I 'explored' some new passage beyond Sump 5 in Otter Hole on Thursday, that slowly closed down to a dead end with no air flow after about 12m. If if had gone, it would have doubtless had a jubilee themed name, but as it is, I don't think it quite warrants naming.
Spotted a more promising lead beyond Sump 6, but didn't have time to dig the plug of mud out the entrance and see if it's a goer. Fresh air in that one at least and can see about 10m in caver sized passage... Perhaps if that one goes, it can get a back-dated jubilee name...
