The islet permafrost

Look at the map: in the North Caucasus, near the resort town of Zheleznovodsk, at mount Razvalka that rises to 720 meters above sea level, is an islet of permafrost, which is unparalleled in the southern temperate latitudes. The layers of permafrost here reach a depth of 9 meters.

Razvalka is magmatic mountain in Pyatigorye, the Caucasian Mineral Waters. It is located 1.5 km north of the town of Zheleznovodsk, in the territory of the urban district of Zheleznovodsk. The upper part of the mountain is a steep rocky ridge length of 1 km and a relative height of 200 m, built of light gray beshtaunit. The southern half of the ridge sharply rising over the northern and resembles a lion's head, due to which in the 19th century, the mountain was called "Sleeping lion".

The islet permafrost covers an area of about 1 ha in the northern and eastern slopes of mount Razvalka at 620720 m altitude level.

It came here because of the cold air flow from fissures with temperatures ranging from -1 to +40 C, having (0,314%) of carbon dioxide, which for some unknown reason blowing from the bowels of the mountain. For this reason, even in deep cracks summer stored ice crystals. It is possible that in the depths of the mountain is still preserved relict permafrost, which arose in the era of the Pleistocene glaciation.

The islet permafrost has had its impact on the flora and fauna of the mountains. Interestingly, the vegetation on this island is fully consistent with the tundra zone, then you will not see anywhere else in Zheleznovodsk area. If most of the mount Razvalka covered with broad-leaved forest with islands mountain-meadow and rock vegetation, characteristic Beshtaugorsky woodland, at the island of permafrost formed an unusual mountain ash and birch elfin with the association of cold-loving plants such as raspberry, honeysuckle, alder, aspen, bird cherry.

The animals here are found snow vole and some insect species, found only in the Caucasus, in the highlands.

This same island permafrost is known in Romania, on the hillside Petroshul, near the city of Suceava.

Until now, all these mysterious phenomena have not received a scientific explanation.
