Which Russian peninsula lies between the Gulf of Ob and the Taz Estuary?

The Russian peninsula that lies between the Gulf of Ob and the Taz Estuary is the Gyda Peninsula.

Also called the Gydan Peninsula, it is a vast geographical feature on Siberia’s Kara Sea coast within the Yamal-Nenets Autonomous District. It is roughly 400 kilometers long and 360 kilometers wide. More precisely, the peninsula lies between the estuaries of the Ob and Yenisei Rivers, while its southwestern corner is limited by the Taz Estuary.

The name comes from the Gyda River, which flows across the peninsula. The landscape is mostly flat, cold, and sparsely populated, with numerous lakes and rivers. Permafrost and tundra dominate the ground, reflecting the region’s Arctic climate.

Its coastline includes several projecting subpeninsulas. The Mamonta Peninsula lies between Khalmyer Bay and Yuratski Bay, while the narrower Yavay Peninsula reaches toward the Gulf of Ob. Across the Taz Estuary is the Yamal Peninsula, a common source of confusion. The Taymyr Peninsula is much farther east.
