Before going farther, Yeager had to transfer his rack from the rope he had been descending to a new one that would take him to the bottom of the 23-Meter Drop. He made the change successfully, leaned back to begin his rappel, and realized instantly that something was wrong. The rope did not stop his backward-tilting motion. Instead, he kept going, as if tipping over backward in a chair. Somehow his harness had become separated from the rappel rack, which was still attached to the rope. Instinctively, he lunged to grab the rope and the dangling rappel rack. Had he been carrying no pack, or even a light daypack, it’s possible that he might have saved himself by holding on to the rope, or to the anchor bolted to the wall, or perhaps even setting up something called a body rappel. But that would have required almost superhuman strength and would have been extremely difficult even without any load. His fifty-five-pound pack made any such self-arrest impossible, and in another instant he was dropping through space. He fell so quickly that he did not even have time to scream. Falling rocks can shatter and ricochet like shrapnel; Peter Haberland had moved off and sheltered behind a boulder, so he did not see Yeager land. He realized something was wrong only when he heard a rush of air and the crunching impact of a long fall ending on solid rock. Praying that Yeager had dropped his pack, Haberland called out, but he got no answer. Within seconds, Haberland found Yeager, lying beside the bottom of the rope. He was in a pool of water three inches deep, on his right side, his face partly in the water, his arms stretching forward, as if reaching for something. Yeager’s right leg was broken, the foot rotated grotesquely 90 degrees so that while the body was on its side, the foot pointed up. He had no pulse or respiration, but Haberland turned his face slightly anyway, to keep his mouth and nose clear of the water. Haberland rushed down to the Cheve expedition’s Camp 2, a twenty-minute descent, where he found two other cavers, Peter Bosted and Jim Brown. They left a note hanging from red-and-white survey tape and rushed back up to Yeager’s position with a sleeping bag and first aid supplies. When they arrived, they found that some blood had run from his nose, but there were no other changes. All three attempted CPR without success. Chris Yeager was dead. Understanding precisely why the accident happened requires a detailed knowledge of caving equipment. But the root cause was not equipment failure; it was “pilot error.” Yeager entered the cave with too much weight, became fatigued, misused his equipment, and, last and worst, failed to properly secure the locking carabiner that connected his harness to the rappel rack. He apparently made this mistake not just once but twice, the first instance having caused the rack’s earlier loss. LEARNING OF THE ACCIDENT, Bill Stone could only shake his head in dismay. He had been uneasy about Yeager’s presence in camp in the first place. Yeager; his girlfriend, Tina Shirk; and another man traveling with them had not been part of the original expedition. After climbing some volcanoes, the three had traveled to the Cheve base camp. Shirk was a competent caver who had been in Cheve the previous year but, with a broken collarbone, was not caving just then. The other man had told Shirk and Yeager that, earlier, he had secured permission for Chris to go into the cave. There is some disagreement about that, but Stone, for one, knew nothing about it. As far as he was concerned, the trio had “crashed” the expedition. Yeager’s death affected everyone. Peter Haberland later wrote in a caving magazine article that he was “shattered at that moment.” Tina Shirk was devastated. Other reactions ranged from anger at an overzealous rookie to grief over a young man’s death to horror at the reality of a body decomposing down in the cave. For his part, Bill Stone was saddened by the needless loss of a young man’s life. He was angered because Yeager’s death left the leaders and the team with a thorny
