Kazakhstan 🇰🇿, singing barkhan Aigaykum

The singing barkhan Baigakum (translated from Kazakh as "singing sands") is the main attraction of the Altyn-Emel National Park.

The singing dune is a mountain of pure quartz sand without vegetation, with a steep slope. When dry sand moves, the grains of sand rub against each other, which produces a long, loud sound similar to low singing. Therefore, the dune was called "Singing". Such a rare natural phenomenon is noted only in a few places in the world.
