+Went back into Under a Rock and dropped the pitch. The bottom was a tall rift, up didn't go far, the way the water flows rapidly got too narrow. We followed the 3rd way on, up a short climb and down the other side (via a bolt). We scrambled further down and down some more to find ourselves back at the bottom of the p32. Olly was amused at where we were, I was annoyed. But at least our loop closure was good! +
+Went back to entrance chamber to survey out. Olly spotted a hole thru' some rocks. It drafted so we pulled some rocks out. We couldn't easily make the gap big enough, so tried a meter or so higher up. I managed to get through, and amazingly got under and through a window into another passage underneath Down Under, removed more rocks so Olly could follow me through. Followed the passage past a squeeze and a climb down. Found ourselves above a reasonable sized passage ~5m above. Didn't look climbable down, but I could traverse over. Did this to another 6m drop into the same passage, but excitingly could see a snow plug. We wondered if this was 107. Surveyed out and up to the tag bolt. +
+Scrambled in 107 on the way back and saw a similar looking snow plug. Down the hill the survey data confirms we connected! Not as impressive as The Connection, but we have made 107 ~9m deeper (by the CUCC way) and ~500m longer. +
++Went back to 83 for the actual final trip. I retrieved the rigging gear while Olly sketched the entrance chamber. I derigged and swung across to look at side tubes. One near the top generated another ~15m of passage. +
+Finished de-rigging. [rigging diagram in original] +
++Went to 148 and rigged in the first 4 pitches (i.e. to just before deep space). I'd forgotten how cold and drafty 148 is. +
