History and origin of name
The Russian polar explorer Eduard Toll (1858–1902) was the first researcher to map the landscape between Anabar and western Popigai and the mountain range of the Prontschishchev ridge located a little east of Anabar Bay between Anabar and eastern Olenjok in 1893. In honor of the Russian explorer and polar explorer Vasily Prontschishchev (1702–1736), whose expedition reached the mountain ridge and who described it in 1735, he gave the small mountain its current name.
