Reading the Scrabble Dictionary: Week 31

More about pogonip, or ice fog, because I found it interesting: it comes from Shoshone paγi̵nappi̵h, meaning, unsurprisingly, "cloud." American settlers in the early days called it the "white death," because they thought the ice crystals would kill them if it entered their lungs. Humidity has to be around 100% as the temperature drops below freezing for the ice crystals to form in the air and start to settle on things.
