The Terrifying Last Minutes of “Dr. Death” – Derek Hersey
May 28th, 1993. Yosemite Valley, California. Derek Hersey had spent sixteen hours climbing the sheer face of El Capitan on a single can of Pepsi. This is the story of his final hours.
1. The Man Who Became “Dr. Death”
Derek Geoffrey Hersey was a British rock climber who specialized in free soloing – climbing without ropes, harnesses, or any protective gear . Born on October 26, 1956, in Stretford, Greater Manchester, he learned to climb on the gritstone crags of the Peak District before moving to the United States in 1983 .
In Colorado, he became a fixture of the Boulder climbing scene, treating Eldorado Canyon as his “office.” His ability to solo routes in the 5.10–5.11 range, combined with his willingness to push the limits of the sport, earned him the nickname “Dr. Death” .
2. The Day Before: A 16-Hour Marathon on El Capitan
On May 26, 1993, two days before his death, Hersey and his friend Craig Luebben climbed The Nose – the legendary 3,000-foot route on El Capitan . They started at 5:15 a.m. and topped out at 9:00 p.m., spending 16 hours on the wall .
The climb took a toll. Hersey’s legs cramped during the descent because he had consumed only a single can of Pepsi and no food during the entire marathon climb . Luebben later speculated that Hersey’s legs were still fatigued when he set out for his final climb two days later .
3. The Final Climb: A “Moderate” Route That Became a Trap
On May 28, 1993, around 11:00 a.m., Hersey told Luebben he was going to free solo the Steck-Salathé Route on Sentinel Rock – a 5.9-rated route that was considered “an easy day” for a climber of his skill level .
The 7,000-foot peak of Sentinel Rock is located across the valley from El Capitan. By all accounts, Hersey was in high spirits and not suffering from depression or any personal problems .
Luebben estimated it would take Hersey three to four hours to complete the route and return to their campsite by around 6:00 p.m. .
4. The Terrifying Last Minutes: What Went Wrong?
At approximately 1:00–2:00 p.m., rain showers swept through Yosemite Valley. Witnesses reported rainfall hard enough that climbing parties on other routes rappelled off because the rock became wet and slick .
Hersey was likely already well into the climb when the rain began. The rain-slicked rock appears to have been the fatal factor . Slippery conditions on the smooth, polished granite of Sentinel Rock proved treacherous even for one of the world’s best free soloists .
He fell several hundred feet to his death . His body was discovered the following morning on the second-class ledges at the start of the Chouinard/Herbert route, at the bottom of the fall line of the Steck-Salathé route .
5. The Search and The Aftermath
When Hersey didn’t return by darkness on May 28, Luebben grew concerned but initially waited, knowing Hersey might have gone on to climb another route .
At 5:30 a.m. on May 29, Luebben checked Hersey’s tent. Finding it empty, he reported Hersey overdue. Rangers found his body at 11:30 a.m. that day .
