The idea that there could be a secret 5,000-years-old underground city hidden somewhere beneath Death Valley, California is fascinating.
Those who entered the subterranean tunnels and visited this marvelous place say the city was once inhabited by an unknown race.
Now, thousands of years later the place had been abandoned, but the visitors saw strange mummies and curious old artifacts.
Is it possible that such a mysterious underground world exist beneath the Death Valley? Where is it located? Who was this strange and unknown race that once dwelled underground?
