Unveiling the Secrets of Anglesey’s Ancient Rocks will be the subject of a talk to Wharfedale Naturalists Society on Tuesday. Paul Kabrna will give the talk at Christchurch, The Grove, Ilkley, starting at 7.30pm.

He has spent a lifetime studying geology and Anglesey has held particular fascination for him, given its complex geology, including Pre-Cambrian formations. Visitors are welcome for a £2.50 entry fee, and full annual membership costs £12.50.
