The following are passages from various sources that give information on Inner-Earth related mysteries. They may specify the general, although not the exact, locations of the entrances to the caverns:
In July of 1980, I received a letter from a friend of mine, Ed Berg, of Liberty, KY., who claims to be in contact with a race of ‘extraterrestrials’ who gave him the information which I quote from his letter below:
“…According to my friends in space, some bases have been established, some underground and some above ground. There are many types of aliens, many different kinds. Some believe in God, some could care less – just like humans. Did you know the space people also have souls and know a considerable amount about the spirit world? But this is getting off the subject.
“As to the subterranean cities, they do exist… The cities were constructed by a race (or races?) who inhabit them now. This race is very highly advanced and very peaceful.

Issue No. 843 of the newsletter for the HOLLOW EARTH SOCIETY (GPO Box 563., Sydney 2001, Australia) reported the following about a disappearance in an Australian cavern network:
“Dear Members,
“The upper council has instructed me to inform you that, with great sadness, we announce the loss of a third independent expedition by two of our cherished members to the Central Australian Nullarbor cave region which the Society believes holds an entry point to the inner earth continents.
“An investigation was confidentially made. No trace of the party or their equipment, however, was found. We have omitted the names of the members until we can evaluate whether their mission was successful.
“A second expedition will be launched in March of this year with the full back-up of the H.E.S. We have arranged the purchase of sophisticated electronic equipment from the Sony corporation which will keep the council abreast of all details…”
