only from Lütke's own work but also from various previously unpublished Russian sources. Even though there were errors and delays in the publication that didn't satisfy the author, Lütke's work is a valuable source of information on the evolution of geographic knowledge of Alaska and the Bering Sea. When W. H. Dall published an index for the book, Lütke's name was given as "Lutke", which reflects the spelling under which the book was published in Paris. Certain geographic features of the Alaskan coast, like the Walrus and Kritskoi Islands, Kudobin Islands and numerous other features in the Aleutians, were named by Count Lütke in the maps that were subsequently published. The landhead now named Cape Lutke in Alaska was named after this Russian explorer by the Imperial Russian Hydrographic Service in 1847. The Litke Deep is named in his honour.
