We saw this mesmerizing phenomenon on our river for the first time this winter. It was at our little rapids, where the water flows quickly over some rocks.

They are little hollow pillar-like structures. The water is flowing up through them and you can see it bubbling and gurgling at the top. It is almost like a small volcano. They look a bit like stalagmites coming up from the frozen river top.

It seems like, every winter, there is something new for us to observe at the river!

If anyone knows what this is called, I would love to hear it.
