Turan Depression

It is one of the largest expanses of sand in the world,[2] covering an area of around 3 million km2.

[3][failed verification] On average, the region receives less than 15 inches (380 mm) of rainfall per year.

The Karakum desert lies at the southern portion of the Turan Lowlands.

Vpadina Akchanaya in Turkmenistan is 267 feet (81 meters) below sea level.
