, permafrost is ground, including rock or (cryonic) soil, at or below the freezing point of water 0 °C (32 °F) for two or more years. Most permafrost is located in high latitudes (in and around the Arctic and Antarctic regions), but at lower latitudes alpine permafrost occurs at higher elevations. Ground ice is not always present, as may be in the case of non-porous bedrock, but it frequently occurs and it may be in amounts exceeding the potential hydraulic saturation of the ground material.
The name of the plateau in central Russia is the central Siberian plateau. It occupies an area of 600,000 square miles and is situated in Krasnoyarsk kray region , Sakha and in Irkutsk oblast province. It is bordered by the Yenisey River to the west and the North Siberan lowland to the north. To the east it is bordered by the Lena river .
The average elevation is 1,650 - 2,300 feet above sea level. Vegetation in the plateau varies from tundra in the north to steppe - grassland in the south.
