This is another of GA’s guides, this time to the geology and geomorphology of the popular holiday destination of the Castleton Area in Derbyshire. I love this area and have visited there both for the geology and the beautiful scenery.

This was the first GA guide I ever bought, and I suspect it is still the best. My copy is more than well-thumbed and water-damaged, through many a happy trip to the south of England to collect, what a friend describes as “white fossils in white rock”.
