Confident of my hold, I push through the left leg, simultaneously pulling up with my left hand. Suddenly, there's a loud crack. And in that split second, I feel my balance go as the world beneath gives way. Another crack (my pelvis fracturing, I later learn), then a crying out, no words -- just a groan, forced out as I tense on impact, my diaphragm pushed upwards, hard. Pain comes instantly, a sharp burning pain, shooting up from my lower body. I've got no idea what's happened at first -- the actual fall, even now, gone from my memory, removed perhaps to protect me. I can't move! Something's on top of me! -- crushing me against the rocks below. What's happening! What the fuck's going on!? I reach down frantically and feel cold, rough stone. Then, comprehension as to what's happened hits me like a steam train and I push frantically with all my might. Nothing moves -- the pain unbearable in my legs and pelvis, searing and grinding, like nothing I have felt before -- as I begin to struggle violently from side to side, trying to wriggle free.
