The narrow strait between Taymyr island and the Siberian coast is called Proliv Taymyrskiy It is about 3 km (1.9 mi) wide on average.

Geologically all these coastal islands are a continuation of the Nordenskiöld Archipelago which lies further north.

[3] Taymyr Island belongs to the Krasnoyarsk Krai administrative division of Russia and is part of the Great Arctic State Nature Reserve – the largest nature reserve of Russia and one of the biggest in the world.

[4] In October 1900, during Baron Eduard von Toll’s last expedition, winter quarters for ship Zarya were set at Nablyudeniy Island and a scientific station was built there.

This is a small granite island southwest of Taymyr Island, located in a bay that Baron Toll named Bukhta Kolin Archera (Colin Archer Bay), after the shipyard where Zarya had been built.
