So we got a good auld survey trip done yesterday, even if it did mean missing the rugby! After much faffing and waiting for faffers (blame seems to have mostly been attributed to Ms Lindsay), we all travelled down from Belfast, grabbing a Wetherspoons breakfast on the way through Enniskillen. Our aim was to climb the waterfalls from Tullyard main chamber and survey the upstream portion of the cave, and with this in mind (and the expectation to get to the pub for the rugby) we left a callout of 8pm with Les (sorry Les!) expecting to be out by 5 or 6. As it turned out, the passages took a good while longer, and we realised that it also holds a couple of interesting things to return to...Steve Bus was the only one of us that had been in upstream Tullyard, around 6 years ago, in fact he could well have been the last caver to even go there. I'd been up the main waterfall once but no further, stumped by the next narrow climb. So Stevo climbed up and rigged an SRT belay on the first section (rigged off the single rusty hanger and the loose boulders hanging over the waterfall :-o) and helped (read: dragged) the rest of us up the next couple of climbs with some slings.Above the short set of waterfalls (around 6m from the base of the large waterfall) the horizontal passage starts, and looks much like a smaller scale version of classic Shannon passage, generally canyon-shaped, with smooth-sided walls and gravelly floor interspersed with sculpted rocks. The first notable feature we came across was a partially hidden shaft off to the right of the main passage, entered under an overhang. This is labelled on the COFAC2 survey as "Fossil Pot" and is a fine vertical shaft about 8 m in height, and which Stevo climbed to discover a horizontal fossil passage above it, roughly crossing the direction of the streamway. In one direction it rises a further few metres before choking (according to the survey data it is rather interestingly close to the Polltullyard surface doline....) while in the other, some work with a hammer would make it wide enough to push into wider passage beyond.Further on upstream is an obvious reverse left-hand branch, which chokes impenetrably within 12 m; judging by the torrent of water pouring through the choke, this is the point where the stream sink next to Polltullyard entrance joins the cave, approximately 10 m directly above the passage. Further on the passage becomes a nice keyhole shape, all still easy walking. Damien has some nice pics from here. After another 40 m or so the last obvious side passage is reached, again as a tight left-hand branch. This goes for a good 40 m of walking/stooping through knee-deep mud, and featuring some pretty stals and helictites, before the ceiling lowers and meets a "sporting" mud duck (yay!) which myself and stevo pushed to reach a small 3-man chamber and another low duck before becoming a sump. I suspect that the sump isn't all that long though, so given that the passage up to this point is on an uphill slope, we are tempted to return with some hosepipe to siphon the water (erm, mud) out and see what might be beyond. The passage goes in quite a strange direction and we're intrigued as to where it might lead.Back in the main stream passage, there is an unexplored climb above the junction (around 6 m climb) with what appears to be vadose fossil passage at the top of the narrowing canyon rift. Beyond the junction at stream level the canyon becomes tighter, with some crawling leading to a large chamber featuring a dodgy boulder slope on the left. An upper level of the previous canyon can be accesed from this chamber, with some nice formations. Down and to the left, easy stooping streamway continues, passing by a fine moonmilk slope. After a small boulder chamber which appears to be the end of the current COFAC survey, the streamway becomes low and awkward for the last 20 m until the ceiling lowers and the passage becomes too tight to continue. Roisín and Stevo spotted a large number of shrimp in the stream here so we recommend steering clear of this section if possible. We started the survey from the end point and worked our way out, finally making it back to walking passageway much later than we expected -- and with the surveying of the rest of the meanders and canyons and our little mud bath, we didn't make it back to the surface til, erm, quite late. Les had kindly waited around for our emergence after watching an enormous shower come down at 7, and so he met us at McGourty's yard at around 8.20 desperately trying to find signal on our phones!Still, the survey of this section is now complete, and a rope has been temporarily left in place for getting up the first pitch (please avoid using the old sling, God only knows how old it is), but there is talk to return within the next month or so and place a couple of handy bolts to allow a single pitch and an easy traverse to avoid the dodgy climbs. We tied the survey to the spit on the wall at the bottom of the main chamber, and I've now compiled the data.Facts and figures:
