While shooting the photos of the Trumpeter Swans I showed in my last blog post I suddenly heard a crunching noise behind me, coming from the main channel of the river. A really huge ice floe had broken loose and started moving, grinding, and crashing against the rocks at the Potosi boat landing. We had a cold snap the night before and much of the Mississippi had frozen over again.
I like the crunching noise and hit the video button on the camera to capture the powerful movement of the river. Turn your speakers on loud, click the video below, and feel free to watch the little show.

This photo was shot later a few miles further south, giving you an idea how the ice got jammed above the lock and dam in Dubuque, IA, which is located but hardly visible at the horizon line.
