Posts Tagged ‘Grand River’

As JC was in the process of studying for a test today, we could only make a short trip. Our excavation of the Tooth Tube will have to wait till next Saturday. We initially visited a place near Paris called Sinkhole Swamp and that was a bust though the place was quite beautiful. I suppose we should have known it from the start, the whole area is too thickly overlain by till.  On the way back to Guelph we made a diversion to the Galt Shelter Caves as I had never seen them.

I believe I had first learned of the Galt Shelter Caves from Ongley’s Manuscript. He described them as “small”, I add to that description, “shallow nooks in the cliff along the shores of the Grand River – humble in appearance, and by the added blight of spraypaint, not worth the struggle down the cliff face and through the vicious thorn bushes”.

Some of the features were in the upper portion of a heavily fractured cliff face. We climbed a short way to access most and where for the most part pretty disappointed. There was nothing but gutted hollows – cave vandalism at its worst. Fortunately I don’t believe there were any formations to break, just the usual empty cavities of a shelter that had been worn by running water.

Two things that work against preservation of these features, firstly they are well known by local kids, and secondly, they are easily accessible as they are literally within an urban area. Can you imagine the impact of people who did this kind of thing visiting LS Cave or Rovers or the Tooth Tube or P Lake Here.

I am very selective about whom I share locations and this is why..

An unseasonably warm day – early March found JC and I visiting Southern Ontario on a search for abandoned gypsum mines.

Where both the Grand River and the Nith River meet there is the quaint though somewhat aged town of Paris. It has the appearance of having been passed by progress, there are brick and barn board sided buildings in the downtown – somewhat neglected, but full of character. Large mills had once tapped the water power and the mining of plaster of Paris leaves a fascinating terrain of forgotten rail embankments, inexplicable hollows and gullies along the river bank, weirs and beaches where barges once loaded up the chalky material from underground and of course decayed and vine choked foundations.

I was inspired to photograph this backstreet business, ‘The Grand River Experience’ it appears that they offer canoe and kayak rental as well as tours down the river; I believe it was on their website that I had my first glimpse of a riverside gypsum mine – supposedly one of many that are around there. As you might have guessed, there is a connection between ‘plaster of Paris’ and the coincidence of this calcium sulfate material being mined from a conglomerate that underlies the area. It is said that the gypsum comes from Silurian age lenticular deposits on the south east flank of the Algonquin Arch.

Devil’s Cave is one example of a local feature where running water has dissolved away the gypsum and having washed the conglomerate out, there are small cavities lived in by a colony of beavers and decorated by spectacular white speleothems and flowstone.

Having now visited this area several times and followed apparently sure leads, both JC and I are somewhat disillusioned as to the prospects of finding open gypsum adits – though a cave is far preferred. Everything seems blocked up real well (with the exception of a single adit along the river bank downriver from the town). Crossed shovel and pick symbols on a map (available on the internet) generally leads you to a spot where you’ll find an undercut that is pretty much buried in countless tons of soil.

Having long been fascinated by industrial archeology, urban exploration and various forgotten tunnel explorations I’d like to know of where there are old gypsum mines around Paris where an interested person can visit and actually go underground?
