Pigeon grotto (Orenburg region)

The Pigeon Grotto, located on the Kyzladyr Karst Field, is certainly one of the most famous sinkholes in the region. Like many other sinkholes in the karst field, the Pigeon Grotto is formed under the influence of rainwater, frost and various geological processes.

Inside the Pigeon Grotto sinkhole there is a small lake, probably fed by groundwater. A huge block of stone, consisting mainly of gypsum rocks, rises above the lake. This place is frequented by various species of birds who come here probably to drink water. It is because of this that the grotto got its name - Pigeon.
