The first frame of the promotional film for the Beijing 2022 Winter Olympics was a snowflake, and the deputy who tells the story says it drifted out of a painted cave at Dundebulak in Altay. On that rock, she says, people carved skiing and hunting scenes more than ten thousand years ago, and the site is cited as evidence for the origin of skiing.
The claim is hers — Zhuo Ya·Baheti, a curator at the Altay regional museum — and the essay keeps it attributed. What can be checked is the image and its travel: a small painted panel in a cave has become a national symbol, while the rock itself stays where it was.
