Monday 17 September (Indoor Meeting): 'Geological Highlights of South Devon'. Speaker: Alan Clewlow. South Devon is renowned for the sheer diversity of its geology, including igneous, sedimentary and metamorphic formations, and fossils. Alan Clewlow will draw on his 30 years of experience of fieldwork in South Devon to describe a landscape which is not only diverse geologically but also very accessible to visitors, particularly along its coastal paths.
