A Book Called "Entrances To Subterranean Tunnels"

I was doing a search on secret bases on the internet and found this web site:
www.ufos-aliens.co.uk...
which says there is a book called "Entrances To Subterranean Tunnels" and that it list all known entrances to underground bases. Has anyone else heard of this book before. The site also has a list of underground bases and some info on them. So does this book exist?

This is a website wich has a list of a lot of bases located in the different states of the US:

There is another book called:

Underground Bases and Tunnels: What is the Government Trying to Hide?
by Richard Sauder, Ph.D.
Dracon Press, 1995
ISBN 0-9644979-0-5

softcover, 142 pages, 50 photos & illustrations

I would recommend reading the book Shadowhawk mentioned by Richard Sauder. Anyone interested in underground bases and their construction would definitely enjoy it.

If you are unable to obtain a copy (it may be out-of-print), I have seen a PDF version available on the web in the past.

I love these 'lists of secret bases' that purport Mt. Shasta and Lassen Peak as secret bases.

They are active volcanoes and anyone who would build a base inside such geologically unstable mountains is pretty stupid. Especially mountains visited by thousands of tourists every year hiking and camping all over them.

I live near there and I can show you many lava tubes and natural caves, but no UFO bases.

This one doesn't even pass the giggle test.
