Evening trip in to resurvey St Valentines, following a UKCaving post a while back to see how close it was to Corkscrew Aven. Once done we went up Geology Aven, to rig a rope up the last pitch, and to checkout the dig face and associated draughts. An entertaining smoke bomb in an enclosed space encouraged a quick retreat, although epic fail as we still missed the pub.
