After crawling for half an hour up Pond Creek you pass beneath a shaft that leads up to a manhole cover. There are several flat shelves around this intersection that are piled high in molding fecal matter. I suspect that this is the central hub for the neighbourhood’s raccoon traffic.
Ten minutes further along will put you at a passage that opens out from a claustrophobic slot into an arched dolostone tube. The floor is of wet, musty smelling gravel and it dips into a pool at the bottom of a natural, stone lip.
Old maps of the area led me to believe that somewhere up ahead the tunnel will fork. In a back garden near exhibition park I am told that there is a well where the property owner drops a bucket down to a pool of water. This surface portal might be just beyond the beam of my headlamp but I have only pushed the passage a little further. The stoop walking and crawling is a killer on the knees and thighs.
Check out the speleothems growing on the roof. The explorer must be careful so as not to damage them as these growths are easily snapped.
This was undoubtably one of the more unusual urban explorations that I have made. A future trip that I am considering is up a tunnel from which echoes this most incredible roar. An upstream wade in neoprene should prove quite interesting as I suspect that it leads to an under-city waterfall.
