation, cinematic photorealistic style, dramatic chiaroscuro lighting, ultra-detailed stone texture with eroded spiral carvings, mysterious atmosphere, technical archaeological documentation

The technical enigma of the grooves and their possible engraving 🛸

The discs, between 20 and 30 centimeters in diameter, feature fine grooves that, when analyzed, would reveal an unusual vibration frequency. Some researchers suggest the engraving was made with high-precision tools, impossible for the era. However, there is no conclusive evidence that these grooves contain a code or writing. The technology needed to create them, if real, would be advanced, but the lack of rigorous study leaves everything in the realm of speculation.

The spacecraft that landed in the archive of the unusual 👽

If extraterrestrials made an emergency landing 12,000 years ago, they surely chose the worst place on the planet to ask for help. Instead of a repair manual, they left some discs that look more like wall decorations than an interstellar message. Today, the theory lives on online, where anyone can sell you a stone with grooves and call it alien evidence. Let everyone draw their own conclusions.
