Kiska

Kiska is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Kiska rather than just read about it. In short: Kiska (Aleut: Qisxa, Russian: Кыска) is one of the Rat Islands, a group of the Aleutian Islands of Alaska. It is about 22 miles (35 km) long and varies in width from 1.5 to 6 miles (2.4 to 9.7 km).

Key takeaways

  • Kiska belongs to earth science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Kiska to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Kiska from memory before moving on to harder problems.

Reference excerpt

Kiska (Aleut: Qisxa, Russian: Кыска) is one of the Rat Islands, a group of the Aleutian Islands of Alaska. It is about 22 miles (35 km) long and varies in width from 1.5 to 6 miles (2.4 to 9.7 km). It is part of Aleutian Islands Wilderness and as such, special permission is required to visit it. The island has no permanent population.

History

European discovery (1741) In 1741 while returning from his second voyage at sea during the Great Northern Expedition, Danish-born Russian explorer Vitus Bering made the first European discovery of most of the Aleutian Islands, including Kiska. Georg Wilhelm Steller, a naturalist-physician aboard Bering's ship, wrote:

On 25 October 1741 we had very clear weather and sunshine, but even so it hailed at various times in the afternoon. We were surprised in the morning to discover a large tall island at 51° to the north of us. Prior to European contact, Kiska Island had been densely populated by native peoples for thousands of years.

After discovery (1741–1939) Kiska, and the other Rat Islands, were reached by independent Russian traders in the 1750s. After the initial exploitation of the sea otter population, Russians rarely visited the island as interest shifted further east. Years would frequently pass without a single ship landing. Starting in 1775, Kiska, the Aleutian Islands, and mainland Alaska became fur trading outposts for the Russian-American Company managed by Grigory Shelekhov. In 1867, U.S. Secretary of State William H. Seward negotiated the purchase of Alaska with the Russian Empire. Kiska was included in the purchase.

World War II (1939–1945)

The Japanese No. 3 Special Landing Party and 500 marines went ashore at Kiska on June 6, 1942, as a separate campaign concurrent with the Japanese plan for the Battle of Midway. The Japanese captured the sole inhabitants of the island: a small United States Navy Weather Detachment consisting of ten men, including a lieutenant, along with their dog. (One member of the detachment escaped for 50 days. Starving, thin, and extremely cold, he eventually surrendered to the Japanese.) The next day the Japanese captured Attu Island. The military importance of this frozen, difficult-to-supply island was questionable, but the psychological impact upon the Americans of losing U.S. soil to a foreign enemy for the first time since the War of 1812 was tangible. During the winter of 1942–43, the Japanese reinforced and fortified the islands—not necessarily to prepare for an island-hopping operation across the Aleutians, but to prevent a U.S. operation across the Kuril Islands. The U.S. Navy began operations to deny Kiska supply which would lead to the Battle of the Komandorski Islands. During October 1942, American forces undertook seven bombing missions over Kiska, though two were aborted due to weather. Following the winter, Attu was recaptured, and bombing of Kiska resumed until a larger American force was allocated to defeat the expected Japanese garrison of 5,200 men. The Japanese, aware of the loss of Attu and the impending arrival of the larger Allied force, withdrew their troops on July 28 under the cover of fog, without being detected by the Allies. On August 15, 1943, an invasion force consisting of 34,426 Allied troops, including elements of the US 7th Infantry Division, 4th Infantry Regiment, 87th Mountain Infantry Regiment, 5,300 Canadians (mainly the 13th Infantry Brigade from the 6th Canadian Infantry Division), with supporting units including two artillery units from the US 7th Infantry Division, 95 ships including three battleships and a heavy cruiser and 168 aircraft landed on Kiska in Operation Cottage, only to find the island abandoned. Despite the lack of Japanese presence, Allied casualties during this invasion nevertheless numbered close to 200, either from bad weather, Japanese booby traps or friendly fire. As a result of the brief "friendly fire" engagement between U.S. and Canadian forces, 28 Americans and four Canadians were killed. There were an additional 130 casualties from trench foot. The destroyer USS Abner Read hit a mine, resulting in 87 casualties. That night the Imperial Japanese Navy warships, thinking they were engaged by Americans, shelled and attempted to torpedo the island of Little Kiska where the Japanese soldiers were waiting to embark. Admiral Ernest King reported to the secretary of the Navy, Frank Knox, that the only things that remained on the island were dogs and freshly brewed coffee. Knox asked for an explanation and King responded, "The Japanese are very clever. Their dogs can brew coffee".

Since World War II In 1985 the Japanese occupation site on the island was designated a National Historic Landmark and part of Aleutian Islands World War II National Monument. The island is also a part of the Alaska Maritime National Wildlife Refuge (AMNWR) and contains the largest colony of least auklets (over 1,160,000 birds) and crested auklets. Research biologists from Memorial University of Newfoundland have been studying the impact of introduced Norway rats on the seabirds of Kiska since 2001. Much of the aftermath of World War II is still evident in Kiska. The slow erosion processes on the tundra have had little effect on the bomb craters still visible both from the ground and in satellite images on the hills surrounding the harbor. Numerous equipment dumps, tunnels (some concrete-lined), Japanese gun emplacements, shipwrecks, and other war relics can be found, all untouched since 1943. In 1983, a memorial plaque was placed on Kiska by the 87th Mountain Infantry Regiment, inscribed:

To the men of Amphibious Task Force 9 who fell here August 1943 placed here August 1983 by 87th Mountain Infantry Regiment. In September 1989, divers from the United States Navy rescue and salvage ship USS Safeguard (ARS-50) surveyed the wreck of the Imperial Japanese Navy submarine Ro-65, which sank in the harbor at Kiska with the loss of 19 lives on November 3, 1942. On August 22, 2007, the submarine USS Grunion, which disappeared with a crew of 70 during World War II, was found in 1,000 metres (3,281 ft) of water off Kiska. There were no alterations to the landscape since World War II including the traces of the war. Unexploded ammunition is scattered throughout the landscape.

Worked examples

Example 1 — a first encounter with Kiska

Start with the simplest possible case. Write down what Kiska claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Kiska before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Kiska ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Kiska

In research
Kiska appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Kiska in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Kiska is common in secondary-school and first-year university syllabi. It links to neighbouring topics Alaska Maritime National Wildlife Refuge, Aleutian Islands campaign, Cinder cones of the United States, so understanding it makes those chapters shorter.
In everyday life
Look for Kiska outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
