Yuryung-Tumus – a peninsula, serving as the border of the Nordvik Bay of the Laptev Sea from the west and juts out into the eastern channel, thus narrowing the latter to 25 km. It represents an undulating elevation, covered by tundra. The Solyanaya Sopka elevation (Tustakh, 125 m high) is located separately in the northeastern part of the peninsula. The eastern shores of the peninsula are almost steep cliffs above the water, whereas the northern and southern shores are sloping. A long low-lying spit runs out to the south from the southern shore of the peninsula, with a small bay in the west of it.
