Milo Cave, originally uploaded by Mic2006.

JC and I recently visited this fascinating cave that formed as a result of calcite being dissolved from a fissure. There were little in the way of crystals – nothing like the Aladin’s paradise that is Julia Cave, but still it had a beauty of its own.

See video on Milo Cave here.

The most intriguing part of Milo Cave is the bedding plane crawl that leads from its lower resurgence. The crawl is water washed gravel and you are drawn inwards by a cold breeze that blows from somewhere in the blackness. The roof soon came down so low that crawling for me became very uncomfortable and I resolved to return with a shovel as the only thing that was stopping me was this gravel bar and beyond that a large sprouting of ghostly white fungus.

As I backed outwards, steering as far as possible from some truly horrifying monster sized Ontario cave spiders, I chanced to see a pale, translucent shelled crayfish skittering off for cover. Troglobyte adaptation (spelling?) does not happen within a few generations and to my memory there is little in the literature of Ontario cave and karst studies that mentions albino creatures (Ongley talks of one case near in Stone House Cave).

The breeze and the presence of albino creatures is indicative of deeper tunnels further in. Looking on the surface I see that the direction of the tunnel is intercepted by one possible sink point, but more hopefully it might be leading on beneath a massive hill of solid granite – that being the case, clearing a crawl-way through the gravel would open some really interesting exploration. I wonder if there is a sink point somewhere in the forest beyond the granite hill.

While out looking for caves today we were unsuccessful, but it was not entirely a bust. We found this place where a vigorous stream bubbled up from the wall of a valley.

We had first seen this spot on an aerial photograph, a mysterious valley from which water seemed to flow. We spent most of the day searching the area in hopes that somewhere there would be accessible cave tunnels. According to the landowner, there are plenty of sinking streams on the plateau above this spot. Doug, (I believe that was his name), pointed out a ridge nearby and called it “the great Divide”, water on the far side flowed toward Lake Ontario and water on the side of this stream flows into Lake Erie – the separate watersheds are governed by the Grand River Conservation Authority and the Hamilton Conservation Authority.

Water in Ontario generally seeps from marshes or oozes from the soil, this natural spring was quite a treat. Somewhere on the plateau above this feature we will eventually find the sink point, in fact we have pinpointed several significant sinks from the map search. The biggest problem is to find landowners on a Sunday. As for the local geology it is promising in that the bedrock is limestone and it is exposed right at the surface just thinly covered by a clayish soil. To it’s detriment the rock is fractured and thinly bedded.

Water in Ontario seldom flows from the earth in the way you see in the accompanying picture, but I do know of one really cool spot near Guelph – the headwater’s of the Eramosa River. It is a place called Blue Springs (in a Scout camp), There is this really incredible pool that’s crystal clear with a carpet of the finest beach sand across it’s bottom. If you look carefully you can see the bottom of the pool churning as the water flows from the aquifer back to the surface. there is shattered karst all along the valley, but at this time the areas tunnels are yet to be revealed.
