Ogof Ffynnon Ddu material

Introduction

This material comes from a trip down Ogof Fyynon Ddu in August 1949, some three years after it was discovered in 1946 by Peter Harvey and Ian Nixon. Little is known about the trip, but in view of many of the Cave Research Group committee being present at Aubrey Glennie's 60th birthday celebrations, including Lewis and Marjorie Railton, Mary Hazelton and Peter Binns himself, it was likely to have been a CRG Field Meet.
