A closer look
Geologists love a good pedantic technicality, and winter weather is their absolute favorite loophole. To be classified as a mineral, a substance must be naturally occurring, inorganic, solid, have a definite chemical composition, and an ordered crystalline structure. Snow hits every single metric perfectly. Ice is a literal mineral, and snow is just a collection of ice crystals. This also means an avalanche is just a very cold, very fast rockslide, and building a snowman makes you an amateur mason.
