On 24 June 2025, a significant landslide destroyed the Houzihé Grand Bridge on the Xiarong Expressway in Guizhou, China. A truck driver had an extremely lucky escape when his vehicle was left dangling into the void.

The tragic landslide in Blatten gives me the excuse to tell you the story of how we found out Ice Ages existed. It's a cool story and the most important bit is rather similar to what's happening now.
