Novaya Zemlya largest number of fjords in the Russian Federation. Novaya Zemlya separates the Barents Sea from the Kara Sea. The total area is about . The highest mountain is located on the Northern island and is 1,547 meters (5,075 ft) high. Compared to other regions that were under large ice sheets during the last glacial period, Novaya Zemlya shows relatively little isostatic rebound. Possibly this is indebted to a counter-effect created by the growth of glaciers during the last few thousand years. The ecology of Novaya Zemlya is influenced by its severe climate, but the region nevertheless supports a diversity of
North Asia Urals, covering the northern two thirds of the Ob Basin and extending onto the Angara Shield between the Yenisei River and the Lena River. There are legacies of mountain glaciation to be found on the east Siberian mountains, on the mountains of the Kamchatka Peninsula, on the Altai, on Tian Shan, and on other small areas of mountains, ice caps remain on the islands of Severnaya Zemlya and Novaya Zemlya, and several Central Asian mountains still have individual glaciers. North Asia itself has permafrost, ranging in depths from 30 to 600 metres and covering an area of 9.6 million km².
