Breakup (2007) by Brian L. Frye; video, color, silent, 1.5 minutes.
Breakup is the shortest season in interior Alaska. All of the sudden, winter ends, the snow soaks into the tundra, and the ice on the river begins to crack. Everything is a muddy bog for a bit, perhaps a week or two. And then it's done, just as quick, the last bits of ice floating in the glacial silt.
