We hiked through a jumbled terrain of massive slabs fallen from the cliff face and rounded boulders that have been washed by epic wind-spawned storms.

As entrances go these sea caves far surpass others that I’ve seen, though admittedly there are few sea caves to rival Rover’s some distance further along the shore.

In the picture above Jeff and I have been hiking and reached the end of dry land. Further progress would have to be through Georgian Bay’s icy water. What I found most intriguing about Cave Point was its sea caves part way up the cliffs. For the most part it looked like difficult climbing and I’d imagine few if any people have ever visited some of those harder to reach places.

SeeĀ video on our trip to Cave Point (Georgian Bay)

Our initial idea had been to see if we could locate low-lying bedding plane squeezes close to the water line as we are aware that not every opening in this area is a sea cave, there is huge potential for solution caves and as has already been discovered, there are nearby that are intensely decorated with speleothems.

Yesterday was living proof (thankfully), that caving is more about the brain than the body. Branko, Ricci, Jeff and I explored an Ontario cave that has long attracted a certain kind of interested adventurer, but has kept something of its true extent hidden to all but the most dedicated explorer.

Branko – a large man (well over 6 foot with a sturdy frame) squeezed through a tortourous gap that he called ‘the jaw’ to access thus-far remote and difficult terrain.

See video of Branko going beyond the Jaws of Death getting stuck underground, here.

In returning back from his incredible exploration Branko become momentarily stuck underground in a situation that an ordinary person would have found appalling. Again – mind over body, where most would have been contemplating a gloomy future of hypothermia and eventual death beneath a cold, grey bed of rock, Branko found it within himself to think logically and calmly, resting and practising relaxing techniques to ensure that panic did not swell his muscles. As Branko said, “This is between me and the rock”. And in the end Branko seems to have negotiated his way beyond the impasse and returned to the surface unscathed.

What is adventure travel in Ontario is for cavers a regular Sunday afternoon. Rob, Jeff, Jeff and I revisited this marble cave to hopefully explore other, thus far un-visited passages.

see video on Adventure travel in Ontario – Exploring marble caves, here

At this time we have discovered several other likely cave leads in the area, in particular, a sinking stream (thanks Steve M.) with massive potential for tunnels, but unfortunately it will take some land-owner permission and then a concerted effort by a team with capabilities of heavy rock removal.

Within our already visited cave we explored out into the darker nooks that I had missed last visit. We found several going passages. This particular spot as seen above – with the wad of flowstone marks the entrance to a tube that we are yet to explore. Getting to this spot is somewhat disarming as you wade through about 18 inches of water and 2-3 feet of soupy mud. Every step causes the water around you to literally boil with escaping methane. You can feel sticks and branches down beneath the mud and in their decomposition they are releasing gas. I am wondering what effect open flame might have on the journey across the expanse that leads to this spot.

Anyway – distant as this location is from my home in Guelph, it seems to be rife with caving possibilities so the focus for our caving exploits seems to be increasingly concentrated in this area. There are many karst features in the limestone right at the edge of the shield – in part due to the rocks natural suitability and in part due to the acid water running off the shield.

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, 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.

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.

Stone Church 1, originally uploaded by Mic2006.

In 1965 E.D. Ongley produced his much sought after caving manuscript, ‘A Study of Caves in Southern Ontario’. In that work Ongley mentions the existence of Stone House Cave, a tunnel that had been blasted by the railways to drain a swamp that was seasonally flooding the nearby railway. In that blasted tunnel Ongley had found an albino crayfish and he speculated that the side of the tunnel, which had been blocked by a human-constructed rock wall, likely led onto a deeper, natural cave.

In the attached video, see – Looking for Stone Church Cave here, I show the caving possibilities at the edge of the Canadian Shield and I explore the small tunnel pictured above. This is not the fabled Stone Church Cave, but it is context for the next post that I will publish, which is the now revealed – Stone Church Cave.
