Here, we present the time variations of speciﬁc surface area and density of these crystals. Using the detailed snow model Crocus, we conclude that these crystals were very likely due to the nighttime formation of surface hoar crystals and to the day- discomfort with using tampons word

"Depth hoar, also called sugar snow or temperature gradient snow (or TG snow), are large snow-crystals occurring at the base of a snowpack that form when uprising water vapor deposits, or desublimates, onto existing snow crystals.

In other words, the moisture in the air skips the droplet stage and goes straight to crystallizing, similar to dew but when temperatures are below freezing. Hoar frost derives from the old English word “hoary,” meaning getting on in age.
