Opening a tube in the Eramosa Karst
Some people might wonder what is wrong with this guy, why he might spend his Saturday afternoon in this disgusting manner, but in truth, he could think of no better way. (There is some air space just above the water behind me)
This picture was taken just before the duck that leads into the cavity as shown in the previous post.
You can see the scalloping on the walls. They give clues to the type of water flow. There are especially large scallopings in the space beyond. This is indicative of a relatively slow moving current. In caves where there is constriction at a ventury or narrow opening you will see small scallops indicating an especially turbulent flow. (eg. just above the water filled tube in Museum cave)
At this time I had not seen anything beyond what you see here but the cave had been breathing in and out and I was quite optimistic of onward leading passage.
There are a couple of interesting digs that have taken place in the area, one of which I am presently involved in and one that I had been participating in a couple of winters ago – the details of which were published in the Toronto Caver (Club magazine of the Toronto Cave Group).
In this winter dig that I had participated in – (XS Wire Cave), we had worked our way along a crevice for several feet down to a rocky tube. Our progress had been temporarily halted by a lump in the bottom of the passage. In freezing water (30 below up top) Greg Warchol removed the lump and we continued on to an “almost sump”. I suppose we could have continued on – there was an echo from above the pool where we stopped, but the logistics and effort were just to much. Hindsight says I wish we had.
In light of the comment made in the preceeding post by Andrew, I am encouraged to hear that others are also having some success. Be safe please – caving can be hazardous.
