The trip was arranged by Andy Grimes with the aim of exploring the system as far as the Hall of the Mountain King. Keith was interested in exploring the lower series which is entered via a passage on the left just before the fourth boulder choke. Brendan was interested in photographing large chambers using loads of flash bulbs and requiring the use of a tripod.
So what could have been a simple trip involving the minimum of equipment turned into an endurance test involving carrying several bags of equipment through the system.
The party split into two just before the fourth choke with half the team exploring the lower series and the other half going through the choke to photograph the formations.
