Cave Shaft at Twin Trickles – exploring rocks and minerals from within (Bancroft)

Cave Shaft at Twin Trickles – exploring rocks and minerals from within (Bancroft), originally uploaded by Mic2006.

In the Fall 1998 edition of the Canadian Caver, Brad Wilson relates an interesting experience that he had while exploring a remote cave in the Canadian Shield. He says that he could see a small room beyond a horribly tight squeeze so instead of going face forwards like he would normally do, he went feet first and after a little struggling he suddenly slipped through into a tube – chest deep into icy water. As Brad points out, to have gone head first would likely have been the end of him.

Exploring the rock from within, as we did at Twin Trickles Cave was certainly an amazing experience. The marble and calcite was incredibly sculpted and at the bottom of the shaft pictured above, there was a room that was bowl-like, and entirely striped black and white by the surrounding rock. When I mention a cave in the same sentence that I mention Bancroft, I do not for an instant suggest that it is a site for rock and mineral collecting. Caves are natural wonders that have been thousands of years in the making. They should be left exactly as they are found.

Check out this video documentary of exploring rock and minerals from within (Bancroft) here.

Twin Trickles Cave is some short distance into the forest and on the day that we visited, it was horribly inundated with ferocious black flies – food for the bats that reside within. although Twin Trickles is not a large cave, the rooms are sizeable for Ontario and there is a long tubular tunnel that seems not to have been followed either by ourselves or Brad’s group in 1987 – obviously it is no easy task and it dips down toward the water table. There are plenty of unprobed leads in the area of Twin Trickles so there will be more trips up in that direction this coming summer.

Embryo Cave, a cave in marble near Toronto

Embryo Cave, originally uploaded by Mic2006.

JC and I spent the weekend at one of our favorite northerly destinations exploring both Embryo and Twin Trickles caves. Both these caves are seldom visited and if it were not for the initial visit by Marcus and Brad they likely would be entirely forgotten by now.

Both Embryo Cave and Twin Trickles are marble caves at the edge of the Canadian Shield (near Toronto Canada), but they are very different in character.

Much as you might imagine, Embryo Cave is a cave that is smooth inside, easily traversed, the long borehole crawl being in soft silt, while Twin trickles is a cave in which you shred your knees, cave suit and anything else on or around you. The rock in Twin Trickles is sharp and jagged, the cave dips quickly downward through jagged portals and though the marble is beautifully banded there is more a feeling of intimidation in this cavity, it varies between tight and spacious, dry and soaking wet, jagged and more jagged, with lots and lots of black flies – see video on Embryo Cave here.

Precambrian Marble Cave

IMGP1872, originally uploaded by Mic2006.

JC and I have a lead on a Pre-Cambrian marble cave that we will be exploring on Thursday. Most exciting is the fact that the area is host to several known tunnels – they are small but beautiful and where there are some, there are more. Best thought in this area will be to speculate on what is buried. The surface geography will be our initial clue, we will be looking at unexplained dips in the soil, sink points and resurgences, contacts between marble and granite, and possible funnel points that have been created by glacial erosion.

Either way there will be some good pictures of the known cave (assuming that we can find it) and hopefully we can find something else in the area that presently lies waiting for us to discover it.

The Newt of ‘Noot’s Nook’ – A Documentary Video of Cave Wildlife in Ontario

The Newt of ‘Noot’s Nook’ – Cave Wildlife in Ontario, originally uploaded by Mic2006.

It’s hard to imagine how thrilling it was to see this wonderful yellow spotted newt. He crawled out from beneath a rock as we were digging in Newt’s Nook, a local cave near Toronto (Ontario).

Newt’s have both a terrestrial and aquatic phase to their life, they hatch from eggs at a length of about 1 centimeter and they exist on land, hiding beneath leaves and old logs. Officially a young land-dwelling newt is referred to as an ‘eft’. After about 3 years the eft moves into a swamp to continue the remainder of its life (about 10 years), flippering about in the mud and slime.

I am thinking that maybe the yellow spots have something to do with warning other animals to stay away. I understand there are toxins in the newt’s skin that make them poisonous to everything but a garter snake. Apparently there is a ploy whereby a beleaguered newt flops over onto it’s back to display a belly that reddens in proportion to its anxiety – another form of warning. Once transplanted from the spot beneath the rock that we found it, the newt blinked myopically and then began dragging its feet in a slow but persistent dash for the nearest crevice.

See this documentary video of our dig at Noot’s Nook and the discovery of the above pictured creature – here.

Our intention is to return to Noot’s Nook and continue following downward toward tunnels that appear to exist about 3 feet beneath the solid base of the cavern in which we found the newt. It is possible to see the space below through a narrow crevice. However great our excitement, we must exercise care as safety is paramount on any dig – especially where there is so much loose rock.

At the bottom of the sinkhole; A deep mysterious pit in Ontario, Canada

At the bottom of the sinkhole; A deep mysterious pit in Ontario, Canada, originally uploaded by Mic2006.

This weekend Jeff and I descend to the bottom of a cold and dripping sinkhole in Ontario, Canada. It would appear that most are unaware of the existence of these pits, thinking that they only occur in Florida and other places where there have been some well publicized swallowings of people and posessions. Sinkholes occur for several reasons, but in stable rock they develop slowly and predictably over thousands of years and it is only the careless who end up lying broken and dying at their bottom.

In Toronto, it is most likely an underground pipe that has broken and eroded the lake deposited sediment beneath the city streets that would pose a sinkhole hazard. On rare occasions there have been collapse windows that have unexpectedly appeared in farmer’s fields, and of course there have been the celebrated cave-ins around mining communities like Cobalt and Kirkland Lake that have resulted in the loss of buildings. I believe it was in Timmins that a school bus was swallowed up one night with a sleeping beggar who had sheltered there, little suspecting that he would wake up entombed within the earth.

See the Documentary video on the sinkhole that we had explored this weekend – a Deep Mysterious Pit in Ontario Canada – here.

I spend my weekends caving and it appears that for the scarcity of horizontal cave openings near Toronto, it is now the vertical shafts that we are breaking open in hopes of exposing buried tunnels. Pictured here is one such shaft that sinks deep into virgin rock.

Disaster Documentary on the Niagara Gorge Railway – Wrecked train found while hiking along the Niagara River (Niagara Glen)

Niagara Gorge Railway – wrecked train, originally uploaded by Mic2006.

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.

What to do on a Winter Day in Toronto Canada – Video on Ice Caving Adventure (Toronto University)

What to do on a Winter Day in Toronto, Canada, originally uploaded by Mic2006.

The above picture is of the inside of Travertine Cave, which is situated at location near Toronto, Canada. We visited one winter day quite recently. While at University I often remember sitting there wondering what I could find to do aside from studying (of which I did precious little) (Toronto University, or possibly University of Guelph, or McMaster University – Hamilton, are close to here).

In the accompanying video – What to do on a winter day in Toronto Canada – Ice Caving Adventure (Toronto University) I detail my attempts to explore the cave and the unfortunate accident that I had which now leaves me aching and bruised.

Of particular interest was the observation that deeper into the cave – well past the flowing water at the entrance, was the realization that water was also flowing outward from within. I had always thought that Travertine Cave was simply a shelter that had formed as Tufa seeped over the edge of a low cliff. Water flowing from within might suggest the possibility of a solution cave and tunnels that are more extensive than I had imagined.

The ice formations in Travertine Cave were also very unusual. A strong breeze blows through the cave and the resulting icicles are flat and bladed with square protuberances at the bottom of each hanging pendant. I am left wondering what freak of climate or geography would so consistently create that unusual shape amongst not one, but all of the icicles hanging in a certain area of the entry grotto.

Winter hiking near Toronto (Behind an Ontario Waterfall in the Winter – on the Niagara Escarpment)

Winter hiking near Toronto (Behind an Ontario Waterfall in the Winter), originally uploaded by Mic2006.

Some time ago I did some winter hiking near Toronto (Niagara Escarpment) and explored behind a waterfall to see how it would look with all the icicles. Needless to say it was amazing – exceeded my most hopeful expectations. Most impressive was this low rumbling sound that filled the whole cavity, it was a new dimension to my unusual Ontario based travels – sound.

Check out this video of behind an Ontario waterfall – here.

In line with the publication of my first book in 2005 (Rockwatching), in the video that I have linked to just above, I show a little bit of the local rock and the contact between the Queenston Shale and the Whirlpool Sandstone.

Secret Tunnel to Dracula’s Garden – A Hidden Passage takes us to a Secret Room

Secret Tunnel to Dracula’s Garden, originally uploaded by Mic2006.

Leaving from Jeff’s house in Guelph, the three of us braved the winter evening and followed a secret tunnel to a place that is known as Dracula’s Garden. The garden is really a secret room beneath a city in Ontario. The trip there and back was exhausting. We were underground for just over 2 hours, crawling, duck walking and stooping. We waded through an old and crumbling passage that is known as the blood sluice – and at the end, a most incredible place that is decorated in soda straws and various other formations that are usually found in caves.

See video on the secret passage to Dracula’s Garden here

Jeff found a strange green marble that we called the “Dracula’s Eye” and SNAFU discovered a symbol part way along the hidden passage that was etched into the wall; I say it is for the Illuminati, but that is only wild speculation.

Most intriguing about the speleothems in Dracula’s Garden is the fact that they have formed so incredibly quickly.

Soda straws, curtains and stalactites are composed of calcite that has been leached out of the soil and rock above and re-deposited within an underground cavity. The basic process is that carbonic acid dissolves the calcite as acid laced ground-water passes through calcium rich substrate. Cool temperatures, lots of water and the presence of organic matter adds to the concentration of the acid. By the time the carbonic acid rich water reaches an underground cavity, and is is heavily laden with dissolved calcite, it gases off carbon dioxide and becomes super-saturated with calcite, thus it dumps this at the edge of a speleothem and grows it as some fantastic lacy rock pinnacle or curtain or cave pearl.

In Dracula’s Garden the speleothems have grown with amazing rapidity. Decorations like those seen here are usually thousands of years in the making, these formations are pure and white and hard and yet they could not be older than the cavity in which they’ve formed – about 100 – 160 years in age. Conditions for speleothem growth must be ideal. I had once seen a single soda straw in a sewer in Hamilton  (Stairway to Paradise), but it was puffy and porous – more like tufa than the pure and well formed soda straws in this spot.

Two hours of crawling and duck-walking leaves my legs in agony today. I can barely walk and I’m sure my companions are suffering some similar pain as well – SNAFU more his knees being a problem as being the tallest he found the height most dehabilitating and he crawled more than duck-walked. In the video you can hear this strange whump, whump sound in the background, that’s him crawling in his hip waders. As it is now dark I think a little hot tub therapy might ease the pain – standing after sitting is the worst and going down steps is almost impossible (I have to go down backwards on my hands and knees).

Caves near Guelph, Canada

Caves near Guelph, Canada, originally uploaded by Mic2006.

Jeff and I believe that this small group of shelter-like caves near Guelph, Ontario, Canada might well be the resurging exits to a system that slopes downward from the river valley along the bedding plane. It appears that from the visit that we made, the tunnels all slope downward and are soon filled with clay and gravel.

See the video on a few areas that we were looking at here

It appears that since our visit the previous weekend, the ice crawl into the #8 cave has got significantly tighter. The February thaw and then flash-freeze has almost closed some passages in places. I vaguely entertained the thought of the tunnel freezing shut behind me. That would be a nasty way to die, especially considering that lying on the ice, with my coat pulled up from my stomach I was getting a taste of how it would feel to be slowly freezing.

Anyway, we did find a spot with blowing air on our previous visit and we also saw 2 likely spots where digging might open further passage. I am reminded of the dig and railway system that I had once seen in the Cheddar Cave. Eventually those cavers reached the river Axe and from there some incredible stories of underground and underwater exploration.
