Beautiful Blue

This is a smal feature in a bay of Lake Constance on the oppositte side of the rhine dam, here in the most left layer where the path is near open water.

The ice breaks up from expansion, forming structures up to 30 or 40cm high and without much movement the bare eye can see.

I remember ice on flowing rivers with piling plates like this in much bigger scales, but not rivers the size we got here. The Argen and the Rhine upward the falls are very fast flowing, most others around Lake Constance are smal brooks in comparison, barely sufficient for canoeing most seasons between their dams.

The rivers with towering shelves that fold up whilst slowly flowing I saw in the USA where of course mostly deeper inland. I was most impressed at the Connection of Lake Huron and Lake Saint Claire with the big Black-backed Gulls diving in amongst that moving sculptures to dig out frozen fish parts and stuff. Also at Grafton where the Missouri and Missisippi meet and a lot of Bald Eagle have their winter homes, all scavenging together in the dangerous confluence ice mills.

Here we do not have birds brave as this, probaply for we rarely have moving and seriously high piling shelf ice every year. All we have is ice expanding on top of shringing water levels in the lake bays making those smal still objects.
