During the Wild West, many towns popped up along the trail and eventually went on to become ghost towns. Military bases, though, have sometimes become "ghost bases" – abandoned and left to rot.
Some of these ghost bases are near cities like the Big Apple. Others, like Johnston Atoll, are pretty far off – a nice getaway spot, if not for the history of being used as a storage center for Agent Orange and other interesting stuff.

The climates can be very different – from the burning sands of Johnston Atoll to the frozen flatlands of North Dakota, where America briefly operated a ballistic-missile defense system known as SAFEGUARD.
One base in Croatia that once was home for almost 50 fighter jets was abandoned during the Yugoslav civil war of 1991 – and the wrecks are mostly used by folks seeking some adventure. That base still gets "official" use for law enforcement training.

You can even check out one abandoned facility that will soon fall into the Pacific. No, not Johnston Atoll (it was a re-claimed coral atoll built over the years long before China did the same thing in the South China Sea), but instead the Devil's Slide bunker on the California coast. A lack of maintenance and the natural process of erosion will eventually send this coastal-defense bunker tumbling from commanding heights and into the Pacific.
But if you want one "ghost base" that has captured imaginations worldwide, you can go to either the Ukraine or Siberia to see the Duga Radar Array – an early-warning system meant to detect American missiles. Or just pick up the video games "Call of Duty: Black Ops" and "Stalker" to see representations of the array used.

So, take a peek at this video that tells more about these and some other "ghost bases" – and tell us which "ghost base" you would like to know more about.
