Geology and stuff...

For many years I have been a rock collector. I have many Geodes and crystals that are very pretty. I bought a crystal from Africa one year that is brown and very large. I also bought a crystal structure while we were on vacation in Arkansas. It is over 1 foot long and about 8 inches wide with many crystal growths coming off of it. I would love to go and to be able to see these caves.

Now, while I was on the net last night, I saw a story that just blew me away!!It is called: Crystal Cave of the Giants - Discovery of the Largest Crystals on Earth They are from a mine called Penoles-Naica Mine of Chihuahua Mexico.

Here are some of the pics from that story:





This looks like something from out of a SCI/FI movie!! It remeindes me of a movie called The Core with Hilary Swank as one of the main characters. The forces that it took to creat these formations are just incredible.

Quote:

"These crystals are probably stable, as the temperature in the cave is over 150 degrees Fahrenheit with 100% humidity. In other words, these structures are enveloped in steam. A human can only function in this environment for six to ten minutes before severe loss of mental functions occurs. Found deep in a mine in southern Chihuahua Mexico, these crystals were formed in a natural cave totally enclosed in bedrock. When I first stepped into the cavern it was like walking into the Land of the Giants. I have often admired crystal geodes held in my hand, but when photographing these unique natural structures it was almost impossible to get any sense of scale. This is a geode full of spectacular crystals as tall as pine trees, and in some cases greater in circumference. They have formed beautiful crystals that are a translucent gold and silver in color, and come in many incredible forms and shapes. Some of the largest are essentially columnar in shape and stand thirty to fifty feet high and three to four feet in diameter. Many of the smaller examples are four to six feet in circumference, have many incredible geometrical shapes, and probably weigh in excess of ten tons. The columnar pillars are at first the most striking shape, but later I noticed there were thousands of "sharks teeth" up to three feet high placed row upon row and dispersed at odd angles throughout the caverns. While some of the crystals are attached to the ceiling walls and floors of the cave as might be expected, some exist in great masses of spikes and almost float in air. These crystals seem to defy gravity, as they must weigh several tons."

I also found some other pics from another site called The Cellar to demonstrate just how big this place really is.






My many thanks goes to Richard D. Fisher Photographer/Explorer of The Crystal Cave of the Giants and Brothers, Juan and Pedro Sanchez for having the foresight to not drill any farther into the caves and for bringing the amazing pictures and wonder to the rest of the world.
