What is adventure travel in Ontario is for cavers a regular Sunday afternoon. Rob, Jeff, Jeff and I revisited this marble cave to hopefully explore other, thus far un-visited passages.
At this time we have discovered several other likely cave leads in the area, in particular, a sinking stream (thanks Steve M.) with massive potential for tunnels, but unfortunately it will take some land-owner permission and then a concerted effort by a team with capabilities of heavy rock removal.
Within our already visited cave we explored out into the darker nooks that I had missed last visit. We found several going passages. This particular spot as seen above – with the wad of flowstone marks the entrance to a tube that we are yet to explore. Getting to this spot is somewhat disarming as you wade through about 18 inches of water and 2-3 feet of soupy mud. Every step causes the water around you to literally boil with escaping methane. You can feel sticks and branches down beneath the mud and in their decomposition they are releasing gas. I am wondering what effect open flame might have on the journey across the expanse that leads to this spot.
Anyway – distant as this location is from my home in Guelph, it seems to be rife with caving possibilities so the focus for our caving exploits seems to be increasingly concentrated in this area. There are many karst features in the limestone right at the edge of the shield – in part due to the rocks natural suitability and in part due to the acid water running off the shield.
