Dan Anderson was lying on the forest floor when he regained consciousness. He had no idea how much time had passed. Had it been a couple of hours or a full day? His last memory was of falling about 50 feet from a large tree. “This is a lot farther than I expected,” he remembered thinking as he had accelerated toward the ground. Dan tried to get up but his legs wouldn’t work, and hot searing pain coursed through his pelvis. Feeling an “indentation” in his back, he knew he had broken it.
