No, the river just thawed in the middle of winter. This usually happens every spring, but apparently there was a thaw and the ice broke, and it all floated down in a heap. One of the speakers claims that this is the second time, that is, all this heap of ice, water, snow and trees is floating by, and the river is becoming shallow again. Geographically, it is relatively close to the border with China. But no one said what river it was.Was that a result of a broken dam????
This did not cause any particular damage, except for trees torn out along the edges, but people argue that being on the river at this time is dangerous. You can go fishing on the ice, and then suddenly in the middle of winter something like this suddenly arrives.
And in the spring this is quite common. The ice is melting, the snow is melting, there is a lot of water and it all flows, partially breaking the forest.
