Children are actually born with an innate appreciation for ice-flow indicators, they just need to be forcefully made to realize it.

@drewbrayshaw.bsky.social, CBC really covering all their bases with this one.

There are reports of yet another terrible landslide at the Rubaya coltan mining area in the Democratic Republic of Congo. As always, the losses are unclear, but may well exceed 100 people. www.bluewin.ch/en/news/land...

The 17 December 2024 Takhini River landslide and river-ice tsunami in Whitehorse, Yukon, Canada highlights the role of progressive failure in frozen materials. eos.org/thelandslide...

Here's an article I wrote on a novel landslide that generated a destructive river-ice tsunami on the Takhini River last winter. Definitely a hazard to consider in cold regions.
