About the Insider

Hello.  My name is Dennis Crenshaw, as editor of THE HOLLOW EARTH INSIDER Research Report I want to welcome you to our Media Outlet, Research Depository and bookstore. Someone once said that most scientists think that the only “hollow” in the belief of a Hollow Earth was in the head of the believer. Others call it “a believe of the lunatic fringe.”   Obviously these knuckleheads hadn’t taken the time to look at all of the evidence before their per-determined assessment. This is where THEI comes in. Since 1992 we here at THEI have been committed to providing those interested the most reliable source of Hollow Earth & “underground” information in the world with no spin. (Although I LOVE playing devils advocate once in a while, which I guess technically … is a spin). Oh well. It is what it is . . . Read Complete Report

      Hi Josiah,
      Sorry I didn’t reply earlier. I just had a senior moment and passed you by.
      In answer to your question. Have him go to our DEEPER section of THEI and he will find lots of my personal research into the Hollow Earth and links to the research book.

  2. You’re so cool! I don’t suppose I have read through a single thing like that before.
    So wonderful to discover another person with genuine
    thoughts on this topic. Seriously.. thank you for starting this up.
    This site is one thing that is required on the web, someone with a
    bit of originality!

    Can I simply say what a relief to find somebody that genuinely understands what they are
    discussing on the net. You actually understand how to bring a problem to light
    and make it important. More and more people really
    need to check this out and understand this side
    of your story. I can’t believe you are not more popular given that you certainly possess the gift.

    Hey! I just wanted to ask if you ever have any issues with hackers?
    My last blog (wordpress) was hacked and I ended up losing several weeks of hard
    work due to no data backup. Do you have any solutions to protect against hackers?

  6. Shari says:

    This blog was… how do I say it? Relevant!! Finally I have found something which helped me.
    Thank you!

    I am very intrigued by the Hollow Earth Theory and reading about Admiral Byrd has increased my interest.

    I have been unable to find a registration link to receive your newsletter. Even when a try to log in failed there was no link to registration.

    I would very much like to receive these articles by e-mail
    Cheers, Doug

      Hello Douglas,

      We don’t exactly publish a newsletter anymore. Dennis started The Hollow Earth Insider as a newsletter, yes, but it is now uniquely a web news site (with the world’s best newsletter archive about Hollow Earth under the heading “DEEPER”). There is a collection in there exceeding 550 pages of the old THEI newsletters. If we ever manage to resurrect the old forum as well, it will exceed 4500 pages.
      We do offer a notification service for when something changes on the new site (normally, that’s around a half dozen to 2 dozen times per day). Directly below the “donate” button in the right column, you can sign up for change notices delivered in your email. It’s private and secure and will let you know when new stories or comments are added.

      I hope you continue to enjoy both the content and the intent of The Hollow Earth Insider.

      Rick Osmon

    John Lear has appeared on https://www.coasttocoastam.com/shows/archive several times.

    On the June 28, 2015 episode (see link at top), he talked with host George Knapp.

    Lear said that some of the underground military bases ( http://www.sauderzone.com.ipaddress.com/ & http://www.angelfire.com/ut/branton/redbook1.html ) go down – with elevator acess – 15-20 levels, and in some cases even more.

    Lear also said that the the U.S. Navy ( https://www.amazon.com/Secret-Program-Extraterrestrial-Alliance-Programs-ebook/dp/B01NAS4M58 & https://noriohayakawa.wordpress.com/2016/02/16/the-secret-group-com-12-in-1992-fact-fiction-or-disinformation/ ) has been able to navigate – using nuclear submarines – A HUGE UNDERGROUND NETWORK OR LABYRINTH of MASSIVE aquatic (WATER-FILLED) caverns and tunnels, which reach beneath AT LEAST 15 WESTERN U.S. STATES ( http://www.theeventchronicle.com/study/john-lear-navy-submarine-base-nevada-desert/ & https://www.bibliotecapleyades.net/sociopolitica/sociopol_lear03c.htm ).

    Are there also similar caverns ( http://www.angelfire.com/ut/branton/CaliFloats.html ) in the outer/lower slopes of the continental shelves of the EASTERN USA?

    Will the definition of the Navt S.E.A.L.(S) possibly one day in the future be changed to: S-ea, E-arth, A-ir, & L-abyrinth? Also, do these oceanic caverns reach to the area beneath northwester New Mexico? (see: http://www.angelfire.com/ut/branton/DulceMatrix.html ). If so, the Navy Seal’s and other Special Forces may be able to finally purge one of the darkest areas beneath the surface of the USA.

    Here are some more sources related to the above revelations:
