Mount Lazarev (Гора Лазарева, "Gora Lazareva") is a massif on the northern portion of Yuzhny Island, Novaya Zemlya, in Russia.[2] It was used for many Soviet nuclear tests, starting with the first underground nuclear test on Novaya Zemlya, 18 September 1964, which may have resulted in tired mountain syndrome.
