22nd February 2018: with Jake, Jonathon, Brockers, Dunc and Mike M.
Mike M and myself dropped further down the route to Sump 23.75 to have a quick look at another potential lead, where a feint air current could be felt. This will be left on the back-burner for the while. We returned, up the climbs, to re-join the rest of the team clearing the alcove. Beyond the alcove is a narrow 'draughting' rift, it is this we are trying to regain access to.
