We also include a map of the famous Valley of Geysers (South of Klyuchi). The other side of the sheet portrays a vast region from the Russian occupied island of Sakhalin and the Okhotsk Sea north to that portion of what we call the Arctic Ocean but is really a series of seas (this one being the East Siberian Sea) and west to the Lena River. The Trans Siberian railway west towards Moscow is shown, as well as connections into Mongolia and China.
