Of course the site is conveniently located on the China Lake naval gunnery range, or some such installation in Death Valley. (I know this because this was in a book called Mysterious California).
You'd have to be nuts to accept this tale at face value, since the enterance has mysteriously disappeared. Speaking of nuts, it is alleged that Charles Manson intended to lead his followers into such an underground world after starting a cataclysmic race war (can't back that up, neither could the book where i read it).

The most likely explanation is that these are the burrows of a race of highly evolved nuclear red ants which I flushed down the toilet 10 years ago after finishing my 6th grade science project.

Aw man who would follow some tunnel TWENTY miles?! I would stop after 20 feet. And if I was that guy there would be no way i was going in there even if he told me it was ok.

A very cute and amusing old tale that relies on the reader having never been to Death Valley and having not done much research on it.

The place does get rain, and any good rain would cause the tunnels to collapse.
