Which Alaskan Island Is the Westernmost Point of the United States?

When it comes to determining the westernmost point of the United States, many people might think of the Aleutian Islands in Alaska. However, the actual answer might come as a surprise. The westernmost point of the United States is not located on any of the well-known Aleutian Islands, but rather on a remote and lesser-known island called Amatignak.

Amatignak Island is situated in the Rat Islands group, which is a part of the Aleutian Islands chain. It is approximately 9 miles long and 3 miles wide, making it a relatively small island in comparison to others in the region. The island is uninhabited and is primarily composed of rugged terrain and grassy meadows, surrounded by cliffs and rocky shores.

Geographically, Amatignak Island lies at a longitude of about 179°, 4 minutes west. This location makes it the westernmost point of the United States, even surpassing the more prominent Attu Island, which is often mistakenly believed to hold this title.

Amatignak Island is not only significant for being the westernmost point of the United States but also for its unique ecology. The island is home to a variety of bird species, including puffins, kittiwakes, and cormorants. Additionally, marine mammals such as sea lions, seals, and sea otters can be found in the surrounding waters.


Q: How can I visit Amatignak Island?
A: Due to its remote location and lack of infrastructure, visiting Amatignak Island can be quite challenging. It is not a popular tourist destination, and there are no regular transportation services available. If you are interested in exploring the island, it is advisable to join an organized expedition or charter a private boat. However, keep in mind that access to the island might be restricted to protect its delicate ecosystem.
