Being a cave formed in gypsum, Devil’s cave is relatively well decorated for Ontario. Flowstone has formed in abundance and it appears to have literally blocked the route onwards.
If it were not for the cliff face having collapsed out into the river it would not be possible to enter the small cavern in which I took this picture. In the not too distant past (before the cliff collapsed) nothing any larger than a rabbit could have entered because the tunnels from the outside to the interior were too small.
The lower entrance as detailed in the rumor must have been buried in the slide, though in seeing the upper cavity, one can only wonder as to what lies beneath.
