Staring across the bergschrund, a lump forms in my throat and my stomach churns. Before me lies a deep, dark blue void—a seemingly bottomless icy crevasse at the top of the glacier. The sight is both awe-inspiring and terrifying. Cold air surrounds me, and the sound of water dripping somewhere in the blackness below adds to the tension. When I peer into the darkness, a sense of dread overtakes me. The summit isn’t far from this point. We’re so close, but somehow, it doesn’t feel certain that I’ll ever reach it.
