Survey: OUCC 1967 » (known to be missing side passages near the entrance)
Description: Large cave (1000m) explored in 1966/67 by OUCC; See OUCC Report 1967 » (called ‘Penilla’ in that report).
Visits:
2000 – brief initial exploration
2001 – explore major inlet series on the right (with Spanish survey mark F7); this is missing from the survey and yet sources all the water in the cave – meaning that the main stream is completely unaccounted for
2003 – GPS
2007 – brief ‘warm-up’ trip
Other:
Worth another visit.
