Old man river now rolls in silence

Well, the Tanana River is completely glazed over with ice now, and it looks so... stagnant. I know that there is water flowing underneath, but it's startling to have such a starkly silent river after months of violence. A few months ago, there was the rushing, brown turbulence of flooding. One week ago there were flat ice shards floating down the river like jagged crystal lily pads. Yesterday there was the arresting contrast of the gentle rosy glow of the sunrise against the steady crunch of ice chunks beating together in a crazy cacophony. Today there is a completely covered surface, and silence.
