About Alaska

Where in the United States is Alaska? Location map of the State of Alaska in the US.

The largest US state occupies a huge peninsula in the extreme northwest of North America. Its 10,690 km (6,640 mi) coastline stretches along the Beaufort and Chukchi Seas (both marginal seas of the Arctic Ocean), the Bering Strait and the Bering Sea, and the Gulf of Alaska, an arm of the Pacific Ocean.

Alaska is separated from the 48 contiguous U.S. states by Canada. The Bering Strait, a strait between the Pacific and Arctic Oceans, separates Asia (the Chukchi Peninsula of Russia) from North America (the Seward Peninsula of Alaska).
Alaska is one of two US states not bordered by another state; Hawaii is the other.

Alaska borders Canada to the east (the Canadian provinces of Yukon Territory and British Columbia), and it shares a maritime border with Russia to the west. The state's nickname is "The Last Frontier."

Some History
The history of Alaska dates back to the Upper Paleolithic period. Genetic findings suggest that a single population of modern humans migrated from southern Siberia toward the landmass known as the Bering Land Bridge as early as 30,000 years ago. 16,500 years ago, people moved further into the Americas. ^[1]
Because the Bering Land Bridge is now submerged, archeological artifacts are practically nonexistent. However, archeologists have discovered artifacts on land that provide evidence of human activity in North and South America dating roughly 12,000 years ago.

At the time of European contact by Russian explorers in the mid-18th century, the area was populated by tribes of Alaskan Native people. Alaska was a Russian colony from the 1740s until 1867, when the territory was purchased by the United States from the Russians for $7.2 million. Admission to the Union was on the 3rd January 1959; Alaska was admitted as the 49th state.

After oil was discovered in 1968, a pipeline was completed in 1977 to transport that oil from the North Slope to Valdez, a former gold rush town that became an important port city in Alaska.

Geography of Alaska

Topographic Map of Alaska. (Click map to enlarge)

Area
The state covers an area of 1,723,337 km² (665,384 sq mi) ^[2] ^[3] and is the largest of all US states. By comparison, Alaska is three times the size of the Iberian Peninsula, compared to other US states, Alaska is 2.5 times the size of Texas, and New Jersey would fit in 76 times.
The U.S. federal government owns and manages approximately 65% of the state as public lands, including 24 national parks, 16 wildlife refuges, and two national forests.

Population
Alaska is among the least populated states in the US. In mid-2021, 732,673 people were residents of Alaska. The capital city is Juneau. Spoken languages are English and 20 indigenous American languages.

Largest cities in Alaska are Anchorage (pop.: 291,538), Juneau (pop.: 32,113), Fairbanks (pop.: 31,516), Wasilla (pop.: 10,529), Sitka (pop.: 8,647), Ketchikan (pop.: 8,289), Kenai (pop.: 7,778), and Kodiak (pop.: 5,968).

Climate
A tundra climate dominates the northern third with temperatures around the freezing point, causing permafrost to prevail (the ground stays frozen all year long.) The southern parts of Alaska are mainly characterized by a subarctic climate with very cold winters and short, cool to mild summers. In December 2021, the coldest US state has recorded its hottest-ever December day, amid an unusual winter warm spell. Temperatures soared to a record 19.4C (67F) on the island of Kodiak. ^[BBC] At the same time, temperatures in Nuiqsut (North Slope) were around -40F/C.

Alaska's Regions
Alaska is divided into five major regions (from north to south):

1. The Far North or Arctic Alaska is a vast area roughly between the Yukon River and the Arctic Ocean. Various Alaskan Natives originally inhabited the region; they lived from hunting and fishing.

Along the coast of the Arctic Ocean stretches the flat, boggy coastal plains, known as the Arctic coastal tundra, an ecoregion of solid permafrost characterized by poor drainage with many thaw lakes and ponds which cover up to 50 percent of the surface.

The Brooks Mountain Range (Athabaskan Gwazhał) dominates the landscape south of the gradually rising plains of the North Slope. The mountains extend over 1,100 km (700 miles) in a slight arc from west to east. The Brooks Mountains reach altitudes of between 1,500 and 2,700 m. Mount Isto, with 2.735 m, is the highest peak in the Brooks Range.

Most of Arctic Alaska lies within the Arctic Circle. The area offers midnight sun in the summer and polar nights in winter; the aurora borealis or "northern lights" may be seen between late August and April.

2. South of the Brook Range is the wilderness area of the Interior in central Alaska; it is centered around Fairbanks, the largest city in the Interior and bounded by the Alaska Range in the south. Native Athabaskan people, a hunter-gatherer society, originally inhabited the region.

3. Alaska's Southwest region along Kuskokwim Bay and Bristol Bay includes the Nunivak Island, the Yukon Delta area, Alaska Peninsula and the Aleutian Islands chain, and the Kodiak Archipelago.

4. Southcentral Alaska is situated roughly between the Alaska Range and the south coast at the Gulf of Alaska. Centered around Prince William Sound. The terrain is subdivided into the Mat-Su Valley (Matanuska-Susitna), the Copper River Valley, the Anchorage Area, and the Kenai Peninsula.

5. The Alaskan portion of the Inside Passage (aka the Alaska Panhandle, aka Southeast Alaska) is situated to the southeast of mainland Alaska. The panhandle extends 840 km (520 mi) from northwest to southeast, south of Canada's Yukon Territory and British Columbia along the Gulf of Alaska. Its rugged landscape offers intricate fjords, glacier-shaped mountains and valleys with temperate rainforests, and sparkling blue and white icefields which generate glaciers.

Mountains

When the United States bought Alaska from the Russians for $7.2 million, the package included all ten of the USA's highest mountains.

Number one in altitude is Denali (also known as Mount McKinley and Bolshaya Gora), the highest mountain in the United States and North America with a summit elevation of 6190 m (20,310 ft). The mountain is located in the Alaska Range in the southern part of the peninsula; it is the highest mountain range in the world outside Asia and the Andes.
Denali is considered the world's coldest mountain because it combines a high elevation and a location near the Arctic Circle. Permanent snow and ice cover over 75 percent of the mountain, and enormous glaciers, up to 70 km (45 mi) long and 1 km (3,700 ft) thick, spider out from its base in every direction. ^[WFB]

There are more than 3,000 rivers in the state.

Alaska's chief river is the Yukon; its source is in British Columbia, Canada, and it empties into the Bering Sea. The river is 3,698 km (2,298 mi) long and flows for 3,017 km (1,875 mi) within Alaska. The Yukon ranks third in length of all US rivers, behind the Mississippi and Missouri.
Major tributaries of the Yukon in Alaska are the Porcupine, the Tanana, and the Koyukuk rivers.

Alaska's other big river is the Colville River, one of the northernmost major rivers in North America, rises in the DeLong Mountains and empties into the Beaufort Sea (Arctic Ocean).

The Noatak is a river north of the Arctic Circle. A long section of the Noatak is part of the National Wild and Scenic Rivers System.

The 450 km (280 mi) long Kobuk River in the Arctic region in northwestern Alaska empties into the Kotzebue Sound.

The Kuskokwim in the southwest of the state provides major drainage for a large area of the Alaska Interior and empties into the Kuskokwim Bay on the Bering Sea.

The Susitna River, the "sandy river," empties into the Cook Inlet of the Pacific Ocean.

The Copper River drains a large region of the Wrangell and the Chugach Mountains; it flows into the Gulf of Alaska.

Islands

There are 1,800 named islands in the state, 1,000 of which are located in Southeast Alaska.

The largest island is Kodiak Island in the Gulf of Alaska; it is separated from Alaska's mainland by the Shelikof Strait. The island has an area of 9,293 km² (3,588 sq mi), making it slightly larger than Cyprus.

Glaciers
Alaska has around 100,000 glaciers. About three-fourths of all freshwater in the state is stored as glacial ice.

Situated southeast of Mount Saint Elias is the largest piedmont glacier in the world, the Malaspina Glacier; it is part of the St. Elias Mountains glacier system. The glacier covers an area of 2,200 km² (850 sq mi); this is about half the size of Rhode Island. ^[4]

The Bering Glacier complex is the largest glacier in Alaska with 5,827 km² (2,250 sq mi); the complex includes the Bagley Icefield. Ice fields cover approximately 5% of the state, about 75,110 km² (29,000 sq mi). ^[5]
