BISMARCK — When George Loegering saw a large spinning circle of ice in the Sheyenne River while out hunting with relatives, the retired engineer couldn't believe his eyes.

"At first I thought, no way! It was surreal," Loegering, 73, said Tuesday of the large ice disk he witnessed Saturday. "You looked at it and you thought, how did it do that?"

Then his engineering background kicked in. He calculated the disk's diameter to be about 55 feet, took photos and videos of it and then turned to the Internet for more information about what he, his brother-in-law and nephew had seen.

"It's not an unknown phenomenon, but it is relatively rare," said Loegering, who lives in rural Casselton, about 20 miles west of Fargo.

Allen Schlag, a National Weather Service hydrologist in Bismarck, and Greg Gust, a weather service meteorologist in Grand Forks, said a combination of cold, dense air last weekend and an eddy in the river likely caused the disk.

"It's actually quite beautiful," Schlag said.
