Caves: The World Beneath the World!


If you are stretched and squeezed by everyday life, then you might be in perfect shape to explore caves.

Enter a narrow natural passageway that may lead to simply mind-boggling underground world. Caves may lurk right under your feet: a fascinating and unexpected environment, which is often known only to spelunkers and dedicated Gollum-seekers.

Back to the Cave!

"Symphony of Stones" (how aptly named) -

Fairyland Cave Formations

Caves are a fairyland of delight, from the burning hot enclaves to the glacial ice mazes. Thousands of years of dripping water, eroding stone and budding minerals create a silent world of mystery and beauty... Graceful arches, giant crystals... silent but for the sound of water dripping and bubbling through.

The most common type of caves form when slightly acidic rainwater trickles into the crevices of limestone and gradually widens the cracks as it dissolves the stone. Centuries of water, supersaturated with minerals, dripping from cave roofs cause stalagmites and stalactites to form (see here).

One thing to keep in mind during cave exploration: though these structures are made of minerals, they are generally extremely thin and fragile, many of them are quite rare, and can be damaged or destroyed by touch alone. Calcite (the mineral which forms many cave structures), for example, is soft enough to be scratched by a fingernail.

Some of the cave and rock formations:
- Flowstone (also known as a Bacon formation)
- Cave Pearls
- Soda Straws
- Helictites
- Anthodites (or Aragonite)
- Bottlebrush formation

Probably the most comprehensive cave-exploration site on the net is that of Dave Bunnell... You can spend hours there, wandering around pages, cataloging whimsical underground structures, oozing rock and dripping stone.

Largest Cave Systems

We mentioned the Jeita Grotto - the largest cave system in the Middle East- in our recent Lebanon article. The longest known stalactite in the world is found there at 8.2 meters long.

- The deepest known cave is Voronya Cave in Abkhazia, Georgia and has been explored to a depth of 2191 meters.

- The longest continuous cave system yet explored is Mammoth Cave in Kentucky, covering 591 kilometers.

Let's have a short world tour of the most interesting caves, why don't we? We'll start with North America -

Already mentioned Luray Caverns in Virginia are full of celebrated speleothems formations, calcite crystals of abnormal shapes - all formed when the chambers were completely filled with water, highly charged with acid. The acid began to eat away the softer material, resulting in ornate pinnacles and arches...

One of the deepest known cave pits, Fantastic Pit in Georgia's Ellison's Cave descends 586 feet (179 meters) in a straight tunnel:

Glacial Caves and Ice Caverns

Some ice caves must rather be called "glacier caves", which can simply astound with the intensity of ice color:

Here is a wonderful page of ice caves photography by Jason Gulley:

A lot of ice caves grow "hair" - ice extrusions, some are quite strange-looking:

Brazil: Crystalline Underground Waters

Mato Grosso do Sul region in Brazil (and especially the quiet town of Bonito) boasts many marvelous underground lakes: Gruta do Lago Azul, Gruta do Mimoso, Aquário Natural. Intricate limestone formations and grottos hide the intensely-colored pools and waterfalls (many adventure tours there feature diving, some pools are more than 100 meters deep):

Venezuela: Cave of the Ghost

Cueva del Fantasma is big enough for two helicopters to fly into it, but it's not technically a cave - rather, a collapsed gorge. It does, however, sport a huge waterfall right inside of it:

Iran: tremendous cave system

Katale Khor is a cave dating back to the Jurassic period. It's one of the "snow caves" in the Southwest Zanjan province and connects to other caves - a huge underground infra-structure which can hide who knows what (definitely anti-American... wink wink). See more pictures here\

Can't get enough images of Iran's natural beauty? See our previous articles... a country full of great sights and dubious politics.

Vietnam: Hang Thien Cung cave

There are plenty of caves in Vietnam, and just like in China, many are illuminated with garish colors. (see here). But sometimes even artificial light takes back stage to the incredible rock textures:

Mexico: Giant Selenite Crystals!

In 2000, one of the most unusual and splendid caves was found in Mexico by miners. Located only a mile from an upthrust of magma, this cave is 112 degrees Farenheit and at 90-100% humidity, limiting greatly the amount of time explorers can spend in it. It is a spectacular cave, with gigantic crystal formations thought to be 600,000 years old.

The crystals formed underwater; as water saturated with calcium sulfate heated in the cavern selenite molecules crystallized and grew, undisturbed, to giant proportions. The cave was drained (by unknowing miners) in the 1980's and stopped the process of growth. Who knows what we may find further on, in the heat and water?

A description of one photographer's attempt to document this cave is here.

"It is unquestionably magical that the cool white rays of moonlight can originate deep underground in a black chamber that is, at least in my perception, white hot." (Richard Fisher, photographer, comments on the huge selenite crystals.)

A Giant Geode


Geodes are normally formed by volcanic or sedimentary geologic activity - a cavity in the rock is formed, inside which crystals begin to grow, such as amethyst, quartz or a number of others. Most geodes are small enough to fit in your hand, but this one is large enough to climb inside. The crystals found here are gypsum. - More info.

The largest Geode Cave in US is located in Ohio: Crystal Cave, check it out.

Ancient Cave Cities

Khosrov Caves in Armenia served as a shelter to ancient tribes - in a perfectly cinematic location:

We wrote about Cappadocia cave city in Turkey before. But you might not be aware that more modern establishment makes its home there - a luxury hotel!

Caves: The World Beneath the World!

Considering how hot it can get outside, it definitely provides a welcome coolness:

This PC case mod would fit right there, in that cave hotel room:

Then again, there's a wildly original Stockholm subway station, seemingly built inside a natural (in reality - blasted) cave :
