like a weird accident at a glass factory

Over the weekend we had warm weather and a lot of rain, and the area by my local river flooded. Just a few weeks earlier I was out snow shoeing by the river, now the area is accessible only to ducks. We've had a bit of cold weather, and the surface of the water froze to a thickness of a few millimeters. Now the water has partly drained away, leaving the layer of cracked ice suspended in the air by the tree trunks it froze around, some centimeters above the ground in many places. Much of it is thin and smooth enough to be semi transparent, and in a few places very thin clear ice sheets can be found. It's like a weird accident at a glass factory that somehow left the adjacent forest floor glazed.
