Speleology Books

Nanobacteria have been researched by many prominent scientists worldwide. This book looks at the findings of scientists with respect to Nanobacteria and the science of Geology. Nanobacteria, specifically Nanobacterium Sanguineum, have been studied by scientists and medical researchers as they pertain to causing human disease or Pathology as well. Nanobacterium Sanguineum is a Nanobacteria that is approximately 10,000 times smaller than regular bacteria. It replicates from 1000 to 10,000 times slower than regular bacteria as well. It grows in the human system in blood, and has been found by various medical researchers and scientists to cause many human problems. Some of the various diseases that it has either been implicated to be involved with or to cause are: Calcification in atherosclerotic plaque, kidney stones, calcification in the lenses of eyes that ultimately causes "cataracts", soft tissue calcification in scleroderma, calcification in tumors, calcification in arthritis or osteoarthritis and other pathological disease states in humans. These Nanobacteria colonize and secrete a "biofilm" over themselves that causes them to be covered by a calcium "shell". These Nanobacteria are implicated to be the cause of all calcification in the human system that you were not born with, that you subsequently develop as you age. These Nanobacteria are also implicated in causing some forms of cancer and "apoptosis" or cell death. Scientists are now working on ways to eradicate Nanobacterium Sanguineum with prescription medications. Please keep your eyes open for further research regarding Nanobacteria. Try surfing on the web for "nanobacteria". Sincerely, Gary S. Mezo, President of the Academy of Medical NanoScience, Tel:813-264-2241.

For starters I will never look at my mineral collection quite the same again. Dark Life has shown that nanobacteria (only recently confirmed)is the absolute frontier of a new world. Minerals and "life" coexist and the nanobacteria "feed" upon the chemical compositions of minerals. The scientific world will be turned on its' head in the near future as a whole new science emerges. This book is easy to understand for those of us who aren't scientits but who are interested. As one who also has Multiple Sclerosis the possible connection with nanobacteria and mineral plaques in the brain was astounding as I read it.

_Dark Life_ by Michael Ray Taylor was a very interesting book. The author began it writing as a science journalist - having written a previous book on cave exploration as well has having articles published in such magazines as _Audubon_ - but over the course of the two and a half years he worked on this book went from becoming an observer to an active participant, a point he himself made several times in amazement and wonder. Originally he had set out to chronicle what was known about "dark life," microorganisms that dwell far underground or in the deep sea, organisms that derive their nourishment from sources independent of sunlight. These organisms, which have been found in such varied places as salt domes, Antarctic ice cores, and in highly acidic caves, have continually challenged notions of what life can tolerate, organisms so common that they may outnumber surface organisms (indeed Taylor rejected the commonly used term "extremophile" as he believes the term implies that these organisms are a "rare curiosity"). Taylor wrote of the history of the search for these microbes, the personalities involved, and where current research was in the field (as well as possible applications of this research).

Somewhere along the way he became part of the story, as he became the friend and later colleague of several of the researchers he covered. While not a trained scientist per se, at least not in the field of microbiology, he assisted in and even proposed a number of experiments in the search for controversial nanobacteria (microbes with a size of less than 0.2 micrometers, once thought to be too small to be an independent functioning organism or at least too small for a prokaryotic organism, including known bacteria and archaea; not a virus) in a variety of environments, mostly notably Hot Springs National Park in Arkansas. By the end of the book he was regularly exchanging email with researchers, providing samples for them, and even had co-authored a few presentations at various seminars.

Much of the book is focused on personalities - understandable given Taylor's increasing personal involvement in the story himself - though mainly in the context of research on the topic at hand. The main characters (if you will) in the book were Larry Mallory (a scientist who had devoted his career to harvesting and culturing cave microbes in a promising search for a cure for cancer, particularly from microbes from the fascinating Lechuguilla Cave in New Mexico, an interesting place described in great detail in the book), Bob Folk (a colorful scientist who discovered nanobacteria and their presence in a number of substances and had been in the lead in efforts to prove that microorganisms are vital in the formation of travertine in caves and hot springs as well as in some cases at least entire caves and cave systems), and Anne Taunton (an undergraduate student who as part of a NASA internship became embroiled in the efforts to determine whether or not the famed Martian meteorite ALH 84001 contained fossils of extraterrestrial nanobacteria). Others are followed to lesser degrees, among them Finnish nanobacteria expert E. Olavi Kajander, who had done pioneer work showing that nanobacteria may be the possible agents of many maladies such as kidney stones, Alzheimer's, and Mad Cow Disease that involve mineral precipitation in the body. In large measure these and other personalities faced considerable skepticism, criticism, and worse in their studies, as scientists found it hard to accept (in different instances) what was thought of as "impossibly" small bacteria, biological origins for various types of minerals and mineral formations, and the presence of microfossils in ALH 84001. Mallory had to leave his university because he was essentially denied tenure, the administration not believing his study of cave microorganisms important, Folk faced considerable criticism for suggesting that such substances as travertine owed their origins to bacteria, and Taunton (and the team she worked with) had a very difficult time with several scientists - including even her own undergraduate academic advisor - over efforts to demonstrate that the ALH 84001 microfossils were evidence of Martian life or even life of any kind. Although Taylor did a good job of showing the fact there was sometimes intense and even rather personal criticism in science, I don't know if he always showed why people had such a hard time accepting bold new theories. In particular some of the opposition to ALH 84001 fossils was quite heated.

Though much of the focus was on personalities, politics, and the process of research the microbes were much discussed as well, many with bizarre biologies. Some cold-loving organisms were termed "psychrophiles," capable of growth below freezing, at -5 degrees Celsius, organisms that exhibit slower metabolisms at temperatures above freezing and death at anything approaching human body temperature (organisms that for years - like many other examples of dark life - proved difficult to study and culture in the lab). Some organisms found in apparently solid rock two miles deep, existing only on hydrogen and water, have unbelievably slow metabolisms, appearing to divide cells no more than once per century. Though many caves and indeed individual pools in caves produced unique microorganisms there were also astonishing similarities; the closest relatives to some sulfur-oxidizing thermophilic (heat-loving) bacteria from a cave in Kentucky were found to be a sulfur-oxidizing, symbiotic bacterium from a deep sea polychaeta worm, a relationship that has not yet been explained.

At least as far as this reader is concerned Taylor made his case that nanobacteria exist, that they are key in the formation of some minerals and many caves, and I am very open to the idea that ALH 84001 may indeed contain Martian microfossils. I enjoyed reading about the discussions scientists had about whether or not subsurface Antarctic lakes such as Lake Vostok and Jovian moon of Europa might have dark life and hope that both can be analyzed in the not too distant future.

I read this book after buying on a discout shelf in some clearance book seller. It was a pleasant surprise. It, as I wrote in the title, a little heavy on human drama and soap operatic themes. The science behind it is absolutely interesting and has spurred me to read further on the topic of nanobacteria. This is a great starting out book, but not a great book for those reading for the science of it.

This book documents journeys of discovery and transformation at several levels. It documents a journalist's personal journey from observer to active participant. It also serves as a chronicle of the journeys being taken by scientists all over (and underneath) the Earth and across our solar system to obtain an understanding of life's amazing ability to exist and thrive in the most improbable places.

The author starts out as a spelunking (cave exploring) science journalist and ends up as an active participant in the science he had originally set out to cover. In so doing he has provided an interesting mix of observer and participant perspectives. Being a seasoned cave explorer, the author is at home and adept at describing the techniques and hazards of natural laboratories such as Lechuguilla Cave located in New Mexico.

Astrobiologists have found caves to be excellent laboratories for the extreme environments that may be found on other worlds such as Mars. Moreover, the amazing adaptations Earth life has made to these environments also serve as indicators of what is possible in terms of life's ability to adapt - and may be indicative of what we might find underneath Mars. Getting around in these caves is not your run of the mill field trip. Sulfurous and caustic fumes, anoxic conditions, temperature extremes, risk of injury, and a myriad of other hazards all combine to make these explorations something that only skilled individuals should undertake. In so doing, the rewards to the risk takers are obvious - and are thoroughly documented by the author.

There is much more to this book than crawling around stinky caves with excited astrobiologists. There is tedious work back at the lab, and the inevitable politics that accompanies academic life and government-sponsored research. Given that the discoveries being made about life in extreme environments are brushing aside long held views about biology, the politics can get rather nasty at times. The author provides a cogent description of what happens when the politics and dogma of science collide with new data and ideas. As you read this book you can almost hear the old paradigms crumbling as life's very definitions get an overhaul.

In describing some of the research done at NASA on the ALH84001 Martian meteorite, Taylor provides a classic description of paradigm crumbling - and the threat it can represent to the status quo. The events described surround the work of a student involved in a career-making discovery (possible fossils within a piece of Mars) and an advisor who disputes the findings and seeks to thwart her education at every turn.

While not nearly as dramatic, the author describes many other situations wherein old accepted notions about what life is and where it can be found are challenged. As you travel around - and under - the world with Taylor, you learn about life at abyssal ocean depths, within rocks miles under the Earth's surface, in the cold dry Antarctic, within volcanic deposits, and within highly radioactive environments. Such are the abodes of Earth's so-called "extremophiles".

If astrobiologists have learned anything in the past decade or so, it is that Earth life is capable of existing everywhere that it can theoretically exist. Since some of these "extreme environments" may well pass for "normal" elsewhere in the solar system, the chances of finding life elsewhere start to become quite probable. It is that exciting prospect which is woven by the author throughout the fabric of this book.

The author has gone to great physical extremes to write this book - and it shows. If you want a status report on how astrobiologists are using the Earth as a laboratory for what life may be possible on other worlds, this is it. Moreover, if you are looking for proof that science can still be a bona fide adventure in this Internet-shrunken world, then this book offers that as well.

In Tales of Dirt, Danger and Darkness, Paul Steward shows us the intensity, the peril, the exhilaration of subterranean exploration. These tales will thrill, amuse, and frighten--in other words, they do exactly what good stories are supposed to do, entertain and inform.

This book is a must-read for cavers and non-cavers alike, and for adventurers in general (including the armchair variety).

Paul Jay Steward's novel of short stories, "Tales of Dirt, Danger, and Darkness," is a variety show of caving macabre. The author is your host as he appears throughout the book as if to say, "Welcome to my nightmare." Every page is filled with wry commentary and twisted wit as Paul guides you through caving anecdotes and tales that will make you paranoid enough to avoid the dark recesses of your own garage. This book not only held my interest, it also gave me the creeps and made me laugh out loud. I heartily recommend this one.

Although not a caver myself, I certainly have enjoyed the beauty of caves. They have always seemed to have a life of their own, but now, after reading this collection of stories, I see dark and terrifying things in every corner (which is not a bad thing since I love a good horror tale).

These stories truly reach out and grab your heart and give it a good twist. No matter what your views were on caves before, wonderful or scary...you won't walk away from this book and see them the same ever again.

Mr. Steward's book should come with a sticker like a sign I once saw at a cave entrance. "WARNING, ENTER AT YOUR OWN RISK!"

I once enjoyed going into caves. Now I think I'll just be content with the IDEA of going into caves.

Seriously, Paul Steward's stories are intriguing and scary. In fact, the next time I'm with friends at a late-night campfire I'm going to pull out Paul's book and read the one about the two guys who make the mistake of trying to convince a landowner to let them explore a cave on his property...

If you think you like caves, you need to read this book. There are some things you should know...

Outrageous, bizarre and funny, Paul Steward's book, TALES OF DIRT, DANGER AND DARKNESS, transports the reader into realms of terror not often visited. The horrors of the cave world, presented as entrapment and death, remind the reader that, in darkness, the mind is precariously perched between fantasy and reality and between good and evil. The terror of being accountable to the devil is there because of human greed and the desire for fame and power. And Steward often approaches the episodes in this book with subtle humor. We all have our spiritual dark sides, so clearly presented in this book. An electrifying collection of original short stories, and an excellent read!

CAVES: EXPLORING HIDDEN REALMS by Michael Ray Taylor (0792279042, $35.00) provides some outstanding cave shots from caving experiences around the world. The book accompanies a new film 'Journey Into Amazing Caves' which was released in March 2001: many of the hundred-plus photos are from the film and highlight places no large-format camera has gone before.

I am always left breatheless at the majestic beauty of every cave I am blessed to enter. This book gives wonderful descriptions of caves and the pictures in this coffeesque style book are the icing on the cake.

I really liked this book. It has good pictures for people who want to be a cave explorer. It tells you a good description of the caves these people explored. I really liked the fact that they explored ice, water and earth caves. I think students that are studying caves would really like this book

Many of us have probably been very fascinated with caves since we were small children. However, we probably never had the actual experience of exploring caves nor will we ever undertake such a voyage to many of our planet's uncharted regions.

Perhaps, the wisest and safest way to satisfy our curiosity pertaining to the study of caves, or as it is called, Speleology, is to seek out a good reference text. National Geographic Society's coffee-table book entitled CAVES: EXPLORING HIDDEN REALMS, authored by Michael Ray Taylor, would certainly meet the criteria as being one of the most outstanding introductions to the mysteries of the underground.

The tome is the companion text to the McGillivray Freeman Imax film by the same title.
Taylor separates the book into three distinct sections, ice, water and earth in order that we have a general understanding as to where caves are to be located as well as their respective formations. As the author states: "the skin of the world hides many caves. All are profoundly shaped by, and profoundly affect, the nature of the land overhead. Caves are to a surface landscape as veins and capillaries are to a human face-the hidden structure of an inseparable whole."

The ice section introduces us to the caves of the heartland of Greenland where glossy photos provide us with fantastic visual entertainment that convey to us the beauty of these caves as well as the danger constantly prevalent within. Moreover, we are also clued in to the many animal creatures found within these subterranean enclaves such as the tardigrade. It is to be noted that the study of life in caves is known as biospeleology.

Our adventure moves onto to some of the caves discovered beneath the Yucatan or the section dealing with water. One only has to stare at the introductory photos to this chapter and we can appreciate the utterances of the cavers when they assert: "we are amid the wildest scenery we had yet found in Yucatan; and, besides the deep and exciting interest of the ruins themselves, we had around us what we wanted at all other places, the magnificence of nature."

The final stop on our journey delivers us to the caves of the earth where we explore the deepest one in the United States, Lechuguilla located in New Mexico. We also venture into the caves of Tennessee, Alabama and Georgia or as they are termed the TAG region. The spectacular photo of the Lechuguilla certainly reaffirms the statement that "a picture is worth a thousand words."

Enhancing the usefulness of the book are the many articles pertaining to the study of caves that have been contributed by several well-known experts. These short essays also include those of the author, Michael Ray Taylor, who has explored more than 600 caves in expeditions that have taken him around the world.

Bon voyage on your next expedition into the world of caves where all you will need is a good chair and Michael Ray Taylor's brilliant book.

This book is very well written with lovingly detailed chapters devoted to the many splendid cave networks dotted around the world. There's a great section on the flora and fauna of the underworld, as well. I went potholing in Kak Canyon once, and saw a couple of chutney ferrets, all thanks to this book. Incredible creatures - and I wouldn't have known they were there until I read this.

The Longest Cave is a book which will hold you spellbound and wishing it would never end! Roger Brucker and "Red" Watson were young men 50 years ago when they first toured what was then known as Floyd Collin's Crystal Cave. This book is the story of how they and so many others dedicated days, months and years to seek out new passageways deep underground. In the case of Roger and Red, they dedicated decades and continue to work to preserve the very fragile cave environment.

This book has everything that you would want not only in a book but in a feature blockbuster movie! Adventure, Suspense, Humor, Friendship, Excitement, Discovery, Danger, and around every corner lurks the Unknown which would leave any movie-goer on the edge of their seat! All this without the gore and crime which seems to be the standard in so many books and movies today.

I HIGHLY recommend this book for anyone of any age!!! What makes this even more amazing is that this is a true story.

What these men and women accomplished is the equivalent of climbing Mount Everest in the DARK and without ever having seen a map of it! This is the American Dream of hard work, dedication, comraderie, and perseverance.

We have movies of Everest and Space Exploration and I look forward to the movie based on this book!
Without a doubt "The Longest Cave" will far surpass any movie on the above-mentioned topics.

Thanks Roger and Red for an AWESOME book!

This book is the best book I've ever came across! Outstanding adventure of how the World's Largest Cave System ever came about. The discoveries in this book are amazing! Suspence to the fullest! The people in this book who made this discovery should be noted as the best exploration team of all time! I can only amagine the feeling they got knowing they had made the biggest connection in cave history to this day. It would be almost impossible for anyone else to top the discovery in this book. An amazing adventure!! I couldn't stop reading this book over and over. The authors of this book should give the story to Hollywood to make into a motion picture. I could imagine this story making the best adventure movie of all time. Ron Howard or Steven Speilburg should be given a copy of this book! It would be a hit! I wish I had the full video tape of this expidition. National Geographic's short segment in "Mysteries Underground" was a tease. If anyone knows where or if there is such a tape, please post it! This is a must read if you like adventure to the fullest!

If you like adventure, if you like caves, if you like drama and suspense, or if you breath in and out regularly and have a pulse, you really ought to read this book. The story of the years it took to connect the Flint Ridge/Mammoth cave systems, it sweeps the reader into the wonderfully obsessive world of the Flint Ridge Cavers. A great book. Strongly reccomended.

I bought this book about 15 years ago while visiting Mammoth Cave National Park. I still enjoy rereading it from time to time. It is the sort of book one hates to see end.

The book narrates the history of the discovery that Kentucky's Flint Ridge-Mammoth Cave system of caves is by far the world's longest known series of continuously-connected caverns. The writers and their many cohorts are not only daring adventurers, but a collection of cavers who deeply appreciate the mystery, beauty and science of caves.

A very interesting part of the book is the well-developed character sketches of the many explorers, a good number of whom participated in parts of the long, arduous struggle to discover the connections between five different large caves so as to make them one.

The overriding star of the show is the cave system itself, and the book contains many facinating portions about the beauty, danger, wonder, and history of the things found there by explorers dating back to prehistoric Native Americans, forward.

After a frustrating series of events, including an initial startling lack of interest/resistance by National Park personnel, progress begins to be made in leaps and bounds. When the Ohio cavers find that the Flint Ridge system is the longest then know, an effort is taken up to connect it with Mammoth Cave.

In a spine-tingling narrative about going past the "Tight Spot", a very small passage, the cavers eventually make the connection by going down in Flint Ridge and emerging in a well-known Mammoth Cave tourist gallery. The sense of truiumph and relief is overwhelming and excellently captured.

My size and age prohibit me from doing the things described in this book, and I have never done them. But I was captivated from start to finish by the story of these brave, resourceful people and the cave system they explored and charted. It is as if I am there myself.

My only quibble is that the photographs are limited and in black and white, but the excellent descriptive writing overcomes this factor. I love the book. Very, very highly recommended.

Caves have been intertwined with Kentucky history since a man named Houchins chased a bear into Mammoth cave in the late 1700s. Later on, the valley north of Mammoth Cave was named after this early settler, and the ridge north of Houchins' Valley was called Flint Ridge. Starting in the early 1950s a group of cavers began a lifelong ambition of connecting the caves on the northern ridge (Flint Ridge) to the caves on the southern ridge (Mammoth Cave Ridge). Their goal was simple: To map the Longest Cave. This book covers that time. Along with 'The Caves Beyond' and 'Trapped', this book constitutes an informal trilogy about Mammoth Cave. It is a story of determination over hardship, of perseverence over fatigue, of triumph over nature. Roger Brucker and Red Watson write this book with the confidence of people that were there. From the very beginning, their influence on the project helped mold it into what it was to become. We see them age, from young men in their ealry twenties, to grizzled Flint Ridge veterans to seeing their children caving alongside them. There is a real sense of the passage of time here; people come, people go, the cave is eternal. Fiction should hope to be so true. Dominating all this is the cave. It is all pervading. Over three hundred miles of passage lies under their feet, and the reader fells as if he is crawling, climbing and squirming along with them. We feel the explorer's chill they wade through Hanson's Lost River, we feel their pain as they crawl through Agony Avenue. We satand alongside them as they are awed by the vastness and remoteness of Unknown Cave. Above all else, it is the story of the people who explore the cave. For fourty years, cavers have been gathering in Central Kentucky to explore this cave. To mankind, the cave is eternal. We may choos to protect it, we may, in our ignorance deface it. Either way, we live our lives by interacting with it. Or to put it in the books words: "That is where life is, that is where your friends are".

Read this b! ook.

I have had personal experience with Mr. Sparrow and find him to be a very competent caving instructor. His book, which I wish I had autographed, is very insightful. Mr. Sparrow has taken me caving several times and have felt completely safe and at ease as a novice. Highly recommend this book and his caving services.
From the start of this book it gives you the very basics you need to know about caves and caving. Don't go caving without at least having this book on hand. What a guide.

Has anyone ever asked you what caving is all about? Give them a copy of this excellent manual and they will soon know. Has anyone ever asked if there is a book that they can read when they are taking their first steps underground, or on the end of an SRT rope or trying to photograph the wonder of the subterranenan world? This is the book to point them towards.

By turns instructional and inspirational, this manual will instruct you in the basics of all the techniques that you need for underground exploration in Britain and Europe, while taking time out to tell yu how the caves formed in the first place, what creatures you might encounter underground and why you shouldn't break that straw off! If you cave already you will want it as a reference; if you're just starting out it will help you to get the most out of your next training trip/course; if you're introducing someone to caving it will be an invaluable resource of the why as well as the what in a clear and consistent style.

Beyond the basics of clothing, equipment, ropework, ladderwork and moving underground, Andy has included valuable chapters on conservation, speleobiology, digging, photography and an overview of cave-diving (with all the appropriate warnings). He advises you where to go caving, how to find a club, how to evaluate the flood risk - just how to do it really.

Highly recommended for anyone who has ever pulled on a headlamp and doesn't know it all yet.

Highly recommended.

Very seldom do I read a book twice. ENTERING THE STONE is one of those books. Barbara Hurd's reflections seep under your skin and take you places you've never been. It is frightening and revealing and profound. Hurd has discovered that in our deepest journeys a secret space may emerge, a white dog, the shape of emptiness, a spacious room.

It is a strange blessing that I ran across an excerpt of this book online and sought it out. The local library had a copy. I wondered about the experience of a novice spelunking. What I found was one woman's meditation on sorrow and loss and fear and awareness, and how reason and passion, how space and solid, how dark and light criss-cross and make the liminal experiences telling.

Please don't fault her beforehand if I sound too intellectual about it, too. It's a beautifully written exploration of the meaning of life, but it's sometimes very down-to-earth, too.

I'll have to ditto the previous review. As a caver (also one that knows George), the book is good from basics to the higher level items. (I just don't know how anyone could memorize all that symbology though.) Well George, we're waiting on the next edition.

This book shoud be considered a must buy for anyone dealing with cave surveying and mapping.

'On Station' is one of those books that falls into the category of 'definitive work'. Everything you would possibly need to know about surveying underground has been collected by Mr. Dasher in one volume. Written in a clear and easily understandable style, he takes us step by step through the process from equipment needed to the finished map. Then he explains specific and unusual problems the underground surveyor is likely to encounter and the best methods for solving them. His last section is devoted to examining a selection of existing maps and assessing their strengths and weaknesses. Cave mapping can be a real pain, as anyone who has tried it can tell you, but a beautiful finished map is very often worth the time and energy poured out for it. Using the ideas presented in 'On Station' can be the difference between a first-rate map and something that will eventually need to be resurveyed. On Station is the next best thing to having George himself look over your shoulder and is a must buy for anyone considering caves surveying.

Anyone interested in learning more about caves will want this book. It is easy to read, yet introduces cave science (Speleology) in a clear and logical way. Even a layman like me can understand it. It is beautifully illustrated with detailed diagrams and striking drawings.Both cave geology and cave biology are covered. You will find answers to questions like how caves are formed, why some caves breathe in and out, how stalactites and stalagmites develop, what kind of animals live in caves, and why some cave animals are blind. The authors were pioneers in modern cave research. They have spent a lifetime studying and exploring caves, and write about the subject with style and authority. Main sections are: Caves as Natural Laboratories, Origin of Caves, Characteristics of the Underground Atmosphere, Growth of Stalactites and Other Speleothems, Behavior and Products of Cave Microorganisms, Habits of Cave Animals, Evolution of Blind Cave Animals, Uses of Caves, References and Related Readings, Caves in the U.S. Open to the Public, Index. David McClurg, author of Adventure of Caving, a how-to book on cave exploration.

This book is the classic introduction to cave sciences. Written for the lay person, but with plenty of scientific specifics. Caving is a very young science. This book was written many years ago, and much has been added to our knowledge of caves. Every serious caver starts with this book, though.

If you want to know what it is that makes up a cave, get this guide. Included in this book are facts about cave biology, chemistry of the cave, geological assessments that grandly improve your knowledge of the world of caves. Don't believe me? You'll be amazed how many different caves are in your backyard, and you'd want to know what to expect before venturing and exploring it for yourself. Contrary to popular belief, there are living animals that reside where the sunlight does not touch and how simply made or delicate they may be. Not only that, you'll find out much more that is quite intriguing about caves. I understand this is a simple review in comparison to others, in truth here is the reality behind the science.

This book explains the geology and biology of caves, and how they have been used by human beings. The authors explain the details very well, drawing upon lots of interesting examples of caves from around the world and providing useful illustrations, charts, and photographs throughout the book.

In the section on limestone formations, they explain why most limestone caves have been formed by slowly moving water in a thin horizontal zone directly below the water table. They examine scallop formations, carbon dioxide content, calcite solubility and other factors. (Sandstone caves, sea caves and lava tubes are covered just briefly.)

There is some good coverage about water movement through caves, the growth of speleotherms, and how to date caves and cave deposits. There is a table provided that lists the secondary minerals found in limestone caves and the caves they can be found in. You will also learn about cave temperatures, relative humidity, and how different karst formations are related to the nature and distribution of the soil in different climatic zones.

There is also a section about the many cave dwelling micro-organisms, troglobites, and vertebrates. It explains their evolution, adaptation to the cave environment, and how they fit into the food chain.
