Seek the history of Aleutian Islands.

Arc islands, which extend from the top of alaska peninsula to the southwest and then to Atu, are 65,438+0,800 kilometers (65,438+0,65,438+000 miles) long and separate the Bering Sea (north) from the Pacific Ocean (south).

The archipelago includes 14 large islands, 55 smaller islands and thousands of small islands, with a total area of 17666 square kilometers (682 1 square mile), which is a part of Alaska.

The main island groups from east to west are Fox, Sishan, Ande Lanoff, Lat and nearby.

Comandor Islands near kamchatka peninsula (Russian Federation) are part of Aleutian Islands geographically rather than politically.

Located in the North Pacific Ocean, it is a group of volcanic islands that separate the Bering Sea from the Pacific Ocean.

Nymark Island in the east and attu in the west consist of more than 70 small islands.

It is about 2250 kilometers long and covers an area of1.8000 square kilometers.

Structurally, it is a part of Cordillera Mountains in western North America. Most of the islands are volcanic islands, and some volcanoes still have intermittent activities.

The climate of the islands is influenced by Alaska warm current and polar ocean air mass, with rain, fog and strong wind.

The temperature difference between the four seasons is small, and the winter temperature in Aleutian Islands is higher than that in the eastern part of the continent at the same latitude.

Because of the strong wind, there are no trees on the island, and the vegetation is mainly meadow and moss.

The islands are part of the "ring of fire" around the Pacific Ocean and belong to the semi-submerged part of the Aleutian Mountains in Alaska.

Most of them are volcanic islands, and some volcanoes are still active.

The rocks on the shore are densely covered and worn by the waves, which is extremely dangerous to approach.

The land rises from the coast, forming steep mountains.

The main routes between the islands include Nymark, Umnak, Amukta and Seguam.

The temperature difference between the four seasons is small, windy, rainy and foggy.

There are few trees on the island, covered with weeds and many flowering plants.

Alaska National Marine Wildlife Sanctuary in Aleutian Islands is located between Nymark Island (east) and attu (west), with an area of 1 1 000 square kilometers (4,250 square miles).

By controlling the number of wild animals (mainly sea otters and seals), nature reserves have protected Aleutians who have always relied on hunting and fishing from the threat of hunger.

Raising blue foxes has brought employment opportunities to many people.

There are a large number of residents in Unalaska and adak Island.

Analaska Island is the earliest and largest settlement (1760? 1775), once the headquarters of the large US Coast Guard fleet.

This fleet once patrolled the seal hunting ground in Pribil, Biloff Islands in the northern part of the island.

Adak base, the second largest residential area, was a naval base established in 1942.

174 1 year, Russia sent Danish Vitus Bering and Russian Alexei chirikov to explore.

After the fleet was separated in a storm, chirikov discovered several islands in the east and Bering discovered several islands in the west.

When Siberian hunters learned that fur animals were abundant here, they rushed to the Commander Islands and gradually moved eastward, crossing the Aleutian Islands to the mainland, giving Russia a foothold in North America.

Due to Russian conquest and slaughter, the Aleutians, the indigenous people, were almost extinct.

1867 Russia sold Alaska and the islands to the United States.

During the Second World War, the strategic importance of the small bay on the island of Edak in the Aleutian Islands was seen.

1942, Japanese troops occupied Artu and Kiska Island.

A year later, after 19 days of fierce fighting, the United States recaptured Artu.

During the Cold War, the military base of Aleutian Islands was an important link in the strategic defense of the North American continent.

Population: 1 1, 942( 1990).

The United States has established a national wildlife sanctuary with an area of 1. 1.000 square kilometers between Nymark Island and attu.

Residents mainly live in Unalaska, Edak and Semia, engaged in fishing and domesticating fur animals.

The islands are strategically located and are an important naval and air base of the United States in the Pacific region.

Edak Island and Shemia Island are air relay stations; Port Holland on Unalaska Island is a natural deep-water port and naval base.

When we open the map, we will see that there is a semicircular banded archipelago in the North Pacific Ocean southwest of Alaska, USA, which extends intermittently from east to west, and almost reaches kamchatka peninsula in Asia.

It is more than 2700 kilometers long.

This is a wonderful nature. If a circle is drawn with a compass with Anadel Bay at the northern end of the Bering Sea as the center point and the distance from the center point to the Aleutian Islands as the radius, it can be found that the part of the Aleutian Islands extending from east to west is almost identical with the trajectory of the circle.

If the Bering Sea is compared to a river, then the Aleutian Islands are like a long series of curved stepping stones. Starting from alaska peninsula, you can "walk" to the other side of the river by stepping on these "stones".

The Aleutian Islands are a part of alaska peninsula. Together with alaska peninsula, they belonged to Tsarist Russia. 1867, Americans bought it from Russian czar Alexander II for $7.2 million.

If the Russian czar had known that gold was buried underground in Alaska and the Aleutian Sea was a treasure house with important military value, he would never have sold it to "Uncle Sam" so cheaply.

Soon after Russia sold Alaska to the United States, gold mines were discovered here.

1903 Alaska, as the 49th state in the United States, paid more than $9.5 million in taxes to the United States within one year.

Since then, the output value of fish, fur and gold in Alaska has been around $6543.8+$500 million every year.

Alaska and Aleutian Islands on the map cross the North Pacific Ocean in the form of the first quarter moon, which is the strategic location of the United States in the Pacific Ocean. They are on the shortest road from Japan and the Far East to North America and Northern Europe, and they are also the closest places to the United States and Russia.

The Aleutian Islands consist of five groups of islands: Fox, Andreyanov, Sishang, Rath and Neil. There are 0/59 large and small islands/kloc-with a total area of about 65,438+8,000 square kilometers and a population of about 8,000, of which the garrison is the main one and the rest are aborigines.

Among these islands, there are only three excellent ports, among which the former Dutch port near the east coast of alaska peninsula is of strategic military value and has always been the naval and air base of the United States.

The northwestern tip of the Aleutian Islands is the attu, the last island in the United States and the nearest island adjacent to Russia.

There are many ports on this island, and the situation is very dangerous. This is the natural anchorage for ships.

Aleutian Islands are volcanic islands, and some volcanoes are still active intermittently, so earthquakes, seabed changes and new islands often occur.

The location of the Aleutian Islands has become the natural dividing line between the Pacific Ocean and the Bering Sea.

Because the archipelago is dominated by the maritime climate of the Arctic Ocean, the cold current of the Arctic Ocean always comes too early every September. /kloc-It has snowed heavily since October, and it will be covered with snow until June next year.

In the long winter, there is only a bleak scene filled with heavy snow, storms or dense fog, but the sea near the island is not frozen all year round, and thin ice will form in the coldest time.

The aquatic resources here are extremely rich. The Bering Sea to the north of the archipelago is famous for its rich fish and is the first fishing ground in the world.

The once desolate Aleutian Islands, after the hard construction of Americans, showed a prosperous scene: the newly-built aquatic products processing factory smelled of fish, rows of docks that were about to be completed were under intense construction, and fishing nets and crab cages piled up like mountains.

In the harbor, thousands-ton modern fishing boats shuttle back and forth, and in the anchorage in the distance, thousands-ton cargo ships dock, and the whirring of bulldozers and pile drivers are intertwined. From time to time, the roar of the plane came from the air, which added to the noisy atmosphere.

Because of their important military position and great economic value, these islands are called "western delta" by Americans.

Americans who come here to develop and immigrants from China, Viet Nam and the Philippines are creating a new history of the Aleutian Islands with their hard-working hands.
