Siberian Hills

The Polousny Range rises along the southern edge of the Yana–Indigirka lowland, north of the Aby plain. Its main ridge runs roughly east to west between the headwaters of the Khroma and the Indigirka. Streams descend from these heights toward the Arctic lowlands, cutting valleys through the northern mountain country. Snow and prolonged cold dominate the ridges for much of the year.
