Земля Санникова
In 1809–10 Yakov Sannikov and Matvei Gedenschtrom went to the New Siberian Islands on a cartographic expedition. Sannikov reported the sighting of a "new land" north of Kotelny in 1811. This became the myth of "Zemlya Sannikova" or "Sannikov Land". In 1886 Polar explorer and scientist Eduard Toll, during his first visit to the New Siberian Islands, thought that he had seen an unknown land north of Kotelny Island. He guessed that this was the so-called "Zemlya Sannikova".
