Island Bar Ice Gyre

with thanks to Steve Armstrong & friends
Russ Henderson took this picture up the main Salmon River between Riggins and French Creek on February 8, 2010. Russ is working on a road project up there. The circle is turning clockwise from the current flowing downstream from the right. By the next day, it had worn the ice hook off to the left and had gone down stream and broken up. It must have been at least one hundred feet in diameter.

wait did someone cut this or is it natural? Explanation please?
That is amazing, I have never seen another thing like it. Nature is cool.
I’ve heard rumors about these things. Thanks for showing us. I’ll never see the Salmon the same way again.
wow. thats beautiful.
