How could this happen? This is usually the first question that arises after a mountain accident. And this is exactly the question that Pit Schubert, who has been the head of the safety circle at the German Alpine Club for 32 years, seeks to answer time and again - always with one goal in mind: to learn from accidents, to recognize their causes, and to make them preventable. Schubert reports on dramatic weather changes and thunderstorms, analyzes the safety of climbing equipment and its practical application, as well as the development of belaying and safety techniques. He shares experiences and episodes related to crevasse danger or the situation with anchors in the mountains. He repeatedly points out mistakes made in sport climbing and mountaineering, and highlights dangerous situations that everyone, whether a hiker, climber, or mountaineer, has likely encountered at some point.
