I've been told one state in the US is the easternmost, westernmost and northernmost state. How to visit the points?

Question

According to what I've been told, one state (Alaska) has land which is considered the easternmost, northernmost, and westernnmost in all of the USA. What are the three points that allows it to claim this, if it is indeed true, and how to get there?

Answer 1

Alaska is indeed the easternmost, northernmost, and westernmost in all of the USA. General assumption of one state being both easternmost & westernmost in a country is that the state being spanning across the country. But it's not the case with Alaska, below is the explanation from the website World Atlas

As far as the most western state, note how Alaska's Aleutian Islands stretch right up to the edge of the Western Hemisphere at the 180º line of Longitude, thus the most western state in the country.

Alaska is also the answer for eastern, as the Aleutian Islands stretch across the 180º line of Longitude, into the Eastern Hemisphere, and up the edge of the Russian Federation.

I'm searching to get these three points & their co-ordinates. I'll update once I get them.

Update: Co-ordinates of three extreme points as per Wiki -

• Northernmost: Point Barrow, Alaska 71°23'20"N 156°28'45"W
• Easternmost: Pochnoi Point, Semisopochnoi Island, Alaska 51°57'42"N 179°46'23"E
• Westernmost: Amatignak Island, Alaska 51°16'7"N 179°8'55"W

Answer 2

Depends of course on your definition.

If you look at the Aleutian Islands parts of the chain is located in Eastern Hemisphere so technically if you can consider them the eastern most part of the United States, but since you normally go west to get there and considering their proximity to the antimeridian it crosses Amchitka pass they could be considered the westernmost part of the US as well.

Found an interesting article about Extreme Points of the US

When people say that "Everything new is just well forgotten old" I can easily believe it. From travel.SE archives. The last airline that had scheduled service to Attu was Reeve Aleutian Airlines, which ceased operations in 2000.

Found that you can actually fly close to the Point Barrow to Barrow Airport. As far as I can tell only Alaskan Airlines fly there but I could be wrong.
