One of the most amazing, beautiful and popular places in Altai. A geyser (blue, silver) lake with thermal springs, which periodically eject blue clay and silt from the ground, as a result of which the pattern on the surface is always unique and often changes. A similar thing is found in Kamchatka, Iceland and in Yellowstone Park, but there are usually powerful springs, but such a "quiet geyser" is a rarity.
