kavkazblog: Sarykum is the largest dune not only in Russia, but throughout Eurasia, its height can reach 250 meters. It is located in Dagestan Nature Reserve near Makhachkala city. The uniqueness of the dune is that it is located not in the desert, it is surrounded by green steppe. Experts suppose that the sand was brought there by water more than ten thousand years ago, and the appearance of the dune was formed about four thousand years ago. -- source link
