44,000 meters of climbing, 1100 pitches of rope, and 40 routes: these three figures confirm that Adi Stocker has not written your average guidebook. Extremely well illustrated, the highest limestone walls of the Eastern Alps are presented by climbing authors with a great deal of experience. What is their method for pushing themselves even further? Climbing routes at least twenty pitches long, thus the origin of the title, “Longlines”. The list includes modern bolted routes (like ZehnnachFünf, in Dachstein, 30 pitches, 1100 meters, 70 bolts), as well as older classics protected by pitons, and that one must climb with extreme caution ( North Dihedral on Lalidererspitze, 32 pitches, 850 meters). Adi Stocker does not stop at simply showing these climbs through spectacular photos; he also provides the history of each, a precise sketch of the route, and a complete description. In the end, this book is a worthy tool when looking for ambitious objectives.
