Sligo is known throughout the world for its spectacular scenery, of which Benbulben is the most famous icon. However, few people are aware that Sligo’s extraordinary landscape is the product of colliding continents and balmy tropical seas, spewing volcanic explosions and crushing sheets of ice. The silent stones of Sligo contain an ancient dynamic story. This book explores some of Sligo’s important rock, fossil and landscape sites. The full details, prepared by the Geological Survey of Ireland, will be used to help conserve the sites for future generations. The initial audit was undertaken by Dr. Matthew Parkes and Claire McAteer and is dedicated to the late Conor McDermot, geologist.
