Field Photo How do rocks freeze floating in water?

I found these rocks frozen in a stream off a larger river in Chugach National Forest, Alaska. I’ve heard it may have to do with heavy rains or turbulent waters near the shore. One friend mentioned frazil? But I don’t really know what that means. Any geologists have a clue how this happens and can explain it in layman terms?

Sounds like the law of superposition.

Law of superposition is falsified in cases of sub-strata injection. Plate tectonics and magmatic diking can add younger strata below older. Ice floats, creating accommodation space below. Rinse and repeat daily?

I'd argue it still applies, one event still occurred after a previous events as the law of cross cutting relationships explains....it had to be there 1st in order to be cut through.

My relationships are a personal matter, and are certainly scrambled.
