Finding Sannikov Land was the main goal of the Russian polar expedition, which left St. Petersburg in 1900 on the Zarya ship. However, in pursuit of this dream, Baron E.V. Toll and his companions went missing. Their search was led by the hydrologist of the expedition - a young naval lieutenant A.V. Kolchak, who managed to reach the place of the last stay of Tolya with the help of a whaleboat.
