The Yenisei Gulf is a large and long estuary through which the lower Yenisei River flows into the Kara Sea. The Yenisei Gulf is formed by the river widening to an average of 50 km for up to 250 km in a roughly north-south direction, between a latitude of 70° 30' N in the area around Munguy settlement, north of Dudinka. The whole region of the lower Yenisei is bleak and sparsely inhabited, and the settlements are built on permafrost ground. There is no vegetation except for mosses, lichens and some grass. Coastal waters are habitats for beluga whales.
