Commenter Joan has been getting rather testy, so I’d better continue my account of a visit a week ago to Cameron Cave, which is near the more-famous Mark Twain Cave, a cavern immortalized in the novels of Sam Clemens. Here’s the first post:
A Camera In Cameron Cave
And here’s more, some of which is fanciful, or damned lies, as some would say:
Recently I put up a sign on the Market Street wall of my building:
“Time Travel Tours Into Hannibal’s Past! See Hannibal During Its Industrial-Age Period of Working-Class Prosperity!”
This morning a gaggle of sweaty tourists stood before me in my courtyard, where I have installed the prototype time machine. They were a bit cranky and contentious, especially those with children. It was a hot and humid afternoon.
Some questions were raised:
“I thought time machines were scientifically impossible! How is it that you have one?”
I replied “This is new cutting-edge technology. I was lucky enough to obtain the one Hannibal-area license for this machine from the federal Bureau of Time Management. As the technology is new, the BTM only allows one such license to be issued in each tourist area.”
“Can you guarantee that you’ll be able to bring us back to the present?”
“As long as you stick with me and don’t wander off, I can assure you that I’ll bring you back to the present time. We are only allotted one hour in the past.”
I didn’t mention a recent unfortunate incident — an Iowa family had wandered off during an excursion and I had to leave them back in Civil War-era Hannibal. I can only hope that they adapted to that era!
“C’mon, let’s get going!” I said. I herded the tourists into the bus-like machine and settled myself into the driver’s seat.
As I carefully revved up the time-dynamos I spoke to the passengers behind me, using a built-in PA system.
“Today, folks, we’re headed back to the apex of Hannibal’s commercial and industrial era, circa 1925. Shoes, lumber, and lime provided jobs for many Hannibalians back then.”
The time-vehicle became evanescent and shimmered as it rose through the roof of my building. Soon we were soaring through the sky of another era.
“Down below you can see the enormous shoe-factory complex.” I said in my best tour-guide voice. “Closer to the river notice the sawmills and planing-mills. In these establishments lumber is being processed from logs floated down the Mississippi from Minnesota and Wisconsin. Towards your right, on the south side of town, you can see signs of dusty activity near the top of a ridge. If you listen closely you will be able to hear the rumbly sounds of limestone being ground. The cooked and ground stone will be shipped out of the quarry in wooden casks, ultimately to be used as plaster and mortar in a multitude of developing Midwestern towns and cities.”
I banked the time/air-craft to the right and headed down the west bank of the river.
The hilly and be-bluffed landscape looked hard-bitten and bare, with most hillsides cleared and pastured. In those days the hills were still populated by the descendants of the pioneer farmers, many of whom were poor. Obviously these Ralls Countians were pressing the land hard in order to scrape from it a meager subsistence.
“It looks like I calibrated our temporal destination just right, folks! See that farmstead right on the banks of the Mississippi? That’s Judge E.T.Cameron’s place, and if you look closely you can see the judge’s son Archie driving a herd of cattle westwards into the hills and valleys of the family’s property. See that plume of steam gushing from a hillside? That’s relatively-warm humid air condensing in the chill air as it streams from from a cave-system that no-one has ever explored. Archie told his father of his discovery and the pair eventually pick-axed the opening, making it wider, and ventured into the cave.”
My allotted hour was nearly up, so I headed the ungainly craft back towards Hannibal.
“If you are willing to shell out seventeen bucks, you can take a tour of the cave that Archie Cameron discovered eighty-three years ago. Is it worth the money? I admit that you won’t see the sort of spectacular cave-formations visible in the various Ozark tourist caves, but Cameron Cave has a charm of its own. There is almost no graffiti, and a visit to the cave is an opportunity to visit one of those rarest of Midwestern localities, a place which has been little-visited by people. The cave has been open to the public for only thirty years and it could be considered to be a pristine environment.”
Enough of my fantasy narrative.. here are some more photos and commentary from my visit to the cave with commenter Sarah a week ago:
Cameron Cave is a skewed grid consisting of at least six miles of passages arrayed across nine subterranean acres. It’s a dry cave due to a capping stratum of shale over the layers of eroded Louisiana limestone. The lack of percolating water in the main body of the cave has led to a notable absence of flowstone, speleothems, and stalactites, except for at least one small area.
Sarah and I were part of a group of a dozen or so. We were guided by a friendly man with a shaved head and a salt-and-pepper goatee. He was full of stories about the cave. As in every “show cave” I’ve visited, formations have been given humorous metaphorical names, such as “the Teapot” and “The Devil’s Jacuzzi”. I find this to be annoying, but recognize that it’s a necessary part of a cave tour. Caves are so removed from our aboveground environment, so beautiful yet so alien — I think these jocose names help tourists retain their equanimity and enjoy the experience.
The guide pointed to a gray ceiling layer above our heads at one point. It was dark gray and uniformly flat and I surmised that it was a concrete slab poured over a crumbly section of cave passage.
The guide said “No, no, that’s the shale layer which keeps this cave so dry!”
I said “So that’s why this cave is lacking in stalactites and soda-straws!”
The guide looked hurt. He just works part-time guiding cave tourists, but he was obviously fond of the cave and wanted us to like it.
“Just wait, Larry!” he exclaimed. “There are some really nice formations up ahead!”
He was right — a few minutes later we came across some nice calcite flowstone formations. Forgive me for not remembering their fanciful names!
At the beginning of the tour I felt hindered and constrained by the guide and other tourists. I like to explore on my own and take my time with my photos. The guide evidently picked up on this and he went out of his way to help me take photographs. In this one his hand holding a flashlight ended up in the frame — he was trying to help me locate the scene in my viewfinder:

I was impressed by this surreal scene:

We encountered a few clusters of bats clinging to the cave walls, such as this one:

At one point a moth which had wandered into the cave flew over my head, followed by a bat in hot pursuit.
The Louisiana limestone from which the cave had been carved is remarkable for its lack of fossil marine organisms. The guide said to me “I’ve been through most of these cave passages, and I’ve been lost several times, but I’ve only seen one fossil down here. It’s just ahead!”
We came to a waist-high block of stone which had probably fallen from the roof of the passage thousands of years ago. A bas-relief fossil crinoid was embedded in the surface of the stone. I took a quick available-light shot as we paused to regard the anomalously solitary crinoid:

Were there eras during the vast time-spans during which these marine sedimentary strata were being slowly built up when there just wasn’t much marine life? The common Mississippian limestone which abounds in the Hannibal area is often just chock-full of fossils — quite a contrast to the Louisianan limestone from which Cameron Cave was hollowed.
Someone else had evidently been lost in Cameron Cave. The cave is remarkably free of graffiti and inscriptions, but this one was prominently visible high on a cave wall:

A jagged pillar and some of the other folks on the tour:

Calcite flowstone:

After a couple of hours we emerged into the 12X20 structure which has been built around the cave entrance. The guide said “This is such an unusual group! All of you are from the Quincy-Hannibal area — that hardly ever happens. I think the owners should charge local people less for a tour. You’d be surprised at how many people in Hannibal have never been to these caves!”
I’m not surprised. The Hannibal tourism honchos make little effort to cater to the locals, who are mostly poor and have a bad or indifferent attitude about the whole Mark Twain tourism schtick. As gas prices rise this may change…
The group emerged from the structure into a sunny and humid July afternoon, blinking and squinting at the unaccustomed light, and walked down the trail to the parking lot.
So was it worth seventeen bucks? I thought the fee was a bit high — $12.00 would be more appropriate. It’s unlikely that I will ever repeat the experience, but I’m glad I took the tour once.
