In Yosemite Nature Notes – Episode 9 – Frazil Ice (video below), you see the shifting, natural melting process of frazil ice produced by Yosemite Falls. The water freezes on its descent from the river down to the base of the falls, forming something similar to a giant snow cone. This “frazil ice”, small crystals of frozen mist, then mixes with liquid water and snow to form amazing and interesting patterns downstream.

Makes you want to visit Yosemite in the spring, doesn’t it?
