Cape Zhygylgan is one of the main attractions of the Tupkaragan peninsula. Its name translates from Kazakh as "fallen earth". The name is very suitable for the cape, because it is a huge basin littered with boulders. Often the cape is called a "failure". Some boulders on the bottom of Zhygylgan reach the size of a small house.
In some places, the depth of the sinkhole reaches 200 meters, the shape of the depression is elliptical, and the diameter is about 4 km. The circumference of the bowl is 12 km. Because of the chaotically scattered stones, it seems that a strong earthquake has recently occurred. The failure is such an extraordinary sight that you can even shoot great movies about the apocalypse here.
Scientists have two hypotheses about the origin of the cape. Proponents of the first theory believe that the ground collapsed as a result of the displacement of tectonic plates. And according to the second version, the sea washed out the karst cavities located underground, which led to the collapse of the rocks.
Another interesting version is the fall of a meteorite, but the presence of cosmic rocks was not found.
Not far from the cliff is the "dead" lake Kozdikara. A rare sight: a large azure spot against the background of yellow sands and dry saxaul. From some angles, the reservoir takes the shape of a heart. The history of the reservoir is not known for certain, but there is a legend that the lake is so deep that if a ram falls into it, then after a while it will end up in the Caspian Sea.
