Balance is important in your day to day life. One has to enjoy both the warm sunshine and the starry nights to have a complete day. Life is never about choosing left, right or even straight but rather to chose a mix of the three until you find that perfect place.
Today I headed to the interior of California in anticipation of seeing some of the most spectacular helictities in the country. The caves of the state are known to produce some beautiful, delicate speleothems and helictites are one of my favorites to look at (next to cave pearls, of course!). Black Chasm caverns is one of those such caves that anyone can take the time to visit.
Helictites galore in Black Chasm Caverns. July 3rd, 2011.
The helictites are delicate formations that seem to defy gravity, growing every which way unlike their cousins of the cave (stalactites, stalagmites, draperies, etc). How exactly they form is still debated but it is commonly accepted that capillary forces play a big roll in their whimsical development.

The texture of the draperies here in Black Chasm was quite different than the limestone caves I have been used to. The crystal structure almost looked more like aragonite than calcite. I don’t know why yet, but maybe graduate school will enlighten me. đŸ™‚

Located near Volcano, CA this National Natural Landmark is a pretty inexpensive visit. There are plenty of places to camp near-by, or if you chose to do what I did, is a nice wayside visit on your way to King’s Canyon/Sequoia National Parks. It was time for me to head out to see some of the LARGEST trees in the world.

I was able to see many of the famous Sequoia trees, including the General Grant which is the WIDEST sequoia at 40′ diameter, the 3rd largest tree in the WORLD by volume. and is 1700 years old! A humorous sight to see in this part of King’s Canyon N.P. is the Centennial Stump. It is a tree that was cut in 1875, measuring 24′ in diameter, and shipped to Philadelphia’s Centennial Exhibition. No one believed that it truly was one tree and they proclaimed it to be the “California Hoax”. There is one sequoia that fell many years ago and is now an empty shell that you can actually walk through. That’s how BIG these trees are!

I stayed the night at the John Muir lodge in Grant Grove, and ate at their wonderful full-service restaurant. It was a bit pricey (think $200+ for the night, although it WAS a holiday weekend) but since the campgrounds were first come first serve and all full I was a bit out of luck. Plus, the lodge ended up being well worth it and the nice dinner was a welcome change to my usual camp food.
It’s a bit ironic that I am a caver because I need sunlight like I need water. In a world full of bright, warm sunlight I love exploring the deepest and darkest depths of the Earth. At the same time I love to spend hours basking in the sun, where I feel happy and content with being at peace. I guess that’s my perfect balance. I need the world as a whole, from the deepest, darkest depths to the greatest, brightest heights. I’m going to spend my life experiencing all that the Earth has to offer.
This Grand Adventure is step one for me, what is your step one?

I had spent all of Yesterday (the official Day 34) driving so that I could get to Dubuque, IA to see Crystal Lake Cave. By the time I had arrived it was too late to tour the cave, and I was too exhausted to set up camp for the night, so I camped at a Econolodge in Dubuque. It was the last room available, as it turns out I showed up on the weekend of some sort of biking festival. Pure luck that someone had canceled their reservation is what secured my room at the Econolodge, one of the budget options for the Choice hotel chain that claimed to be smoke-free but smelled of stale cigarettes. Not my favorite hotel, but I was too tired to care at the moment.

Dubuque, Iowa is a river town, situated along the Missouri river as a major port for trade. Between the lead mines (you can visit the old spanish mines in the area) and the major river for transport, Dubuque flourished and looks to be a nice city. It has plenty to do in the area and I’m surprised I had never really heard of it until I started planning my trip…perhaps it’s because I struggle in properly pronouncing it’s name.
Crystal Lake Cave Dubuque, IA June 12, 2011
Crystal Lake Cave is just outside of Dubuque, Ia and was discovered by lead miners who had decided they wanted to find their own mine instead of work in someone elses. They found a cave when they began to drill in 1868. It was opened to tourists in the 1930s. It resides in the Galena Limestone layer, with another layer of Limestone above it, the Maquoketa. Underneath is the Decora LS/Shale formation, and below that the St. Peter Sandstone that we are familiar with back in Missouri.

The cave, when it was original before the miners began exploiting it’s resources, was very small- probably only a few feet tall. It would have been a nice, long, (strenuous) belly crawl over flow stone in it’s previous, unaltered state. The miners enlarged the walking paths so that they could stand up and roll carts thorough the tunnels, so the lower half of your tour route was artificially carved out.

The top half is incredibly rich in speleothem decoration, and most of them are a pure white indicating no traces of iron or manganese have seeped through to discolor them. One of the most amazing things about this cave is that they have anthodites, and quite a few of them. The cave is privately owned, and depending on who gives the tour you might get a different story. Each person has picked up on different bits of information and added their own flare to the tour. If you are the average tourist that just happened to bump into a cave to waste some time, this is fun. If you are a serious caver or geologist, it can be a little funny to listen and censor it in your head.
This isn’t to say it isn’t a good tour- every place has to cater to the audience and do what works for them. These sorts of privately owned caves are businesses, and whatever drives tourism is what needs to be done to keep the cave open. There is a delicate balance that is needed in any sort of natural resource for the public to enjoy and understand. Every National Park and State Park knows this, and they sacrafice small portions of the prized resource so that people can enjoy it while camping, in hopes that they will become educated and inspired to continue to protect it with their tax dollars for years to come.
You know how the saying goes that you have to spend money to make money? Well, you have to let some of these places go to the wayside of conservation to save the rest of it. It’s a fact of business: If people don’t know about it, they won’t want to pay for it.
It’s time for me to head to another cave that has been opened to the public, this time in Wisconsin. I’ll see you there soon.

The damp, earthy smell. The cool, slow moving air. The lights struggling, and failing, to reach into all corners of this limestone underworld. Caves are familiar territory, it feels like home. The tour guide giving the stereotypical “Do Not Touch” speech, the explanation of the twilight zone, a touch rock to “get it out of your system”, and the story of how the cave was discovered. All of these things are in a cave tour, uniting all the caves into a broad category. One of my favorite parts is when the tour guide shows all the visitors what the “Natural Cave Light” looks like, when people gaspy and children hold on tightly to their parents.
To the untrained eye, all caves are the same. They are all damp, dark environments that descend into the Earth’s depths. Of course they all have similarities, they are all called caves for a reason, but every cave is different. They have different levels of speleothem development, different types of passages, different types of limestone or dolomite, and more. Even within the same cave there can be several different broad categories of passageway, and Mammoth Cave is a great example of this.
Mammoth Cave’s passages can be divided into three main types: The large, oval shaped passages developed in the phreatic zone, the large, more angular passages developed in the vadose zone, and the tall, canyon-like passages developed during times of fast-flowing water, often confined by natural jointing in the limestone. On the Grand Avenue tour of the Mammoth Cave you get to see all three.

One thing I had read about, and have studied pictures and specimens of, but never seen in person were gypsum flowers. These crystals “grew” abundantly in the passages that develop in the phreatic zone (The phreatic zone is termed the “unsaturated” zone, the area of the cave that was developed with some airspace still present. These passages tend to have rougher edges, since the water cut downwards as it flowed through these passages). Gypsum crystals, and their more ornate, developed flowers, form best in dry areas of the cave. The passages formed in the phreatic are usually perfect for this, since the water has, over time, found a new passageway deep beneath this one and left it “high and dry”. The crystals grow relatively fast (geologically speaking), as I saw many instances where someone had carved their name into the cave ceiling and the crystals have begun to grow in these cracks, the former graffiti artist’s name forever in the cave as the crystals adorn the scrawl.

The snowball dining room in Mammoth Cave actually has a cafeteria, where people are encouraged to buy (overpriced) lunches to fuel them for the rest of the journey. The snowball dining room is so named because it has gypsum growing in “balls” on the ceilings and walls, making it look like someone has thrown snowballs around in the room. The bathrooms in here use artificial walls, but a natural cave ceiling that just happened to be the perfect height tops off the room.

The next area you will travel through on the Grand Avenue tour are narrow, tall, winding passages that make you feel like you are wandering around the bottom of a steep canyon. The area, much like the rest of Mammoth Cave, doesn’t have a whole lot of speleothem development. It does have a few areas where water is flowing, and a deposit called Martha’s Vineyard, and a few stalactities and flowstone. For the most part, this area is dry.

After the canyon-like passages you will entire an area that is very similar to the Mammoth Passages tour: The big, rounded, open passageways that were formed in the phreatic zone (the phreatic zone is that which is completely underwater, and the passageways indicate this by the way they are rounded, oval shaped- showing that the entire passageway was smoothed by water erosion from top to bottom).
At the very end of the 4.5 hour tour, which gives you a very good workout as you climb up and down hundreds of stairs and steep hills, you enter one of the areas that is rare in the Mammoth Cave system: The well-developed speleothems. This area of the cave is located against a valley, where the sandstone cap is no longer present since it was taken away by erosion. This allows more water to percolate through the limestone, saturated with dissolved calcite, and redepositing on the ceilings, walls and floors.
Mammoth Cave Speleothems on the Grand Avenue tour. June 4, 2011
The Mammoth Cave Grand Avenue tour ends by exiting through a revolving door, used to help preserve the high humidity that is present in this last portion of the cave. While you have just spent 4.5 hours underground, it is hard to believe you have only seen a very small percentage of the cave. There are hundreds of miles of passageway closed to the public, and perhaps even more miles that have yet to be discovered.

Caves are the ultimate “last frontier”, one of the few places on Earth that have yet to be discovered in whole. Each one of these is unique, and you never know what you are going to discover. I intend to collect as much cave experience as possible, which means checking on cave off my list at a time. Everytime I enter a cave I learn something new about them, see something I have never seen specifically before. The subtle differences are beginning to be more stark to my ever-training eye. I can’t wait to see more.
Tomorrow I head back home for a few days, then I will be heading on my Western loop. I can’t wait to see what the caves of the West have to offer me. I have been to 8 caves thus far on this trip…and I have many more planned, and probably many more unplanned, to visit.
Stay tuned!

Tucked away in rural Pennsylvania sits a small cave waiting to be explored, off the beaten path in the bank of the small mountains of Manns Choice, PA. The cavern is a bit difficult to find and is a fairly small opertion, but what you will find in the cave is a geologist’s candy. It is probably hinted at in the name of the cave, Coral Caverns, but what you will find inside are clear examples of a stromatolite coral reef from the days of the Devonian.
Stromatolite in Coral Caverns, Manns Choice PA, May 31, 2011
Coral Caverns is a privately owned cave. Small and quaint, what it lacks in the generic souvenir and touristy type shop it makes up for with an enthusastic cave owner who shows the cave with pride. Coral Caverns has been in operatiohn since 1932, a small cave discovered by accident when a quarry found the opening in 1928. The limestone is vertically bedded here, and the inside of the cave has some very well preserved stromatoporoid reefs, along with a moderate display of speleothems.
Coral Caverns May 31, 2011
The visitor center has several interpretative displays that can help teach about fossils and other cave life, especially helpful for kids who are thirsting for knowledge. The caverns are open on the weekends for the public to tour, so try to plan accordingly, although if you are organizing a group I am sure a quick call to the owner could arrange a tour time that is conveinent.
Coral Caverns, Manns Choice, PA May 31, 2011
Very near the cave is a wonderful state park that has camping amenities, Shawnee State Park . The campgrounds are large and beautiful, offering access to a large lake where you can canoe, fish or swim. The views are beautiful, as you can gaze across the lake towards the appalachian mountains in the distance.

I could go on and on about how beautiful Coral Caverns was, or about the scenery of Shawnee State Park, but I think this is one of those times where the pictures should do the talking. Enjoy!

When you are truly passionate about something people take notice. Everyone that you know, and some you don’t, supply you with more information about the subject of your heart and the knowledge and experience simply snowballs. A wonderful effect of passion, because each day brings something new. In planning my trip I decided a visit to my friends in Canada was a must on my schedule. Shortly after organizing the dates my friends told me of a place to visit that I simply couldn’t refuse. Nestled in the Ottawa Valley of Ontario laid in wait something I had yet to experience: My first Canadian cave.

Canada is a whole new animal for me, and this was my first visit. I was very excited about earning another stamp in my passport, but was disappointed to find that they don’t stamp it when you are crossing via vehicle. The universe didn’t seem to think that was vefry fitting for my picture-taking, thoroughly documenting ways of travel and I heard a loud shot as something hit my windshield only a few miles past the border. Something had slammed into my windshield (that I just recently replaced this year, I might add) creating a rather remarkable shape: A double “C” on the passenger side. My Jeep had, rather unfortunately, been branded with my trip to Canada.

All four of us (or rather 3 and a half since one was an adorable 2 year old) then headed into town where I was to partake of some local cusine before we headed to the caves. We dined at Odi’s King Burger in Renfrew, enjoying some Poutine. Poutine is a french dish, consisting of french fries covered in gravy and cheese. If you ask me, I think it was like a fried version of mashed potatoes and gravy. Delicious.
The Bonnechere Caves of Ontario, Canada. May 28, 2011The Bonnechere Caves. May 28, 2011 in Ontario.
Bonnechere Cave is located north of Algonquin park and is located in fossil-abundant Ordovician limestone. The cave consists of passages, with no large rooms to speak of, and has very little ornamentation. I would place the very sparse speleothem development at less than 1%. This is quite obviously due to the nature of the cave since it has been mostly filled with rushing water in recent geologic times. The limestone of the cave may be older than some, but the constant rushing water that filled the caverns did not allow redeposition to occur in any large manner. The cave passageways are incredibly interesting. They very methodically follow prominant jointing in the cave’s home formation. It seems to be located all within the same formation, the limestone being all of the same type, but I have yet to complete the research to know which limestone this is.
The roaring waters of Bonnechere River in Ontario. May 28, 2011
The Bonnechere river roars past the cave and into one of the natural entrances carved by melting glacial waters. The entrance is best viewed from the other side of the river, where you can stand on the remnants of an old bridge. The water was pretty high today, this area of Canada suffering from the same high waters that much of America is suffering from this Spring.

My visit to this area of Canada was fantastic, especially since I was able to spend it with such wonderful and accomodating friends. Spending time with them and their son reminded me again how precious spending time with friends can be. I loved every minute of it, and it even made me think a second about having kids of my own. The passion of cave geology calls, however….someday in the distant future I suppose. For right now I have many great friends with cute kids to play with and enjoy (then send them back to their parents when they get grumpy! Ha ha!~)
Tomorrow I was to head off on my own again. I was going to miss spending time with my friends, but I had something pretty majestic to ease the pain: Niagara Falls. I’ll see you there, if I survive the barrel drop (j/k).
