I was elated to see that the circle was still intact and spinning.
No Photoshop here. No human intervention, either.
A chunk of ice broke loose from the Snoqualmie River in Washington state on Saturday. The slow-moving current shaped the chunk into a perfect circle, according to our partners at KOMO.

Now for some science
This circle formed after the top layer of water froze, then got caught in a river eddy. It's not exactly very stable. If you threw a decent-size rock at the ice, it would fall through, meteorologist Allen Schlag told KOMO.
This isn't the first big all-natural ice circle. North Dakota's Sheyenne River had an ice circle way back in 2013.
