Siberian Forests

The forested lowlands west of the Yenisei form part of the vast Siberian taiga. Rivers such as the Ket and the Kas wind through poorly drained ground towards the Ob and Yenisei, while lakes and peatlands interrupt the coniferous forest. Travellers once crossed the divide between the two river systems by portage, carrying boats and goods through wooded and marshy terrain. The long winter freezes the waterways, followed by spring thaw and high water.
