Wyspy Czterech Gór (ang. Islands of Four Mountains) – grupa wysp wchodzących w skład łańcucha Aleutów (stan Alaska), położona między Andreanof Islands na zachodzie oraz Wyspami Lisimi na wschodzie. Ich łączna powierzchnia wynosi 545,596 km². Wyspy nie posiadają stałej ludności. Największe wyspy tego archipelagu to Yunaska i Chuginadak. Inne wyspy to: Amukta, Chagulak, Herbert, Carlisle, Uliaga i Kagamil.

Nazwę wyspom nadali w pierwszej połowie XIX wieku Rosjanie. W 1826 na mapie Sariczewa pojawiła się nazwa Четырехсопочные острова (czyli „Wyspy Czterech Wulkanów”), odnosząca się do czterech charakterystycznych szczytów wulkanicznych: Mount Cleveland, Mount Carlisle, Mount Kagamil i Mount Herbert. Nazwa aleucka to Unigun, co oznacza „miejsce narodzin wiatru”. Obecna angielska nazwa archipelagu oraz nazwy poszczególnych wysp zostały zebrane w 1894 podczas wyprawy USS Concord i opublikowane przez U.S. Navy Hydrography Office w 1895.

Flag of the United States.svg
The flag of Navassa Island is simply the United States flag. It does not have a "local" flag or "unofficial" flag; it is an uninhabited island. The version with a profile view was based on Flags of the World and as a fictional design has no status warranting a place on any Wiki. It was made up by a random person with no connection to the island, it has never flown on the island, and it has never received any sort of recognition or validation by any authority. The person quoted on that page has no authority to bestow a flag, "unofficial" or otherwise, on the island.

ISS-38 Islands of the Four Mountains.jpg
Islands of the Four Mountains are featured in this image photographed by an Expedition 38 crew member on the International Space Station.
  • Morning sunlight illuminates the southeast-facing slopes of the islands in the photograph. The islands, part of the Aleutian Island chain, are actually the upper slopes of volcanoes rising from the sea floor; Carlisle, Cleveland, Herbert, and Tana. Carlisle and Herbert volcanoes are distinct cones and form separate islands. Cleveland volcano and the Tana volcanic complex form the eastern and western ends respectively of Chuginadak Island; a cloud bank obscures the connecting land mass in this image. Cleveland volcano (peak elevation 1,730 meters above sea level) is one of the most active in the Aleutian chain, with its most recent activity–eruptions and lava flow emplacement–taking place in May of 2013.
  • The northernmost of the islands, Carlisle volcano's (peak elevation 1,620 meters above sea level) last confirmed eruption occurred in 1828, with unconfirmed reports of activity in 1987. Herbert volcano (peak elevation 1,280 meters above sea level) to the southwest displays a classic cone structure breached by a two-kilometer wide summit caldera (upper right), but there are no historical records of volcanic activity. The easternmost peak, Tana (1,170 meters above sea level) is a volcanic complex comprised of two east-west trending volcanoes and associated younger cinder cones; like Herbert volcano, there is no historical record of activity at Tana.
  • A layer of low clouds and/or fog obscures much of the lower elevations of the islands and the sea surface, but the clouds also indicate the general airflow pattern around and through the islands. Directly to the south-southeast of Cleveland volcano a Von Karman vortex "street" is visible. Shadows cast by the morning sun extend from the peaks towards the northwest. The peaks of all of the Four Islands have snow cover; this is distinct from the clouds due to both higher brightness (white versus gray) and specific location on the landscape.
