Abstract.

The subject of this study is the Wrangel Island - the island of polar bears (local name - "Umkilir"). There is no indigenous population as such; the area is 7,600 km², out of which 4,700 km² is occupied by mountains in its central part; the highest point is 1,096 m (the Soviet Mountain). The object of this research is the polar landscapes that develop in xerocryotic environment and are notable for the unique appearance and arrangement. The goal and objectives consist in cognizing the nature of the regional climatic morphogenesis and characteristics of the organization (structure and functionality) of geosystems that possess augmented stability in typical environments of landscape genesis and are extremely sensitive to the effects of anomalous factors and processes. The materials and methods contain the data from the author’s permafrost-geomorphological research in Chukotka (1957-1959; 1971-1972), as well as accessible literary sources. The conclusion is made that the current development of Wrangel island’s terrain is defined and controlled primarily by the specific polar climate (directed continentalization of natural conditions; small amount of solid precipitation; high "wind tension" in winter, when snow is intensively blown into the sea; etc.). This results in the absence of the active loci of glaciation. It is determines that the development of morphogenesis on the island proceeds along the path of persistent displacement of nivation processes by constantly expanding and already prevalent cryogenic processes. Such trend of landscape development will continue for the near future.

Keywords: types of climomorphogenesis, development, cryogenic forms, climate, surface arrangement, polar landscapes, discovery, Wrangel Island, continentalization, nature reserve
