|Many of the speleothems are still active; there are water droplets on many of the soda straws
The "Ten Most Incredible Places I've Ever Stood" series has been a series of hard choices. This one made the list because of the shock and the awe, the way the cavern made my jaw drop as I stepped in. It is an experience unlike any other that I've had while underground. There is a difference between even a well-protected cave, and one in which whole areas have never been touched by a human being. The floor of one of the large rooms was covered with mud, and it was clear from the trackway above that only one trail through it was ever made, in order to put in a light source. The rest of the room remains as it was discovered.
|How incredible is it that some of the soda straws that fell are still standing in the mud?
The discovery and visitation of any cave causes irreversible changes. Kartchner Caverns were discovered on private lands in 1974 and the people who found them were concerned about preserving the original cave environment. The cave was at nearly 100% humidity, and opening it to the desert environment would have dried it out. Such changes in humidity can adversely affect life in the cave and stunt the growth and development of speleothems (cave decorations like stalactites and stalagmites). And yet the caves were spectacular. Was there some way of preserving the caves while making them accessible to the public?
There was one catch. Nothing goes into the cave with the visitors. No food, no water, no backpacks...and no cameras. As you might expect, I live for photography and this for me was a hard restriction. In 2005, though, I got the opportunity of a lifetime: as part of a fund-raiser for the park's foundation, they had a photography day, and the National Association of Geoscience Teachers made arrangements for us to take part. I was going to be given access to the cavern to photograph to my heart's content. To be sure, I had to sign a waiver of commercial rights, and the images that you see in this post today are protected and cannot be sold or used in any way.
|Perhaps the most incredible stalagmite/column I've ever seen
I wandered from passage to passage lost in the moment. It was nice not having a guide (staff were stationed throughout the cave to answer questions and keep an eye on things), but it was also nice to be exploring a pristine cave knowing I wasn't doing major damage just by being there. Exploring a newly discovered cave means leaving muddy footprints and accidentally destroying delicate formations underfoot, or leaving trails in the mud. I remember thinking that the experience was something like being in a museum, but I thought that in a good way: the resource was being protected, and yet hundreds of thousands of people could see and enjoy it.
|Some marvelous "helictites", otherwise known as stalactites on LSD.
Flowstone refers to speleothems that result from water seeping out of cracks in the walls of a cavern. Over time gigantic mounds build up that resemble ice cream sundaes. Kartchner is full of spectacular examples.
I'm not sure what to make of the features below. There are some nice soda straws, which are so delicate that they are the first to be broken off in unprotected caves. The spiky things are the beginnings of helictites, which tend to ignore gravity, growing instead under the influence of water pressure from the interior of the "confused" stalagmites.
Below, one can see a spectacular column in the foreground, and some marvelous draperies in the upper left background. None of the features were broken off, and none were vandalized. I can barely describe what it is like being in such a place. Every minute in the cave was precious. I know there is an argument about worrying over technology in situations like this, and that one needs to live in the moment, reveling in the experience of being, but I actually find caves disorienting. Despite all my orienteering skills on the Earth's surface (and people tell me they are formidable) I get lost in caves. I can't remember one room or one decoration from another. Photographs keep me centered, and keep the memories of the moment alive. And I can share them!
I passed a stunning wall of draperies. Time was beginning to run short and I would be needing to leave this fantastical world for the surface before long. I was sweating, dehydrated, hungry and tired. It wasn't difficult getting around, but the humidity gets to you eventually, draining your energy. I started to head for the exit chamber and the airlock to the outer world.
There was one last close-up of a moist, almost glowing surface of some flowstone, and then I was out the door to the world of light and fresh air. The contrast was shocking. Caverns are incredible places, but they aren't really a human environment. I can understand how the first explorations of caverns could awaken our ancestors to the ideas of shadow-worlds with their demons and nightmares. Hell was presented as an underworld of fiery pits and eternal torment. But in a different context, caverns have been a place where dreams come alive. I think of the spiritual awakening of an initiate in a deep cave thousands of years ago encountering the drawn images of animals and people on a cavern wall seeming to run and play in the flickering light of a burning torch. Wandering through a pristine cave in the present day brings us face to face with a fascinating world that is not completely apart from us. The deep hidden parts of caves may not be a human environment, but much of our early spiritual and cultural development derived from living and exploring the outer edges of the underground environment. Caves are places where magic seems possible.
