The Russian explorer V. K. Arseniev received a hero's welcome when he returned to Moscow from the Far East in 1906, having mapped the unknown corner of Siberia just above what is now North Korea and just east of Manchuria.

Arseniev then wrote a remarkable memoir devoted to the Goldi trapper, Dersu, who saved his and his men's lives on more than one occasion while showing them the ways of the deep forest.
