New Siberian Islands Islands (228 km²) lie to the north-east of Novaya Sibir. The New Siberian Islands are low-lying. Their highest point is located on Bennett island, with an elevation of 426 m. The New Siberian Islands once formed major hills within the Great Arctic Plain that covered the northern part of Late Pleistocene "Beringia" between Siberia and Alaska during the Last Glacial Maximum (Late Weichselian Epoch). These islands represent the remains of about 1.6 million square kilometers of the formerly subaerial Great Arctic Plain that now lies submerged below parts of the Arctic Ocean, East Siberian Sea, and Laptev Sea.

The total area of the islands is only 80 km. Some islands mostly consist of sand and ice and gradually erode. The total catchment area is 1,342,000 km. Among the rivers flowing into the East Siberian Sea, the Indigirka, Alazeya, Uyandina, Chukochya, Kolyma, Rauchua, Chaun, and Pegtymel are the most important. Only a few rivers are navigable.
