Aleutian Islands

The Aleutian Islands —also called the Aleut Islands, Aleutic Islands, or, before the Alaska Purchase in 1867, the Catherine Archipelago—are a chain of 14 main, larger volcanic islands and 55 smaller ones.

Geology
Motion between the Kula Plate and the North American Plate along the margin of the Bering Shelf (in the Bering Sea north of the Aleutian arc) ended in the early Eocene. The Aleutian Basin, the ocean floor north of the Aleutian arc, is the remainder of the Kula Plate that was trapped when volcanism and subduction jumped south to its current location at 56 Ma. The Aleutian island arc formed in the Early Eocene (55–50 ) when the subduction of the Pacific Plate under the North American Plate began. The arc is made of separate blocks that have been rotated clockwise. The basement underlying the islands is made of three stratigraphic units: an Eocene layer of volcanic rock, an OligoceneMiocene layer of marine sedimentary rock, and a PlioceneQuaternary layer of sedimentary and igneous rock. ==Geography==
Geography
in the Aleutian Islands The islands, known before 1867 as the Catherine Archipelago, include six groups (east to west) • Fox Islands (the main islands are Unimak, Akutan, Unalaska and Umnak) • Islands of Four Mountains (the main islands are Yunaska and Chuginadak) • Andreanof Islands (the main islands are Adak, Atka, Amlia, Seguam, Kanaga and Tanaga) • Rat Islands (the main islands are Kiska and Amchitka) • Near Islands (the main islands are Attu Island, Agattu Island and the Semichi Islands - Alaid, Nizki and Shemya) • Commander Islands (the main islands are Bering and Medny) All six are located between 51° and 55° N latitude and 172° E and 163° W longitude. The largest islands in the Aleutians are Attu, and Unalaska, Umnak, and Unimak in the Fox Islands. The largest of those is Unimak Island, with an area of 1,571.41 mi2 (4,069.9 km2), followed by Unalaska Island, the only other Aleutian Island with an area over 1,000 square miles (2,600 km2). The axis of the archipelago near the mainland of Alaska has a southwest trend, but at Tanaga Island (about 178° W) its direction changes to the northwest. This change of direction corresponds to a curve in the line of volcanic fissures that have contributed their products to the building of the islands. Such curved chains are repeated about the Pacific Ocean in the Kuril Islands, the Japanese chain, and in the Philippines. All these island arcs are at the edge of the Pacific Plate and experience much seismic activity, but are still habitable; the Aleutians lie between the Pacific and North American tectonic plates. The general elevation is greatest in the eastern islands and least in the western. The island chain is a western continuation of the Aleutian Range on the mainland. The great majority of the islands bear evident marks of volcanic origin, and there are numerous volcanic cones on the north side of the chain, some of them active; many of the islands, however, are not wholly volcanic, but contain crystalline or sedimentary rocks, and also amber and beds of lignite. The coasts are rocky and surf-worn, and the approaches are exceedingly dangerous, the land rising immediately from the coasts to steep, bold mountains. Alfred Russel Wallace's 1879 book Australasia, Ian Todd's 1974 book Island Realm: A Pacific Panorama and Dean Kohlhoff's 2002 book Amchitka and the Bomb: Nuclear Testing in Alaska all associate the Aleutian Islands with the Oceania region due to their status as remote islands in the Pacific. The islands, having biogeographical and ethnocultural affinities to North America, are not ordinarily considered a part of the region.

Climate
's climate creates a tundra. The climate of the islands is oceanic, with moderate and fairly uniform temperatures and heavy rainfall. Fogs are almost constant. Summer weather is much cooler than Southeast Alaska (around Sitka), but the winter temperature of the islands and of the Alaska Panhandle is nearly the same. During the winter, the islands become the center of a semi-permanent low-pressure area called the Aleutian Low. The mean annual temperature for Unalaska, the most populated island of the group, is about 38 °F (3 °C), being about 30 °F (−1 °C) in January and about 52 °F (11 °C) in August. The highest and lowest temperatures recorded on the islands were 78 °F (26 °C) and 5 °F (−15 °C), respectively. The average amount of annual rainfall is about ; Unalaska, with about 250 rainy days per year, is said to be one of the rainiest places within the U.S. ==Flora==
Flora
in the Aleutian Islands, Alaska The growing season lasts approximately 135 days, from early in May until late in September, but agriculture is limited to the raising of few vegetables. With the exception of some stunted willows, the vast majority of the chain is devoid of native trees. ==Fauna==
Fauna
s near Unimak Island, eastern Aleutian Islands s haul out on Amak Island. The Aleutians are home to many large colonies of seabirds. Buldir Island has 21 breeding seabird species, including the Bering Sea-endemic red-legged kittiwake. Large seabird colonies are also present at Kiska, Gareloi, Semisopochnoi, Bogoslof, and others. The islands are also frequented by vagrant Asiatic birds, including the common rosefinch, Siberian rubythroat, bluethroat, lanceolated warbler, and the first North American record of the intermediate egret. The habitats of the Aleutians are largely unspoiled, but wildlife is affected by competition from introduced species such as cattle, caribou, and foxes. Nearly all of the Aleutians are protected as part of the Alaska Maritime National Wildlife Refuge and the Aleutian Islands Wilderness. Observations have identified sea otters as a keystone species along the coasts of many of the Aleutian Islands. Their presence encourages the growth of kelp forests, as the otters control sea urchin populations (as large populations of sea urchins can create urchin barrens by clearing away kelp stands). == Demographics ==
Demographics
, Adak Island The native people refer to themselves as Unangan, and are now generally known by most non-natives as the Aleut. The Aleut language is one of the two main branches of the Eskimo–Aleut language family. This family is not known to be related to any others. The 2020 U.S. census recorded a population of 7,152 on the islands, of whom 4,254 were living in the main settlement of Unalaska. == Economy ==
Economy
On the less mountainous islands, the raising of sheep and reindeer was once believed to be practicable. There are bison on islands near Sand Point. Sheep raising seems to have died off with the advent of synthetic fibers, which lowered the value of wool. During the 1980s, there were some llama being raised on Unalaska. The current economy is primarily based on fishing, and the presence of U.S. military. The only crop is potato. Chickens are raised in barns under protection from the cold. ==Transportation==
Transportation
In addition to a partial air service and a ferry service, the Alaska Marine Highway passes through many of the U.S. islands. ==History==
History
Prehistory Because the islands stretch like a broken bridge from the continent Asia to the continent North America, many anthropologists hypothesize they were a route of the first human occupants of the Americas. However, the earliest known evidence in public recorded history of human occupation in the Americas is found much farther south. The early human sites in the Bering Sea were probably submerged by rising waters and sand during the current interglacial period. People living in or on the Aleutian Islands developed skills in hunting, fishing, and basketry. The baskets were woven with shredded stalks of beach rye. Russian period ian man with a Creole woman in the Aleutian Islands , Aleutian Islands Explorers, traders and missionaries arrived from Russia beginning in 1741. In 1741 the Russian government sent Vitus Bering, a Danish-born Russian, and Aleksei Chirikov, a Russian, in the ships Saint Peter and Saint Paul on a voyage of discovery in the Northern Pacific. After the ships were separated by a storm; Chirikov discovered several eastern islands of the Aleutian group, and Bering discovered several of the western islands. Bering was shipwrecked and died in the Komandorski Islands (Commander Islands); one of which now bears his name (Bering Island), along with the surrounding Bering Sea. The survivors of Bering's party reached the Kamchatka Peninsula in a boat constructed from the wreckage of their ship, and reported the islands were rich in fur-bearing animals. Within a generation, the day-to-day administration of the Russian-American colonies was largely in the hands of native-born Alaskans. Reversing the usual trend in colonization where indigenous technologies are replaced, the Russians adopted the Aleut kayak, or baidarka, sea otter hunting techniques, and the working of native copper deposits. The Russians instituted public education, preservation of the Aleut language through transliteration of religious and other texts into Aleut via an adaptation of the Cyrillic alphabet, vaccination of the native population against smallpox, and science-based sea mammal conservation policies that were ahead of their time. By 1760 the Russian merchant Andrian Tolstykh had made a detailed census in the vicinity of Adak and extended Russian citizenship to the Aleuts. During his third and last voyage in 1778, Captain James Cook surveyed the eastern portion of the Aleutian archipelago, accurately determined the position of some of the more important islands, and corrected many errors of former navigators. The U.S. Navy, having broken the Japanese naval codes, proceeded as if this was just a diversion, and it did not expend large amounts of effort in defending the islands. More than 90 Americans were taken to Japan as prisoners of war. The United States moved most of the remaining civilian population (over 800) of the Aleutians and Pribilovians to camps in the Alaska Panhandle. In May 1943, American forces invaded Japanese-held Attu and defeated the Japanese. In August 1943, American and Canadian troops launched an invasion of Kiska, in which 34,426 men composed of both Americans and Canadian participated; however, Japanese forces had already evacuated the island, ending the campaign in the islands. The invasion was an embarrassment for the Allied forces as the entire Japanese force of 5,183 men had left the island on July 28 without the Americans noticing; however, the Americans suffered significant casualties during their "invasion"—313 men died as a result of accidents, with many dying due to accidental fire. President Roosevelt visited Adak in 1944, meeting with commanders and eating with soldiers of the garrison. This was his first and only trip to the Aleutian Islands and Alaska as a whole. A rumor spread that FDR had accidentally left his Scottish Terrier "Fala" on one of the Islands and had to send a destroyer to retrieve the dog, costing taxpayers several million dollars. The President made fun of these rumors during a talk with the Teamsters Union in Washington DC, now known as the "Fala Speech". At this speech the President joked with the crowd saying, "Well, of course, I don't resent attacks, and my family doesn't resent attacks, but Fala does resent them!" June 3, 2002, was celebrated as Dutch Harbor Remembrance Day. The governor of Alaska ordered state flags lowered to half-staff to honor the 43 Americans who died during the two-day Japanese air attack in 1942. The Aleutian World War II National Historic Area Visitors Center opened that month. Statehood era The U.S. conducted underground tests of nuclear weapons on Amchitka Island from 1965 to 1971 as part of the Vela Uniform program. The final detonation, the Cannikin, was the largest underground nuclear explosion by the U.S. The Alaska Native Claims Settlement Act became law in 1971. In 1977, the Ounalashka Corporation (from Unalaska) declared a dividend. This was the first village corporation to declare and pay a dividend to its shareholders. The Aleutian Islands were designated a UNESCO biosphere reserve in 1976. The Aleutians were one of 17 biosphere reserves in the United States withdrawn by request of the U.S. government from the programme in June 2017. ==Russian Aleutians==
