Mount Kosvinsky Kamen, Kosvinsky Mountain, Kosvinski Mountain,[1] Kosvinsky Rock or Rostesnoy Rock (Russian: Косвинский камень, Косьвинский камень, Ростесной камень) is a mountain in the northern Urals, Sverdlovsk Oblast, Russia.[2] [3]
Its summit is bare of vegetation with an uneven rocky surface and small lakes fed by melting snow. The Kosva River flows from the mountain, hence the name.[3]
The Great Soviet Encyclopedia describes Kosvinsky Rock as "mountain massif" of height 1,519 m.[4] Its constitution is pyroxenites and dunites of lower and middle Paleozoic era. The slopes are covered with conifers with some birch up to 900–1,000 m, with alpine tundra above.[5]
According to Jane's Defence Weekly, a command post bunker was built near the mountain as of 1994.[6] 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 1000feet of granite.
US analysts believe that the command post of the Perimeter system is in the bunker under Kosvinsky Kamen mountain.[7] [8]
