Back to Vallinia. First we went down the hole I found with John, it turned out to just go into that chamber I clambered into from the other route, though we surveyed it nonetheless.
We then went and looked at some question marks on the passage on the left before you get to Swirl chamber. This passage actually connects to Swirl chamber again part way along (not shown). The first 2 leads went nowhere, the rest we could not get to as it required some very sketchy leap of faith over some very deep holes. Needs rope and SRT to go beyond and drop down.
We then scurried around a few other bits off of swirl before going back down the walking passage finding we need SRT to continue here, while I climbed down into lower passages which had already been done unfortunately.
