Thanks for sharing @davepetley.bsky.social!

@theronfinley.bsky.social, Panya, Jan, and I were very fortunate to be able to get to the site to survey the impacts of the earthquake. I'm very grateful for how many "once in a lifetime" opportunities we get up here!

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. Thanks to the folks who gave me their thoughts and comments on the paper: Panya, Marten, Hig, and anonymous!
