This is a new edition of the classic little guide on Blue John by Trevor Ford, who has now sadly passed away. It is published by the East Midlands Geology Society and has been revised, updated and expanded by Trevor’s colleagues, Tony Waltham and Noel Worley.

This is one of the oldest of the GA’s guides and is currently in its third edition (the first having been published in 1957 and the second in 1972). Although there have been changes in classification and so on, the general exposures are largely as good as they used to be – or they were the last time I went!

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.
