Anchorage, Alaska

Anchorage is the most populous city in the U.S. state of Alaska.

It serves as a vital urban center in Southcentral Alaska. The city is located on a peninsula at the terminus of the Cook Inlet. This peninsula is formed by two large waterways. The Knik Arm lies to the north of the city. The Turnagain Arm lies to the south.

The Municipality of Anchorage is the fourth-largest city by land area in the United States. As of the 2020 census, the city had 291,247 residents. This number represents nearly 40 percent of the total population of Alaska. The broader Anchorage metropolitan area includes the Matanuska-Susitna Borough. That larger region held 398,328 people in 2020. This accounts for more than half of the state's population.

Human history in the Cook Inlet area began thousands of years ago. Archaeological evidence found at Beluga Point suggests habitation started 5,000 years ago. A group of Alutiiq people likely arrived by kayak. A second wave of Alutiiq occupation began roughly 4,000 years ago. A third wave arrived about 2,000 years ago. Around 500 AD, the Chugach Alutiiq were displaced by Dena'ina Athabaskans. These people entered the region through mountain passes. The Dena'ina did not have fixed settlements. They migrated according to seasonal changes. In summer, they fished along coastal streams and rivers. In early fall, they hunted moose, mountain goats, and Dall sheep. During late fall, they gathered berries. In winter, they stayed near trading junctions. They traded with other Dena'ina and Ahtna tribes.

European exploration brought new maps to the region. Captain James Cook was among the first to map the Alaskan coastline. He was searching for the Northwest Passage. This was a route to reach the Pacific from Europe more easily. On May 15, 1778, Cook entered an inlet between Cape Douglas and Mount St. Augustine. He anchored his ship, the HMS Resolution, at a place he called "Anchor Point." This was near a creek he named "Ship Creek."

Cook spent ten days exploring the area. He sent William Bligh to scout the north arm. Bligh met Dena'ina Natives who identified the Knik Arm. Cook later sailed south to scout the other arm. He found no passage there. He named the waterway "River Turnagain" because of his frustration. Many geographical names from Cook's era are still used today.

In the 19th century, Russian presence was established in South-Central Alaska. They built trading posts along the Cook Inlet. One post was at Niteh on the Palmer Flats. This presence created small agricultural communities in places like Ninilchik and Eklutna. However, the Russians also introduced diseases like smallpox. This had a devastating effect on the local Native population. In 1867, the United States purchased Alaska from Russia. Secretary of State William H. Seward brokered the $7.2 million deal. Some critics called it "Seward's folly" or "Walwussia." Later, gold was discovered along the Turnagain Arm in 1888. This led to many new towns like Girdwood and Spenard.

Modern Anchorage grew from a railroad construction site. In 1915, a tent city formed near the mouth of Ship Creek.

Workers arrived to build the Alaska Railroad. The waters at Ship Creek were deep enough for ships to dock. Anchorage was officially incorporated in November 1920. The city was designed with order and rigidity. This was partly to enforce Prohibition laws. In 1975, the City of Anchorage merged with the Greater Anchorage Area Borough. This created the current Municipality of Anchorage. The municipal limits include the urban core and Chugach State Park. Because the area is so large, less than 10 percent of it is actually populated. Most people live in the "Anchorage Bowl."

Natural disasters have also shaped the city's development. On March 27, 1964, the Good Friday earthquake struck. It had a magnitude of 9.2. This was the fourth-largest earthquake ever recorded. The shaking lasted nearly five minutes. It caused $116 million in damages.

The ground in Anchorage consists of glacial silt. The shaking caused soil liquefaction. This means the ground acts like a liquid. It caused massive cracks in roads. In the Turnagain neighborhood, some homes sank from 300 feet to sea level. Broadcaster Genie Chance helped during the crisis. She stayed on the air for 24 hours to coordinate relief efforts. Rebuilding and recovery defined the rest of the 1960s.

Today, Anchorage is a global hub for transportation. Its location is nearly equidistant from New York City, Tokyo, and Murmansk.

This makes the Ted Stevens Anchorage International Airport very important. It is within a 10-hour flight of 90 percent of the inhabited global north.

International cargo flights use the airport as a refueling stop. It is also home to a major FedEx hub. The city's economy also relies on the military and the oil industry. The discovery of oil in Prudhoe Bay in 1968 shifted the economy toward oil. Anchorage remains a vital connection point for the world.
