High gill lower cave, Moon rising

Went into the lower entrance and explored a couple of inlets. John got the idea that we should run an out on rock trip and he can lead climb the 8m pitch in climbing shoes and wetsuit. We then walked to the upper entrance and found it collapsed behind a shale bank. Middle entrance is not where NC says it is, as the survey indicates it's in a stream. I then solod the moon rising cave, but had limited time so did not pass beyond point of exploration, at tight corner.
