Frazil? What the heck is Frazil? Strange Ice at Yosemite National Park
A giant slurpee! Check out this interesting mini-documentary from the National Park Service and the Yosemite Fund (via YosemiteBlog.com). Frazil ice accumulates around the base of Yosemite Falls in the spring and does strange things. In some of the scenes, the ice flows alike a'a lava, complete with flow levees and breakouts. The footage of ice falling off the cliffs is pretty spectacular as well. It is fun to listen to when wandering about the area.
