History The range is located in a remote area and was unexplored until mid 19th century. Between 1849 and 1853, a large Russian military expedition led by Nikolai Khristoforovich Akhte operated in the Russian Far East. The German surveyor of the Russian service Ludwig Schwarz was assigned to it as an astronomer. Together with topographers Stepan Vasilievich Krutiv and Alexei Argunov, as well as geologist Nikolay Gavrilovich Meglitsky, the Yam-Alin range area was studied and topographically surveyed in detail. Based on their measurements, the first reliable map of Yam-Alin was drawn in 1851.Агте, Николай Христофорович - ИРКИПЕДИЯ
