“The transition was extremely difficult. The path lay through the rows of huge, menacingly reared manes of dunes. Their crests, on which our camels walked cautiously, plummeted into the gaps of deep "uevs" - blowing hollows. On the bottom of these hollows lying deep below us, the wind whirled whirlwinds of blackish sand sparkling with sparkles of mica.
Ruins were drowned in the sea of ​​dunes - they were not visible either from behind or in front, but our guide confidently led us along a winding path, now skirting the "ui", then climbing the sandy slopes. And suddenly, from the crest of one of the dunes, a wide area of ​​takyrs, covered with a scattering of scarlet-red shards, suddenly opened in front of us.
Above the takyrs, the bizarre outlines of the ruins of a strange fortress rose, unlike anything we had seen so far. The destination of our journey was still far away."
