The Group's aim is to identify, survey, protect and promote geological and geomorphological sites in the former County of Avon - the modern unitary authorities of Bath and North East Somerset, Bristol, North Somerset and South Gloucestershire. RIGS are selected for their educational, research, historical and aesthetic value.

RIGS of the Month

The Avon area includes well known sites such as Aust Cliff and the Avon Gorge, as well as lots of other less famous but equally fascinating outcrops. Our monthly feature 'RIGS of the Month' aims to explore all that Avon geology has to offer and provides a starting point for anyone wishing to visit the RIGS themselves.
