Alaska Island Superlatives Alaska has thousands of
islands. It has more large islands
than any other state, and it has the largest total island area of any state. SIZE Largest
island The
largest island in Alaska is Kodiak Island, with an area of 3,588 sq mi /
9,293 sq km. It is the 2nd largest island
of the United States. Alaska’s largest lake island is Porcupine
Island, at the east end of Iliamna Lake, at 5 sq mi / 13 sq km. Alaska
has many large river islands, some of more than 20 square miles, especially
in the Yukon River. However, their shifting
nature makes their areas difficult to measure precisely With
tens of thousands of islanders, Alaska has an unusually high percentage of
its population living on islands.
Alaska is also unusual in that its most populous island is unbridged. The
most populous island in Alaska is Revillagigedo Island, site of the town of
Ketchikan, with about 13,000 people. Kodiak
Island is a close second, with slightly fewer than 13,000 inhabitants as of
2008. Most
populous unbridged island Alaska
has more inhabited, unbridged islands than most
other states. The most populous of these
is Kodiak. Most populous freshwater island / river island Garden
Island in Fairbanks is the most populous river island in the state. Formed by the Chena River and its offshoot
Noyes Slough, it hosts several residential areas. MISCELLANEOUS Alaska’s
tallest island is Unimak Island, which rises 9,414 feet / 2,869 meters from
sea level to the top of Shishaldin Volcano. Porcupine
Island in Iliamna Lake is Washington’s tallest lake island: it rises 508 feet
/ 113 meters above lake level. Tallest
river island Farm
Island, in the Stikine River delta near Mitkof,
rises 2,492 feet / 760 meters, but it is partly surrounded by sea. The
most common name for islands in Alaska is "Long Island," with 11 examples. Largest island on
an island Alaska
has several of the largest islands on another island in the United
States. The largest is in Hasselborg Lake, on Admiralty Island, with an area of
about 56 acres / 23 hectares. Alaska
has no islands below sea level. |
