The main arrays of belt hogs are located in the Altai.Their name is consonant with the names of the small rivers flowing through them -the Barnaulka, Kasmala, Burla, Kulundy.The longest is the Barnaul pine forest belt, which stretches for 550 km from the Ob River in the vicinity of Barnaul to the Irtysh River in the vicinity of Semey in Kazakhstan.Experts still argue about the age and origin of hogs and growing conditions.The most common version is that the belt forests were left after the last ice age, which was observed about 10,000 years ago.Then the territory between Ob and Irtysh was located between two huge glaciers.During the melting of glaciers, water flows carried masses of sand, which gradually accumulated in the bottoms of narrow and long hollows.Later, pine trees began to grow on the deposited sands.This is the secret of the unusual linear arrangement of these forests.Over the millennia, a unique landscape has developed: forests grow in the hollows, and steppes dominate the spaces between them.
