Icecircles

Ice On The Missouri 2015-01-10 4

The end of the Missouri River, just before it blends into the Mississippi. At this time of year it's full of ice disks. This happens mostly in North America and Scandinavia. Eddies in slow moving rivers spin the water. Equal temperature on all sides lets the water freeze in rough circles. They spin downstream into the fast-flowing, clear Mississippi.

We see it here as well. I would love to travel up the length of the Missouri someday.

Yet, they look so innocent. Deadly if not having your wits about you. Can you say hyperthermia? I know you can.

Ice circles are specialized local knowledge from the Lou. We have never had them in the northern cities where I lived.

I love these ice circles. Thks for all the info about the confluence - the ice/no ice effect is quite striking!
