Close

The river flows north of the Arctic Circle, across territories of the Krasnoselkupsky District marked by permafrost and swamps.^[2][3]

The Tolka is one of the main tributaries of the Taz. It is formed in the Siberian Uvaly hills, at the confluence of rivers Ai-Emtoryogan and Pyantymyogan. In its upper course the river heads roughly westwards across the tundra. After a long stretch it bends and meanders in a northeastern direction. Finally, south of the shore of lake Lake Chyortovo (Lozil-To), it bends eastwards, meandering until it meets the left bank of the Taz 723 km (449 mi) from its mouth in the Taz Estuary of the Kara Sea.^[2][4][3]
