    100 degrees F is nothing! Heck, it's hotter than that for most of the day durung most of the summer here in the 6th largest city in the USA, Phoenix, AZ. (or is it 8th, I guess it depends on who you ask)

    One of my previous (way previous) jobs was as a ramp agent (those guys that wave those orange wands to direct the planes around, and mess up your luggage [most of the times, not at the same time]) at Sky Harbor International Airport. The official temperature for this one particular day was 118 defrees F. We took a thermometer out to the area we were working (underneath, and behind the airplains (mostly 727, 737 and MD80/88 models, so little jets) and the ambient air was over 150 degrees F. The higher air temp was due to the large blacktop surface, and the fact that jet engines happen to put out a lot of heat.

    It was toasty, but did we complain? Heck yea we did! I mean that's freakin hot!!!

    OT: Not long after I left that job, Phoenix hit a record official temp of 122 F. They had to close the airport for several hours because the charts that Boeing and Co. put out for safe distances for takeoff and landing did not go that high. After a couple of million of lost revinue later, the charts were updated.

  • Closing the site to tourists to preserve the crystals (how fragile are they to evaporated sweat?) might make sense if there were something to ge gained by science types in studying them; of course, I can't imagine what kind of long-term research they would want to do.

    Or they could just limit the number of people they allow to pass through there. It's not as if Naica, Mexico gets a ton of tourists as it is, and how many non-locals are going to drive a far ways in order to see them?

  • Entropy. I'd write out the delta-G, H and temperature equations, but they slip my mind right now because I don't have class tomorrow so I'm drinking right now. Real quick: use energy to do work, or else fall apart, or something. Please don't ask me to write the next text book.

  • Every cave and coal mine I've been in have been quite cool year-round. The article doesn't mention why these caves are between 100 and 150 degrees Farenheit 1200 feet below the surface -- anyone care to enlighten me? I'm guessing it's not from nearby magma or crystal vibrations...
  • I just looked up some stuff at Scientific American, and found that temperature in continental crust increases at about 25&degC per kilometer of depth. 1200 ft is not all that deep: 365m, or less than a quarter-mile, and temperature near the surface is generally steady in the teens, so I don't think it's mainly geothermic unless they're near a fault line or volcano, in which case they probably wouldn't be mining there at all. 65.5&degC (150&degF) is roughly three times hotter than it "should" be due to depth, but I can't seem to find a range of temperature/depth scales for different crust thicknesses, just that one figure from SciAm.

    Crystal caves: they're not just for cheesy movies and old apogee games any more!
    Actually, I bet if you could somehow light the crystals in the cave, it would look really cool. It would, however, be a different beauty from the natural one of the cave. Although, ocme ot think of it, without some sort o light, it wouldn't look like anything.

    Not all spelunkers are god's gift to caves. I'm hoping the cave owners will know enough to cordon off areas susceptable to human hand oils, and probably are smart enough to humidify the air in the cave. It's really not rocket science.

  • They've found Superman's hideout! And I thought it was up near the North Pole.
  • I think air conditioning is a BAD idea. Minerals form because they are not soluble in the environment they form in, and they are only truly stable in that environment. You change the conditions and suddenly they're not stable anymore and begin to degrade. That goes for *anything*, diamonds included. Some are just harder to break down then others. If they truly want to preserve these wonderful crystals, I would keep the environment the way they found it.

    And yes, the idea that, absent humans to appreciate it, this whole ball of dirt could be as barren as the Moon, is perfectly valid. Who would give a shit? 'Gaia'? Frankly, I like that concept more than the unexamined and undefended meme that "Nature" is somehow superior if "uncontaminated" by human presence. Check and defend your own damn assumptions, jerk.

  • Huge Natural Crystals Found in Cave

    By Michael Ray Taylor, Discovery News

    Feb. 8, 2001 -- The largest natural crystals on Earth have been discovered in two caves within a silver and zinc mine near Naica, in Chihuahua, Mexico, according to mine officials. Reaching lengths of over 20 feet, the clear, faceted crystals are composed of selenite, a crystalline form of the mineral gypsum.

    "Walking into either of these caves is like stepping into a gigantic geode," said Richard D. Fisher, an American consultant with the mining company to develop the discoveries as tourist attractions.

    Fisher said that most people can endure only a few minutes in the caves due to their high temperatures. The smaller of the two, which is about the size of two-bedroom apartment, is 100 Fahrenheit. The large chamber, which Fisher describes as the size of a Cathedral, is 150 F. Both are located approximately 1200 feet below the surface.

    Selenite in Action

    The mining company plans to air-condition the caves before opening them to the public next year, Fisher said. He adds that reducing the heat gradually will not harm the crystals.

    The largest previously known crystals were found in the nearby Cave of the Swords, part of the same mine system. Some of these are now on display at the Smithsonian Institution. The local government and mine owners hope to avoid removing any of the new discoveries for museum displays or private collections, Fisher said.

    While the mine company is currently limiting visitation of the caves to scientific experts, mineral hunters have destroyed locks and broken into the chambers twice since they were first opened by mining equipment last April. One man was killed when he attempted to chop out a gigantic crystal that fell from the ceiling and crushed him, according to Fisher.

    "We need more onsite protection of mine caves," said geologist Carol A. Hill, co-author of the book Cave Minerals of the World, who calls the new discoveries "by far the largest selenite crystals I have ever heard of."

    Hill applauds the tourism plan. "Without it, the mining company would probably destroy the caves. Museums have enough crystals," she said. "It's important to preserve discoveries like this where they occur."

    Fisher and mine officials will display photographs and small samples of crystals from the new cave at the Tuscon Gem & Mineral Show in Arizona -- which starts today and runs through the weekend -- where they plan to organize a scientific study of the caves to take place in March.

  • Does anyone have a mirror out there ??

  • These are big, but not even close to the largest crystals ever found. Charles Panache (American Mineralogist, v. 17, p. 362, 1932) compiled some then-largest known crystals, including a spodumene 42 feet long. More recent articles have extended the maximum size.

    By the way, someone mentioned pegmatites; it would be very unlikely to get selenite crystals in a pegmatite.

    It's mostly the loss of moisture in the air, and the oils in the skins of people touching the rocks.

    This is why the best caves are well-kept secrets by real spelunker orgs.

    These caves will be "dead" in 20 years if they condition the air and bring tourists in.
  • what I don't understand is, why this guy wasn't at least mentioned in the Darwin Awards. . .

  • (kinda weird)

    As a kid I bought two geodes from the gift shop of the Kirkpatrick Center/Omniplex in Oklahoma City. Kinda cool to a kid, I liked one best since it had a neater crystal in the middle.

    Fast forward a couple of years and one of my teachers had a magnet made from hot gluing a geode to a magnetic disk. The funny thing was it was the other half to one of the geodes I had bought (the one I didn't like as much)!

    Not proud of it but I stole it from her at the end of the year. (Sorry Mrs. Christie!)

  • Please refer to [this post] [slashdot.org], who's author understood what I'm saying.

    So we do what you say: document and study it, record it to pictures and video, and then seal the cave from all humanity.

    Once sealed, *their existence is immaterial*. The crystals could vaporize, and no one would be the wiser; or they could treble in size, and no one would know. No living thing would benefit from their existence... nor would any living thing be harmed by their loss.

    In effect, they become an artifact of history and their present-day existence would be mere supposition and imagination.

    That's infinitely more wasteful of their existence than opening up the caves to throngs of tourists.

    If you really need to get tweaked about something, then please get tweaked about something that counts. There are plenty of things happening in the Brazilian rainforests that are having deep and lasting negative impact on living plants and creatures.

    For starters, you can get uppity about the destruction caused by the rock hounds who are supplying all the new age shops with their "harmonious" crystals. Most of those crystals are obtained through extremely destructive practices. Yet not a single crystal-worshipping purchasers cares to acknowledge that they're supporting the destruction of rainforests. Hypocrites.

  • It's my understanding that air conditioning systems have the useful side effect of also dehumidifying. This is why on many cars, choosing the 'defog' setting to direct air toward your windshield will also turn the air conditioner on, so this doesn't sound like it would be a huge problem. Of course, you'd also want some kind of filter.

    Now, I like free software as much as the next guy, but when the idea is stretched and diluted in such strange manners as this, it just makes me want to dig my fingers up into that space between my eyeballs and eyelids, reach way back there, grab some fistfuls of brain and yank it out as my eyeballs pop out to make way and then dangle by the optic nerves providing a dizzying view of the ground below.

    Wow, sometimes it just feels good to rant. What I'm trying to say is that to express the idea of equal access, you need not reach for an analogy to source code - especially when the topic you are discussing has absolutely nothing to do with software.

    High School Debate Tactic #123.b:
    If you are loosing the argument, call the oponent a 'hypocrite'. This will always discredit their opinions. This will have the added benefit of causing you to not alter your argument in any way.

    As a special side note: Using this tactic to justify *YOUR* overconsumption will only fool other people - *YOU* know damn well what is right, your just to lazy, selfish and self-obsessed to admit it to yourself... its so much easier to insult another persons character then defend your own actions.
  • Who said anything about being 'cosmic', mon?

    My simple point is that choosing the 'destiny' of a cave full of million year old crystals of that size (massive natural beuty) requires a massive amount of ego.. I cant understand what people like FFFish, maybe you, and mining companies think that because they 'discovered' this cave - they get to decide its future. That future is immediate and everlasting, and based on the rarity and intrinsic value in such a site, it should be left alone. Alone as in: Document and study, pictures and video, websites and books. Anything else is exploitation.

    Even 'tourism' would be over use in my opinion... but all things considered would not be that great a tragedy if done properly (the site is maintained as the 'number one priority').

  • Exactly why does the choice of someone else to have kids constitute an obligation on my part to those kids' unborn grandchildren?

    If I understand you correctly, you feel that you have no obligation to future people (you infer excepting your own children). You are obligated because you are a member of a community. You are obligated because previous generations thought about providing for you.
    I've heard a 'proverb', accredited to the First Nations people: "You do not inherit the planet from your father - you borrow it from your sons."
    If you'd like to - you can live your life in pursuit of satisfying your every need, without a care for anyone or anything else... no one will stop you. What a horrible, lonely, shallow existance it will be.

    Wow - do you trip over your selfishness when you walk?

  • I hope they do a careful study of the stability of these crystals before letting people too close to them. Obviously the guy who was killed did something stupid, but it could happen again...
  • So this isn't quite on-topic, but another interesting story involving caves and air conditioning:

    This weekend, I visited Luray Caverns in Virginia, USA. Apparently, the first air conditioned home in the world was built here in 1901. The owner (a retired ventilation engineer) just drilled a hole into the cave, and pumped the cool, limestone-filtered air into his home via a five-foot-diameter shaft. Story here [luraycaverns.com].

  • Just so you can get an idea of how hot it is down there: 100 degrees F = 38 degrees C (rounded) 150 degrees F = 66 degrees C (rounded) and 1200 feet = 366 m 66! ouch!

  • Just so you can get an idea of how hot it is down there:

    100 degrees F = 38 degrees C (rounded)
    150 degrees F = 66 degrees C (rounded)
    and 1200 feet = 366 m

    66! ouch!

  • Anything only has value in relation to sapient beings, as sapient beings are the only thing in the universe that can value anything.

    Now that that's cleared up, you guys can debate what disposition of the crystals is of most value to the only known sapient beings in the universe, humans.
  • Funny you should mention that, because I was just thinking the same thing. Near Natural Bridge, Virginia there is a commercial cave that does just this. It's been a while since I've been there, but I think the name was Endless Caverns or something of the like. Anyway, they've discovered an extremely rare crystal that cannot exist in an oxygenated environment. (It was packed in mud before it was discovered) They managed to construct a glass enclosure that allows tourists to get an up-close view of the crystals while keeping the crystals themselves in near-vacuum suroundings. I'm sure a similar setup wouldn't be to hard to implement for other caves as well.
  • It sounds nice at first, but it may be more destructive than it sounds. I've been spelunking and studying geology as a hobby for several years now, and it is quite possible that the act of opening the caves to the public alone can destroy some crystals. These crystals probably spend the past few million years enclosed in the cave without the presence of light, human contact, or the cooler outside air. Sadly, this alone may be enough to erode or destroy the crystals. I cannot begin to tell you how depressing it is when you're exploring a cave, enjoying the beauty and solitude, only to find that previous explorations have broken pieces off of walls, spraypainted the interior, or left behind trash in their wake. Not only that, but certain types of crystals break down on a molecular level as selenite reacts with oxygen and light that is not generally found in it's natural growing environment. On the surface, it sounds as if the company is taking steps to preserve the crystals for all to see, but in fact they may be slowly destroying them.

    Why? Why would they need to shut down the cave?

    It's not like the crystals, unseen and unharmed by the public, are doing anything remotely useful.

    Other than generating "feel good vibes," preserving the crystals does no good whatsoever. And damaging the cave system isn't likely to be a big consideration, given that it's a *mining* company. Destroying rocks is what they do best.

    I can appreciate, understand and give in to the sloppy sentimentality that's being displayed by so many Slashdotters -- but, on the other hand, I'm also pragmatic enough to admit that if the crystals aren't viewed by tourists, they might as well be chopped up and sold.

    I'd expected some bunch of tofu munching tree huggers would mine the hell out of it.

    Never stopped giving me a good wheeze. "Oh, save the whales! Beach the turtles! Oh, look! A sale on geodes and crystal pendants! I'll drive my Jeep Grand Cherokee that gets 10mpg the 100 miles to buy some!" Meanwhile there are thousands of slobs digging up huge portions of natural wilderness so they can sell these rocks for ten bucks a pop.

    I'm in the wrong line of work...

    At least these are being kept safe (for now). Those pictures looked very cool.

    When I was 6 I found a very light-weight rock on the playground of my brother's pre-school. It couldn't have been more than an inch in diameter. I kept it in my pocket, and the next day I was bouncing it on my desk at school, because it made a neat sound, almost as though it was hollow. One time I missed catching it after it bounced, and it dropped on the floor and cracked. I was disappointed, knowing that it would now not be in a shape conducive to bouncing, which I thought was just great at age 6. Then I looked, and saw what was inside. I had found a closed geode on a playground in Virgina, USA, and of all the rocks there, it was the one I happened to pick up. To this day I have no clue how it happened, but I know that it did.

    The airconditioning must not only lower the temperature of the cave, but must also remove these metabolic wastes, particularly the water vapour.

    Air conditioning tends to do this anyway. When the air is cooled moisture is removed, which is why air conditioners drip water.

    Also, while selenite is not the most durable of minerals neither is it the most fragile in this sense. The much smaller selenites in my personal collection are unharmed after ~ 10 years despite being kept in open cabinets in New Orleans, LA which is not exactly a low-humidity environment.

    In fact, the air conditioning would probably help to preserve the crystals, since the introduction of outside air cannot be undone. By making that outside air cooler and drier any damage to the crystals will be slowed.

    How about if they build glass tunnels through the caves and airconditioned only those while preserving the natural environment around the crystals. That would keep people from going of the trail and damaging crystals. It would prevent the new atmosphere from damaging the crystals. Also it would save a fortune on the air conditioning bill.

    Moderators: Do your worst.. ive got karma to burn.

    You know FFFish - its people like you who are responsible for the mess this planet is in...

    *JUST EXISTING* and knowing that the Crystals are there is 'enough use' for their preservation. HUMANS of every generation feel they have the right to take anything they please with no consideration to the planet or future generations. Why the fuck should this natural wonder be forced to live up to some asshole's expectation of 'something usefull'? Have you no sense of wonder???? These Crystals took millenia to form - through natural processes of the planet - their mere existance should cause humans to reflect on the planet and the natural wonder around us... instead close minded jackasses like yourself spew shit like "anything remotely usefull".

    Give your head a shake pal- 'God' willing - when your long dead and forgotten these things will still be here, despite your arrogance and hubris.

    According to the article, the mining company will install airconditioning to make the caves more tolerable to tourists. One thing they must consider when choosing airconditioning is the effect of a steady stream of tourists through an enclosed space. Humans continuously give off a steady stream of water vapour, carbon dioxide and other metabolic wastes, and this may have an adverse effect on the stability of the crystals. The airconditioning must not only lower the temperature of the cave, but must also remove these metabolic wastes, particularly the water vapour.

    There are ancient Egyptian sites that have been closed to tourists because the water vapour from the tourists was dissolving the relics, which had been preserved because of the dryness of the site.

    I hope the mining company carefully monitors the effect of the airconditioning and tourists on the caves and crystals. They may need to shut down or limit the tourist access if tourism is having an adverse effect on the crystals or cave system.

    It sounds nice at first, but it may be more destructive than it sounds. I've been spelunking and studying geology as a hobby for several years now, and it is quite possible that the act of opening the caves to the public alone can destroy some crystals.

    What, then, would you have us do? Sure, we could preserve the caves indefinately by sealing them up forever. But then they would benifit no one.

    As the article says, the choices, as far as the mining copmany sees it, is tourism and mining. Obviously mining the caves for the crystals in much more destructive than letting people take a look.

    Even saying that we could avoid this dichotomy, what are the alternatives? Just let "seriosu" spelunker down there? That seems rather elitist to me. I'm not a seriopus spelunker, but I have a healthy respect for and awe of mother nature, and to be told that I can't go spreading around my water vapor, only "serious spelukners" just seems wrong to me. Shouldn't everyone be given equal access to the gaves, in anyone is giving access? Then everyone can enjoy them, and some regular guys might become interested in serious spelunking.

    To me, this seems to paralell the ideals behind free software. Everyone is given equal acess to the finite software resiource (coders can only work so hard), and everyone can appreciate it, all in the sense of irony. And if a microsofty can be one over for Linux or BSD, everyone wins.
