Ice circle
Ice circles are conspicuous, round ice floes that can be several meters to several kilometers in diameter. Small ice circles a few meters in diameter sometimes turn. Structures several kilometers in size were observed on Lake Baikal by the Limnological Institute in Irkutsk . Rising natural gas is held responsible for their creation. When it is cold in slow-flowing rivers and lakes, they are circling ice disks .
