Unfortunately I did not have a long lens at the moment that I saw what was more likely an actual rodent chewing coyote on a snow covered meadow. The real attraction of this last weekend, which I spent at a photographic field study in Yosemite Valley was the ice formations. Having had a particularly harsh cold snap, followed by warmer days and overnight freezes, the ice in the rives was quite special.
Here are a few images from those rivers and creeks.
