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.
