I don't understand what the stopped clock is supposed to signify. It's a device that show the current time except off by a bit—the number of large changes in the ice flow? like my microwave?

There's a yearly lottery pool based on who guesses closest to the time when the Nenana ice jam breaks up. The tripod falling over signifies when the river's moving.
