Formed in 1973, the Society's aim is to advance public appreciation of geology by observation, discussion, field studies, research, illustrated talks and exhibitions. Memberships embraces all age groups from 16 years upwards, regardless of gender or race, and includes those with widely diversified interests. We have a lively program of meetings held on the second Wednesday of each month. Exhibitions at locations throughout the London Boroughs of Harrow and Hillingdon, and elsewhere, give members an opportunity to display aspects of their particular interests and their collections. We also have a good field trip programme to suit all tastes.
