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.
