Benbulben is known as County Sligo’s ‘Table Mountain’ and is part of the Dartry Mountains. Benbulben was formed as a result of the different responses to erosion of the limestone and shale of which the mountain is formed. A hard and resistant limestone forms the upper cliffs and precipices. Benbulben was formed during the Ice age, when large parts of the Earth were under glaciers. It was originally merely a large ridge, however the moving glaciers cut into the earth, leaving a distinct formation, now called Benbulben.
