Monument of nature (1964) near the village of Opolznevoy. In the western part of the Southshore, chaotically heaped limestone rocks and boulders, large sections of the slope, displaced from their original places as a result of landslides, are quite often encountered. The famous Kuchuk-Koysky landslide and the stone stream near the village of Opolznevoye convince of the grandeur of this kind of phenomena. A huge pile of Upper Jurassic limestone blocks was formed as a result of a large landslide that occurred at the end of the 17th century and was described by the famous naturalist P.S. Pallas.
Here is what the academician wrote about this phenomenon: “The collapse in Kuchuk-Koy occurred on February 10, 1786, when the surface of the earth began to crack and dip, and on the same day the river, on which two small mills stood, disappeared among these cracks. the following days, the formation of cracks continued, intensifying, and the frightened inhabitants of the nearest village abandoned their houses and left with all their livestock and property.Then the whole area ... cod and continued to collapse until February 28, forming a terrible abyss, among which one large and two smaller ridges of stronger rocks remained ... and the entire strip of land lying below moved into the sea and pushed its coast to a distance of 50 to 80 fathoms .. (i.e. 150-160 meters).
