Singing dune

The wonderful phenomenon of nature is the Akkum-Kalkan sands, which was called „The Singing Barchan“. Sands, which in dry and windy weather sound like a highly flying jet plane. The power of sound is such that it spreads over many kilometers in the district. „Singing barkhan“ is located in the natural park „Altyn Emel“, between the two ridges Kysty – Kalkan and Ulken – Kalkan.

Barhan was formed as a result of blowing sand from the banks of the Ili River. A strong wind blows in this unit of the Ili river valley (between the Kalkans and the Boguty and Sogety mountains), which raises clouds of sand dust from the river banks. At the Big and Small Kalkans, standing at a slight angle to each other, the wind meets barrier and, wanes and leaves sand. For many millennium rose sand mountain 150 meters high, 3 km long in the depth of the Ili Valley. The barkhan stays fixed for several millennium, in despite of  fluctuation of sand and strong winds.

In strong winds, the barkhan begins to sound. The sound can be caused by quickly escaping or slipping in dry weather from the top of the barkhan. From the barkhan opens up a beautiful view of the surrounding locality. In the south you can see the glittering ribbon of the Ili River. On the horizon, in the haze, you can see the violet mountains of Sogety and Boguty. In the east and west, like the gates of a huge fortress, rise the Ulken-Kalkan and Kysty-Kalkan mountains. In the north, beyond the vast plain, there are a ridge of spurs of the Dzhungar Alatau, Mount Matai and Altyn-Emel.
