Sannikov Land
In 1886, a Baltic German explorer in Russian service, Baron Eduard von Toll, reported observing the elusive land during an expedition to the New Siberian Islands. In August 1901, during the Russian Polar Expedition, also led by Toll, the Russian Arctic ship "Zarya" headed across the Laptev Sea, searching for the legendary Sannikov Land. It was soon blocked by floating pack ice in the New Siberian Islands. Attempts to reach Sannikov Land, deemed to be beyond the De Long Islands, continued in 1902 while the "Zarya" was trapped in fast ice. In November, Toll and three companions left the "Zarya" and travelled south on loose ice floes, away from Bennett Island, and vanished forever.
