We start with an indoor talk followed by a drive and 3 short walks, as far north as Upper Badcaul. Car sharing can be arranged. Andy Moffat will consider some igneous intrusions within the Lewisian Gneiss and the unusual minerals they contain. The walk will provide the opportunity to see many aspects of the Lewisian rocks. £5 on the day.
