Ob River and Snow Across West Siberian Plain, Russia54.2N 81.8E
The part of this image that appears uniformly white is part of the West Siberian Plain, in Russia. Much of the plain is poorly drained and consists of some of the world’s largest swamps and floodplains.
The large, parallel dark streaks across the snowy plain are raised bogs in areas of peatlands. As these bogs have an elevation that is higher than the rest of the plain, they are not covered in snow.
Visible along the edge of the plain and to the north is the Ob River. The river’s surface is also frozen and snow covered, lending it its white appearance.
