Somewhere in Siberia, there’s a lake quietly holding 20% of the world’s unfrozen surface freshwater. Just sitting there. Being smug about it.
Lake Baikal is 25 million years old — making it the oldest lake on Earth. It’s also the deepest, plunging to 1,642 meters (5,387 feet). For context, you could stack four Empire State Buildings down there and still have room for a submarine.
It contains more freshwater than all five Great Lakes combined. Together. North America’s whole show, and Baikal just waves.
The water is so clear you can see 40 meters down on a good day. Visibility that would embarrass most swimming pools.
Now add wildlife. Baikal has roughly 3,700 endemic species — creatures found nowhere else on Earth. The star? The nerpa, the world’s only freshwater seal. Nobody’s quite sure how seals ended up landlocked in Siberia, but here we are. There are also endemic fish like the golomyanka — a translucent, oil-rich species that gives birth to live young and dissolves in sunlight if you leave it on the shore.
Russia has a whole ocean’s worth of weird, and it’s 395 miles long.
