There's hundreds of hits on the WEB using SPELEOLOGY as the
search word. One such search takes you directly into the
NATIONAL SPELEOLOGICAL SOCIETY homepage where there's a
lengthy list of members; the organizer of the homepage is
[log in to unmask] if you can't get into the WEB;
[not certain about upper/lower case letters of this
address].
My understanding is you must be a member of the NSS or other
caving organizations such as the International Union of
Speleologists to explore many caves. Speleologists are a
tight-knit group who are extremely secretive about their
caves. - PML
