I wish that more National Parks took the time to create videos like the Yosemite Nature Notes Series.  This is a group of videos specifically about the natural beauty and wonder of the park.  Previously, we have featured one of these videos on rockfall in the Valley.

This particular video that we are posting today describes an interesting and beautiful phenomenon that takes place late in the winter and early in the spring every year.  This phenomenon is called frazil ice.
