At the top end of a precipitous limestone valley near Toronto JC and I had found this pipe that ran up into a concrete barrier. That day we had been looking for caves on a tip from andrew. I believe we may have found what he had described (more on that in another post), but more to the point of this picture, we found this curious rusty pipe. well it was hard to ignore the mole in me and I soon found myself crawling up it – wondering where it went.

See video here that shows a little of that day and the crawl up the pipe and what I found at the end.

I suppose there is still room for urban exploration out in the countryside, and sweeter yet is something that is old and decaying in a forgotten valley.

Stay tuned as this coming weekend JC and I are again heading northwards for some serious Ontario cave exploration. We have several leads, in particular pushing Milo Cave and hopefully opening the extension of the tunnel that leads on beneath a granite hillside. Of course the semi – albino crayfish are encouraging.

As you might guess by my post I did not go to P-Lake today. I woke up At around 03:30 with a terrible headache (I always get one when the clouds are moving in and I hear we are in for a severe rainstorm tonight) and I thought  – “I’m on holiday, why do I want to do this to myself.” It’s a 5 hour drive either way, lots of hacking through the bush and then I’m not even sure of where the cave is. Last time almost killed me. So instead I switched the alarm off and slept in till about 10 and then I went south for 2 hours instead of north for 5 – to the Queenstone Sandstone Mine. It was relatively easy to find and just as big and mazy as I remembered from that trip with Dan about 10 years ago. Only thing that has changes was the path to get there.

See that pillar in the middle of the room – go ahead kick it – I dare you.

There’s a crevice that cuts under a cliff face. It leads to an underground lake that just goes on and on. Dan and I spent about two hours underground wandering waist deep in water. I am thinking that the mine is somewhere between 100 and 170 years old.

Back in the 1820′s and 30′s there was a serious demand for building stone in Southern Ontario; Whirlpool Sandstone was one of the most valued materials. It was extracted from a  layer just above the Queenstone shale.

Near Belfountain you can see this rock at the base of Church’s Falls. See the chapter on Belfountain on page 69 of my book “Rockwatching; Adventures Above and Below Ontario” The rock that came from there was a maroon color and was used to build Queen’s Park and various buildings at University of Toronto. Down here in the more southerly areas of the escarpment the Whirlpool Sandstone seems a lot higher on the escarpment than it is further to the north. It is also more varied in color and I am told that it is possible to find azurite and malachite in chert pockets in that rock.

Anyway the construction of the Welland Canal generated a great deal of demand for building stone as did the increasing size of the urban structures around the “Golden Horseshoe.” Finally around 1900 the skyscraper came into being. The strength of the modern skyscraper comes not from its rigid outer shell but from its internal steel girder skeleton. This change in design meant that standard construction stones suddenly lost their market and materials such as Italian and Indian marbles started showing up. They formed a thin veneer as did materials like glass, labradorite and granite. they were in no way responsible for the buildings structural integrity. Sandstone had seen its day and the mines closed shortly thereafter.

Some years back year Jeff Mirza and I traveled up to Belfountain to see if we could find our way into one of these underground tunnel systems. Apparently there are several deep passages above the hairpin bend as you wind down from Belfountain into the Credit Valley. Jeff had even seen a picture of a shaft in the forest with a ladder leading down into the mines. After a day of trudging along the hillsides we came to the conclusion that the entrances had all been blasted shut. It was not the case here. The tunnels lie wide open. It was as much a historical exploration as it was a geological one. The rooms were quite low though generally very wide and initially lit by small shafts that cut up to a brambly plateau above. The vegetation was so thick that it was almost impossible to progress on the surface, nevertheless, the shafts of light on the underground lake were really picturesque.

At times high banks of rubble rose out of the water and it was necessary to slither along on our bellies. In places deeper into the mine calcite deposition had made a hard, translucent shell across the top of these banks and we had to be careful so as not to damage the profuse clusters of soda straws that were forming on the roof. The bats seemed quite perturbed by our arrival in their world and somebody was cheeping angrily from up a crack in the roof. On several occasions they fluttered by and I could just catch glimpses of their chaotic flight. I was surprised by the extent of speleothem formation in the mine. I had believed that under good conditions soda straws could grow at about an inch every hundred years though in remembrance of a winter excursion Jeff and I had done up a storm sewer in Hamilton a few years back, that one inch can be quite drastically stretched.

As we waded through the lake there were tunnels that branched off in every direction, the air  seemed dead and the steam that rose from our coveralls clung to us. it made photography quite difficult.

The water was so still and clear in one spot that I was surprised by the ripples when I crawled right into a pool. We continued on along a mound that was just beneath the surface. Dan wandered off to the side into the deeper water and suddenly found himself hip high in really treacherous mud. I had a similar experience moments later and we decided that further exploration would have to be done with an air matress. Up ahead it sounded like a heavy rainstorm and I think that there must have been a spot where the water was pouring in.
