A combined project between the Toronto Cave Group and Ontario Cave Divers

Not bad for Ontario eh?

Beleive it or not this is a cave dig. The TCG and Ontario cave divers all worked on this project for a number of years. As you can see, it proogresed on through the winter. Generally speaking, at its lowest level the water was about knee deep when the pumps were running. As soon as the power stopped the pit began to quickly fill with icy water.

That tube that looks like a fire hose hanging into the pit was connected to a suction nozzle that sucked up gravel, clay and dirty water which were dumped out in the adjacent field.

Many believe that this is a tunnel that had formed before the ice age in an area known as “The roof of Ontario”. It would appear that the exposed rock in the area had once been an active karst but as it was buried under clay it stopped developing. We found numerous large bones in this pit (ice age caribou amongst them), but inexplicably the project ground to a halt shortly after we reached the source of the water – an underwater tunnel.

Ontario cave with a scary past.

The picture is a little blurry but I thought that I would post it today in memory of a time not so long ago when I was able to go outside without my nose almost freezing solid.

This is Donald of the SQS – a Quebec caving organization. Donald, Corneilie, Marc Andre and I had entered this Ontario cave and we followed it to its sump where there had been an especially harrowing diving accident some years ago. Two divers followed the underwater tunnels inward and only one returned. Fortunately the diver who came back went back to the surface for extra air tanks and then returned to rescue his buddy who had found an airpocket somewhere.

What was especially cool about this cave – aside from the dip at the entrance was the bats. They were fluttering around in the tunnels in significant numbers – possibly leaving the passages by an entrance other than the one we had used.

In reaching the furthest extent of the passages I was very interested to see the sandbars which seem re-worked each year. I cant be sure – maybe I was just confused by the map but in retrospect I think that maybe a passage; that is not mapped has been exposed from behind a sand bar. I hope to visit when the weather warms up to be certain. I was reluctant to probe further on my last visit as I did not want to disturb the sediment but with a map in hand I can seperate my confusion from reality. It’s probably just wishfull thinking though.

Eleven kilometers of tunnel have been mapped beneath a large Ontario river. In places the passages stretch out across the bedding planes to nearly 90 feet in width. Some passages are still and cold, others have massive currents that threaten to sweep the unprepared off into blackness – one cave diver already lost his life there. The photo above shows an inland pool where one such tunnel breaks open close to the surface. Locals say that these places are great for fishing.
