The Niagara Gorge is rich in history. From the disasterous assault by American militia on Queenston Heights to the geological record in the Gorge’s rock there is no shortage of things to see and learn about.

Of particular interest to me was the story of the short and disastrous life of the Niagara Gorge Railway. It runs along the bottom of the American side, just above the river. It is said that the construction was the most costly stretch of railway ever to be blasted. And not only was the line costly in money, but there was a heavy price in human life as well.

See the documentary video on the Niagara Gorge Railway and the wrecked train that we found while hiking along the Niagara River.

Amongst the more memorable disasters for the Niagara Gorge Railway were the sewage pipe explosion beneath the tracks, where passengers were showered in raw sewage, and there was also the huge landslide that killed 9 people. As mentioned in a coment about a recent accident in the gorge, NenaSan says, “The Gorge is a beautiful but unpredictable place that needs to be both feared and respected”. true enough, several helipads are marked out beside Devil’s Whirlpool for the recovery of injured hikers and the all to frequent bodies that are fished from the river.

Pictured above is the boiler of an old train that we found while hiking in the Niagara Glen. It lies beside the Niagara River just across from the spot where the landslide wiped the Niagara Gorge Railway from existence – oddly, I suspect it might not have been the train that was used on that line.

Waterfall in cave, originally uploaded by Mic2006.

I suppose on of the most gratifying things about cave exploration is the ‘buzz’ that you get, and everything in existence seems to be encompassed in the yellow circle of your headlamp. Outside your headlamp there is mystery – turn your head and the mystery reveals itself. Each turn, corner and passage feels like it’s own first time discovery – I guess its something like the gambler’s buzz, and once you leave the cave the buzz dies away and then I feel like i’m in this slump and the rest of the week is grey and gloomy.

First human in a place that has lain untouched for several thousand years – beat that! How can you? The greater the challenge, the more the buzz. If somebody has already gone before you and poured a concrete sidewalk where’s the wonder there? I believe caving can become an addiction, and having caved for 26 years now I am hooked just like a junkie. And oddly I’ve become a connisour of rare and unusual sights – a flowstone dam, cave pearls, speleothems and speleogens, crawling in tunnels that are washed by frigid streams, deep tannin stained pools in marble, dolostone, calcite and limestone – privy to a sleeping porcupine’s bedside, wondering if a bear lies just beyond. Where does the waterfall come from? What wondrous crystal is that? some would pay a fortune at a mineral show, I prefer the mineral exactly where it sits – a concept of eco-mineral exploration which is something quite closely allied to ethical cave exploration.

See my latest cave trip here to the incredible beauty of Marvin’s Cave and its mysterious tunnels through marble beneath a forest escarpment.

I’d have a problem topping this discovery – Mountain River Cave here.

I am by no means a professional rockhound. My education is as both a gemologist and a geographer, but I believe both rockhounding (collecting minerals) and my other great interest – caving have been in my heart since childhood. And where better to rockhound than Bancroft, but a word of caution, as both rockhounding and caving appear on my site. Both activities are related to rock, but neither should ever meet. Cave mineral deposits must stay in the caves and a caver who shares both interests (and there are many) should never let their inner rockhound loose beneath the surface.

Wearing my rockhound persona this past Saturday afternoon I headed out to the Bancroft Chamber of comerce to get a vibe on the local collecting possibilities. For a place that styles itself as the mineral capital of Canada, they do very little to encourage that reputation. Remembering back to my childhood, rockhounding was everything in Bancroft – now it is just faded memories and hanging onto loose and fragile threads. Fortunately mother nature takes care of basics and continues giving back. I left the Chamber of commerce disillusioned – not by the staff, not their fault, just the general malaise of the people who call the shots. No effort to justify the reputation.

Anyway I picked up an ice Cap from Tim Hortons and headed off on a kind of aimless ramble, and within about half an hour I’d come upon a spectacular crystal vug (cavity) from which I spent the next few hours scooping crystals.

The cavity is shown in my video – Click here for Crystal cavity in Bancroft video

It was a calcite seam within a road cutting that had been opened by someone else and then abandoned as they obviously did not know what they had found and if they had looked within the cavity when they hammered it open it would be they not me who was posting the pictures.

My point is, you just need to know what to look for. Bancroft is famous for its calcite intrusions, a mineral that solidifies last from molten rock and so it acts as a medium for other minerals to grow in. The vug that I extracted crystals from was predominantly filled with amphibole and feldspar crystals and lying loose in the bottom of the part of the cavity that I dug into were a few doubly terminated crystals – having grown in the medium as opposed to being attached to the cavity wall. In retrospect, looking at the video it becomes obvious that the seam runs on an angle and there is likely to be a lot more to be extracted if rockhounds just follow up and down along the incline of the seam. As this rock cut is in a public place I will just leave its exact location for you to figure out, but there is enough in what I have said and shown on the video for you to quickly pin-point the general vicinity of the deposit.

As I am still recovering from my mexico trip – (a nasty ailment that leaves me wishing that I’d been a little more cautious in the cenotes), we thought that we’d take it easy this weekend and though we pass Greig’s cave several times a month, we finally stopped in for a visit. Cost is $10 per adult and there is a nice picnic area, washroom, free walking sticks and the use of a flashlight, having my caving helmet I did not inquire about the cost (of the flashlight rental).

When I was younger I recall seeing that great and tacky classic ‘Quest for Fire’ and so it was with some amount of recollection that I viewed one of the larger caverns and I believe it was there that one of the epic battles between the Neanderthals and the other hairy guys took place. Another vivid memory was that unforgettable scene when the three stone-age morons were sleeping up in the tree and one of them had eaten all the leaves. I believe he was taunting a lion or a tiger beneath when the branch he was sitting on broke.

Anyway, more significantly, after a very interesting trip to Shallow Lake and the observation of one of it’s sinkholes, JC and I donned our packs and helmets and spent a little time looking for evidence of something other than the usual sea cave formative processes at Greig’s. I can’t really be totally sure of what I was seeing, I sometimes like to mull over what I have seen before I come up with a theory. For the most part there is a lot of collapse and evidence of wave action, but there was this one spot where a massive joint cut into the rock and from there a low crawling tunnel branched off along an anastomosing route – quite different from the smooth worn walls in other areas. It may have just been a rotting corroded section of rock, but the tunnels were somewhat regular and unchanging in size and one passage that I should have crawled down further, but was filled with porcupine feces, seemed to be quite promising – not so much for what you could see, but rather the floor was dirt and I wondered if there was anything that could be unearthed with a little digging (like a passage that had been miraculously overlooked). Several people have suggested the possibility of solution tunnels playing a part in the formation of Greig’s Caves – I’d like to prove that theory.

The above picture is of a little squeeze beside a pool. Up ahead JC’s camera on a telescopic extension revealed a small cavern that slopes down to the left with the possibility of further going tunnel, but that is just a guess by looking at his pictures. We both tried fitting through here, but neither of us had either the ability or inclination, but Jeff is strongly considering giving it another try – I believe he will fit. It seems that there are sseveral passages oriented along the bearing of a joint that runs somewhat parallel to the clif face – one is quite long and the crawl was increasingly painful in jeans and tanktop. I hope to prepare a little video sometime later in the week.

All in all, the $10 was well spent. The property is very scenic and we suddenly realized that we’d spent several hours in speculation. Admittedly this is not a wild cave, but it certainly has some interest and who could possibly shun it for the fact that it was the setting of that great theatrical masterpiece of my teenage years – Quest for Fire. If you are looking for a casual outing with your kids, providing you keep a good eye on them as there is plenty of opportunity for injury, this could well be one of the fun things to do near Toronto. This is a good example of what cavers call spelunking. I felt a little overdressed with my helmet, but what the heck.

On the surface it was sweltering and buggy, but in the dolostone rock beneath the water was icy cold and I was plagued by a constant drip, drip, dripping that frequently found my eye.

Jeff, Greg and I had returned to the cave that we had recently found to do some digging and hopefully expose a tunnel that we thought must exist somewhere beneath the choke of branches and leaves.

We were absolutely stunned by what we found in about two hours of digging – mind you my thighs and back are paying for it now. In front of us the tunnel wall fell away and beneath we could see a passage.

See video on Prometheus; cave of the alien – here

Although the tunnel is tight we theorize that this might be a feeder tunnel as the scallop orientation suggests that possibility and also the size of the in-flowing stream also leads us to suspect that we are yet to make the most significant discovery.

We descended by cable ladder into the cave that we call the Death Bell. That morning we had no idea what we would find. My greatest fear was rattle snakes. I have come across the Massasagua rattle snake in caves before, but being in Ontario, we are fortunate that the Massasagua is the only poisonous snake.

We cleared loose rock from the lip of the shaft and Greg joked that it was like an episode from the X – Files where Skully and Mulder found the black slime alien in a cave much like this one.

See video on the Death Bell here.

As we followed into the cavern – down the swinging ladder it soon became apparent that this shaft was like no other that we had visited. You step off the ladder onto a boulder that is perched atop a 10 foot high mound of bones. Some of the bones were those of animals likely thrown in, along with some garbage from a nearby farm, but by the size of the mound you would imagine that it would have taken thousands of years to grow and depending upon the initial depth of the shaft, the pile might go down well beneath ten feet.

A tunnel led off at the deepest point, following downward along a joint. I crunched through a sediment of tiny black nuggets similar in appearance to charred rice. A puff of wind blew from the terminal pinch-point. Possibly the tunnel goes onward, but it has been blocked by the crunchy fill-in. I believe it must be the casings of a thousand years of maggots that have feasted on the ever-growing heap of corpses from fallen animals.

I am optimistic that this is a solution cave as opposed to a sea cave. Sea caves in Ontario; Rover Cave or Grieg’s Caves for example are generally wide mouthed and narrowing like a funnel. This cave seems to have no surface connection but the porthole in it’s roof, and that hardly provides a suitable portal for erosion.

Whatever the case, an animal that falls in to the Death Bell is doomed to a slow and lingering death – there’s no way out. And for a human, much the same without a ladder.

Cave shaft – Canada, originally uploaded by Mic2006.

In the same area where we discovered the Tooth Tube, a cave that we have been clearing of a glacial plug of clay, we have also found numerous deep shafts, aligned along joints they tend to be deep and narrow with fluted sides and moss around their upper lips. To a caver, a cave shaft is generally indicative of something that might be occuring lower down. Often, but not always, the shaft represents the dominant passage of water as it drops beneath the surface, and as Marcus Buck had pointed out in the excavation of the ‘Birth Canal’ at Olmstead in the Eramosa Karst, “Usually if you follow where the water goes, it takes you on to tunnels”.

This particular field of shafts and pits is in an area that is not too far north of Toronto, Ontario , Canada. For a Torontonian I believe it is one of the coolest things to do near Toronto.

The shafts that we found occur in a plateau that sits well above a large body of water and though the local water table is sometimes known to be perched, it would appear that by looking down into some of these holes, it must still be way below the surface. Many of the more slender shafts appear to be relatively debris-free. Wider shafts tend to be clogged with soil and leaves and logs. They can approach a diameter of about 10 feet in width and we speculate that like in the St. Edmunds System, water may have entered the underground at a time when the area was beneath a kilometer thick sheet of ice. As the pressure head built up, the water beneath the glacier was forced down tiny crevices, down to the bedding plane, and then out at the base of the plateau. Most of these shafts are at the bottom of a conical depression of between 10 and 25 feet in depth. In an old manuscript Martin Davis mentions a stream that he had dye traced that seems to take most of the surface water from this area and drains it out at a single point in the cliffs around the edges of the plateau.

Strings of shafts line up along the general orientation of local joints and we intend to plumb the depths of one such shaft this weekend. Our best case scenario is to find an open cave tunnel that requires minimal digging to clear it. I dropped a bolder down one deep shaft where I could not see the bottom and after an impressive pause I heard the muted ‘thunk’ of tin that had been pounded by my falling missile.

In one relatively shallow shaft we have found a crevice that seems to drop down into a water worn passage beneath, that will be our first priority. It was hard to get a good look at the passage as the crevice above still requires some cleaning, but I had the distinct impression it was human sized and floored with cobbles like we found in the Wasteland Waterway – still to be pushed to its endpoint.

For a final look at where we got with our excavation on the Tooth Tube – Click for cave video of the Tooth Tube here.

Check out the shaft at C-H sink, it is also in an area where sinks dimple local fields. Check out a short video of the C – H sink here

This was our third weekend of digging in the cave we call The Toothtube. We suspected that there was a tunnel entrance in a blind valley and in digging in a likely spot this tunnel was broken open. Glacial clay filled the sealed passages to within about a foot of the roof, but with bucket and garden claw we persevered.

Admittedly its nice to open up a passage but our real goal is to intercept the main branch tunnels that we know must lie beneath. It only stands to reason that there must be some huge underground rivers in this area, all the features point in that direction – in particular some impressive shafts that are partly filled with soil, the lack of surface resurgences, the thickness of the local bedding planes and other nearby tunnel systems that stretch beyond the ability of humans to explore them. This lower level if dug out might provide an eventual connection to this main trunk drain.

An unseasonably warm day – early March found JC and I visiting Southern Ontario on a search for abandoned gypsum mines.

Where both the Grand River and the Nith River meet there is the quaint though somewhat aged town of Paris. It has the appearance of having been passed by progress, there are brick and barn board sided buildings in the downtown – somewhat neglected, but full of character. Large mills had once tapped the water power and the mining of plaster of Paris leaves a fascinating terrain of forgotten rail embankments, inexplicable hollows and gullies along the river bank, weirs and beaches where barges once loaded up the chalky material from underground and of course decayed and vine choked foundations.

I was inspired to photograph this backstreet business, ‘The Grand River Experience’ it appears that they offer canoe and kayak rental as well as tours down the river; I believe it was on their website that I had my first glimpse of a riverside gypsum mine – supposedly one of many that are around there. As you might have guessed, there is a connection between ‘plaster of Paris’ and the coincidence of this calcium sulfate material being mined from a conglomerate that underlies the area. It is said that the gypsum comes from Silurian age lenticular deposits on the south east flank of the Algonquin Arch.

Devil’s Cave is one example of a local feature where running water has dissolved away the gypsum and having washed the conglomerate out, there are small cavities lived in by a colony of beavers and decorated by spectacular white speleothems and flowstone.

Having now visited this area several times and followed apparently sure leads, both JC and I are somewhat disillusioned as to the prospects of finding open gypsum adits – though a cave is far preferred. Everything seems blocked up real well (with the exception of a single adit along the river bank downriver from the town). Crossed shovel and pick symbols on a map (available on the internet) generally leads you to a spot where you’ll find an undercut that is pretty much buried in countless tons of soil.

Having long been fascinated by industrial archeology, urban exploration and various forgotten tunnel explorations I’d like to know of where there are old gypsum mines around Paris where an interested person can visit and actually go underground?

Leaded paint rock art circa 1970. Do you suppose the artist was trying to express his inner soul? will this still be here a thousand years from now and what will they surmise of primitive Ontarions?

I found this unique piece of primitive graffiti in an abandoned Mine near Niagara Falls – this at the edge of a pool of water that stretched on into cavernous darkness.  All through the water there are great hand-cut wooden beams and remnants of the previous mining operation and a deflated plastic raft that had once been used to venture deeper in. From past experience this would be the best way to do it as the mud is really treacherous.

Here is another urban exploration in Niagara Falls of a slightly more daring nature.
