Hair ice, also called silk frost, is a type of ice formation that looks like silk and seems to only appear on woody, barkless materials on the ground. The ice structures tend to grow out of a small pore in the wood, sort of like hairs on the human head. Dr. James Carter has more on the phenomenon (and more photos too) on his site.

Maybe it’s just because I live in sunny Southern California and never actually see snow, but it truly fascinates me. Even if you’ve had your lifetime share of cold weather though, you’ll still probably love these photos of frost, snow and ice. Plus, if you actually read the text, you just might learn something new.
