There is a fascinating phenomenon that can be seen in Yosemite creek in late winter or early spring; it is called "frazil ice".
Our recent visit was too early to see anything but a hint of what it may be like later in the year. It has its genesis in the build up of ice that forms along side the falls during the chilly nights.
When the sun hits the cliff the ice falls off and into the creek. You can glimpse a bit of it flowing here in the creek. It's not the ice clinging to the rocks but the slushy bits flowing in the creek. There was not much, not enough to impress.
The ice flowed down the creek until it was stopped by a log jamb. Had there been more water in the creek it would have kept going, down to the Merced River. When the creek is high and there is a lot of this frazil ice there's a river of slush, interesting to watch and dangerous to anyone who would walk out onto it thinking it a snow field.There is a great video of this Phenomenon produced by Yosemite National Park and the Yosemite Fund. You may have seen it, it has gone viral. I got the link from three different friends.
