We just learned about the Carlini Base.
Another research base in Antarctica is the Pole of Inaccessibility Research Station.
This is in the place on Antarctica that is the farthest from any point of water where a boat could land with explorers.
Since it's so hard to get to it's called the most inaccessible.
The Russians built a small base for 4 people there in 1958, and they stayed for 8 days and then left.
Since then the base has been covered by snow, and the only part showing is the statue of the old Russian leader Lenin that was on the top of the base.
Some people still visit the spot to do some research, but the base is buried so no one stays there anymore.
