Ryn
The Ryn, or Naryn sands, stretch across the northern Caspian lowland between the Volga and the Ural. Dunes and sandy ridges alternate with hollows and patches of steppe pasture. In 1801 Sultan Bokei and families of the Lesser Zhuz were allowed to cross the Ural into the lands between the rivers. The Naryn sands became part of the pastures of the Inner Horde, whose herders also used the reed beds and floodplains nearer the Caspian coast.
