Alaska is the easternmost state in the United States. Alaska is also the westernmost state in the United States. Both statements are true, and yes, this is as weird as it sounds.
Most people assume the answer is obvious: Hawaii is the westernmost because it's isolated in the Pacific, and Maine is the easternmost because it juts into the Atlantic. We've seen the maps. We know which way is which. But the maps, it turns out, are lying to you by necessity. The moment you acknowledge that Earth is a sphere and longitude lines converge at the poles, the entire concept of "easternmost" and "westernmost" becomes philosophically unstable. Alaska, thanks to its Aleutian Islands, exploits this instability perfectly.
Here's what's actually happening: The Aleutian Islands stretch west from mainland Alaska toward Russia, and crucially, they cross the 180th meridian—the line that separates the Eastern and Western hemispheres. According to geographic research compiled by Mental Floss, this makes Alaska the only U.S. state that occupies both hemispheres simultaneously. The westernmost islands of Alaska (the Near Islands, which include places like Attu Island) lie east of the 180th meridian when measured the "short way" around the globe, but west of it when measured the "long way." This means Attu Island, part of Alaska, is technically further east than Key West, Florida, depending on which direction you're measuring. At the same time, those same islands are further west than any other U.S. territory because they're on the western side of the date line.
The reason this breaks our intuition is that we're trained to think of Earth in two dimensions. On a flat map, directions make sense: north is up, west is left, east is right. But longitude doesn't actually work that way. Lines of longitude are not separate paths running parallel to each other—they're all great circles passing through both poles. At the equator, moving east and west feels real and directional. But at the poles, the concept becomes nonsensical. You can't go further east or west at the North Pole; you're already at the intersection of all meridians. The Aleutian Islands, while not at the pole itself, are far enough north and stretched far enough west that they create this cartographic Gordian knot.
Why does this happen? Geography doesn't care about human convenience. The Aleutian Islands are the result of tectonic activity along the Pacific Ring of Fire, and their position 51 degrees north latitude is simply where the geology happened to put them. The 180th meridian, meanwhile, was established by international convention in 1884 as a practical way to standardize time zones and date changes. When you draw a line from pole to pole through the middle of the Pacific Ocean, it's bound to slice through whatever archipelago happens to be in the way. Alaska just had the misfortune—or fortune—of being positioned such that its western reach crosses this arbitrary but essential boundary.
The takeaway here isn't just that maps lie, though they do. It's that our everyday language for describing geography assumes a flat world. We use words like "easternmost" as though they have objective meanings, but they're only meaningful within a two-dimensional framework. Once you acknowledge that Earth is a sphere, you realize these terms are context-dependent, perspective-dependent, and often meaningless. Alaska simply makes this philosophical confusion unavoidable, forcing us to confront the gap between how we talk about geography and how geography actually works.
