James persuaded me to come down this one as I was meant to be having an off day. We first pushed past what was meant to be a sump, although it was not it still drowned my phone. From here was tight, very bruising tight yorkshire style passage where we were forced to stop at a too tight corner. We returned back through the duck and took a look at a side passage and got to where we meant to be which was an upstream low bit (the passage here was a lot easier). This was meant to be too tight but we easily got through into a large chamber which had us in awe. There were many side passages but we have not pushed them due to no survey gear. We need to come back.
