I know this is a bit off the topic of survey software, but
here is a book you might find interesting. Over a ten year period, three friends
and I put together a book on the discovery and exploration of Lechuguilla Cave.
The book begins with the digging project that opened the cave and covers 10
years of history from the early exploration to the nationally televised rescue
in 1991. It also covers the people, personalities and politics that were an
integral part of the story.
