Pur
The Pur is formed by the meeting of the Pyakupur and Aivasedapur, rivers descending from the Siberian Uvaly. It flows north through the low, waterlogged plain to the Taz Estuary, with forest and bogs along its upper course and forest-tundra farther north. Snowmelt feeds a great spring rise after the long winter freeze, spreading water across the river’s low banks.
