Protrusions, corners, edges, slits, and cracks in the smooth rock face provide support to overcome your own gravity. You also need two hands, two feet, careful preparation of each step, gentle probing and testing of possibilities with your fingertips, and, last but not least, the group that stands by your side to advise and protect you. There is a lot of sweat, a little blood, and above all a lot of energy. Climbing, slipping, falling, trying again. In the end, climbing to the summit entirely under your own steam, yet together.
