Building up the shots for the photo library of the Dan Yr Ogof cave means that we do get to go to some obscure places, and this trip was to be no exception. The aim was to go to Productus passage, a Phreatic tube high above the Green Canal that contains lots of glutinous mud.

En route to the Green Canal we stopped off to look at the pretties in Flabbergasm Oxbow and also provided action sequences for Keith’s video as we went through the Long Crawl. On reaching the Green Canal I carefully wrapped my SRT tackle bag in a life jacket to ensure that I did not befall the fate of Keith, but I hadn’t got 10m along the canal before I realised that bag had come away from the life jacket and was now at the bottom of the canal! After a couple of minutes treading water in search of the bag we carried on and shared kit to get up to the passage 20m above the Green Canal.

The passage takes its name from a prominent fossil marker bed. The roof of this passage is so thin in places that it collapses and the shale band above drops down to form small chambers. It is in these small chambers that some beautiful arrays of straws and formations are found.
