For the Turkic peoples, Altai is a sacred place, the ancestral home of the Turks! For ecologists, this is a storehouse of biodiversity! For hydrologists, it is a basin for the formation of the runoff of the largest rivers in Asia. For tourists, this is a dream! For the state - a source of valuable minerals. And for local residents it is a home. This issue of Outdoor World is dedicated to Western Altai.
