Walking from the US to Russia: A Frozen Shortcut Through Time

Imagine this: You wake up in the U.S., take a short walk across some frozen ice, and suddenly… it’s tomorrow, and you’re in Russia! Sounds like a sci-fi movie, right?

Between Alaska and Russia sit the Diomede Islands: Little Diomede (U.S.) and Big Diomede (Russia).

In winter, when the Bering Strait freezes over, a natural ice bridge forms between them.

The islands are just 2.4 miles (3.8 km) apart but are separated by the International Date Line—meaning they’re also 21 hours apart in time!

That’s why Big Diomede is sometimes called "Tomorrow Island," while Little Diomede is "Yesterday Island."

Technically, you could walk between the two—if you don’t mind braving Arctic conditions and, oh yeah, breaking international border laws!
