Excellent link. Also good to see that YouTube are now often giving the option of using higher resolution for their vids. Cheers, Pip.

Lived in California for a whille and went to Yosemite a couple of times but, of course, not in winter. Pretty spectacular place. Might give it a try sometime one winter.

Awesome - thanks empip.

I wonder why it's called Frazil, is it a combination of fragile and freeze do you think?

Frazil Ice

an accumulation of loose, spongy ice within a body of water (deep frazil ice) or on its surface (surface frazil ice). Frazil ice forms from tiny crystals of deep ice (intermediate and bottom ice) and from grease ice and slush. It occurs before the freeze-up when water is supercooled below 0°C, primarily on mountain rivers and rivers with rapids, below polynyas and the lower pools of hydro-engineering complexes, and, occasionally, on lowland rivers and lakes.

Frazil ice, carried downstream by the current, covers large areas and dams up the channel, causing ice jams. It also considerably impedes the operation of hydro-engineering structures by clogging up the filters of water intakes and the aperture grills at hydro-electrical power plants.
