In addition to river valleys, ice is often formed in places removed from rivers (pound ice).
In winter, with severe freezing of the soil in certain places, its slow swelling and the formation of tubercles begin, inside of which there is ice or ice with water; Bugrs over time increase and nyavrrh or side form, from which soil water flows, which gives new layers of ice on the surface of the tubercles. In the spring and summer, after the ice of ice, ice tubers disappear. The height of these tubercles reaches 5, and the thickness of the ice above them over 3 m these ice forms ice fields of small width and significant length (up to several hundred meters), often fill up the structures standing in their way, are transplanted through the railway canvas with small embankments and score holes of artificial structures and underground buildings.
