“Wilde Alb: Naturschätze zwischen Felsen, Höhlen und Wasserfällen” is a illustrated book of the Society of German Animal Photographers. The Swabian Alb and its special geology are presented in grandiose pictures and with detailed describtions. I met one of the photografers, Bernd Nill, during one of my trips. He loves the Swabian Alb and this love can be found in this book. It is actually an illustrated book, but for me it was a travel guide for the discoveries in the Swabian Alb in 2020.
(As far as I know the book is not available in English.)
