The Russian Discoveries, from the Maps Published by the Imperial Academy of St. Petersburg

This map was one of the most popular  to disseminate the discoveries of Vitus Bering and his associate Aleksei Chirikov along the upper Pacific coastline of North America, which had first been documented in a map issued by the Imperial Academy of Sciences in St. Petersburg (The explorations had been funded by the Tsar Peter the Great of Russia.) This map makes it clear how little was known about the Pacific Coastline of North America, but still provided the best delineation prior to the discoveries of Captain Cook.
