In this colourful book, Peadar McArdle, Director of the Irish Geological Survey, explains how all the rocks we see around us came to be there. Words and photographs help us to explore and understand Ireland's varied landscape. From granite hills we cross a limestone plain to the western coast and some very ancient rocks. From the black columnar basalt in the north, Peadar brings us south to red sandstones, formed when Munster was at the edge of a desert. There is a wealth of information here for everyone with an interest in rocks and the Irish landscape.
