Mount Kosvinsky Kamen, Kosvinsky Mountain, Kosvinski Mountain, Kosvinsky Rock or Rostesnoy Rock (Russian: Косвинский камень, Косьвинский камень, Ростесной камень) is a mountain in the northern Urals, Sverdlovsk Oblast, Russia.
The Great Soviet Encyclopedia describes Kosvinsky Rock as "mountain massif" of height 1,519 m. Its constitution is pyroxenites and dunites of lower and middle Paleozoic era. The slopes are covered with conifers with some birch up to 900–1000 m, with alpine tundra above.
According to a 1 April 1997 article in the Washington Times, a CIA report claimed that there were construction works for a "nuclear-survivable, strategic command post at Kosvinsky Mountain". It was designed to resist US earth penetrating weapons and serves a similar role as the American Cheyenne Mountain Complex. The timing of the Kosvinsky completion date is regarded as one explanation for US interest in a new nuclear bunker buster and the declaration of the deployment of the B61 Mod 11 in 1997: Kosvinsky is protected by about 1,000 feet (300 m) of granite.
