Olgon-Gorinskaya expedition of 2020: following the trail of the 1917-1918 expedition - on the 150th anniversary of V.K. Arsenyev's birth

The «Ways of Great Achievements» project has been for several years focused on scientific works by Vladimir Klavdievich Arsenyev, one of the leading Russian researchers of the Far East. A historical and ethnographic automobile expedition took place in February 19-24, 2020, on the route of the Arsenyev’s Olgon-Gorin expedition of 1917-1918, which had been the least studied of all his expeditions. However, that expedition was famous for the collected ethnographic material of great value about the population life style of that time, including the Yakuts, in the Amur Region.
