Hoar frost, aka frozen fog.

Dangerous shit in the mountains. When it builds on a snowpack it’s called surface hoar…then new snow falls on it and it becomes depth hoar - a weak layer (just a centimeter thick is enough) on which the new snow rests. Then, with the right trigger, that whole slab falls.
