Hillary Step
The Hillary Step was a 40-foot vertical rock face that sat above sea level on the southeast ridge of Mount Everest. Located halfway between the "South Summit" and the true summit, the Hillary Step was the most technically difficult part of the typical Nepal-side Everest climb and the last real challenge before reaching the top of the mountain. The rock face was destroyed by the April 2015 Nepal earthquake.
Located in the death zone, the Hillary Step was Class 4 on the climbing-difficulty scale. One expedition noted that climbing the Hillary Step was "strenuous" and offered little to no escape from unpredictable, rapidly changing weather.
Heavy snowfall could enable climbers to bypass Hillary, by way of snow and ice climbing.
The Hillary Step has claimed several climbers' lives. In 1997, mountaineer Anatoli Boukreev – known for saving the lives of climbers during the 1996 Mount Everest disaster – found the body of Bruce Herrod hanging from ropes at the base of the step; Herrod had died during a climb two weeks after the 1996 disaster.
Climbing
The step was closed during the 1953 British Mount Everest Expedition by the First Assault Party of Tom Bourdillon and Charles Evans when they reached the South Summit on 26 May at 13:00, too late to continue on. Seated on the snow dome, they could look closely at the last ascent to the summit. It was not the gentle snow ridge they had hoped for, but a thin crest of snow and ice on rock, steep on the left, overhanging as a cornice on the right. It was interrupted by a formidable-looking rock step two-thirds of the way up.The feature was named the Hillary Step after mountaineer Sir Edmund Hillary, who, together with Sherpa Tenzing Norgay, became the first to climb it during their 1953 ascent of Mount Everest. Positioned just below the summit ridge, it marked the final major technical obstacle on the Southeast Ridge route.
In his 1953 account of summiting Everest he wrote:
In more recent years, the ascent and descent over Hillary Step were generally made with the assistance of fixed ropes, usually placed there by the first ascending team of the season. In favourable conditions, it was about two hours from the South Summit to the Step, one to two hours to climb it, and a further 20 minutes from its top to the summit of Everest. Before 2015, the narrowness along this section meant that only one climber could pass at a time, and as the number of ascents grew it often became a bottleneck, with climbers waiting their turn on the fixed ropes and slowing movement both up and down the route.
2015 alteration
It was suspected in 2016 that the April 2015 Nepal earthquake had altered the Hillary Step, but there was so much snow it was not clear whether it had truly changed. Kenton Cool wrote that the Hillary Step "is only 12 to 15 feet high." In May 2017, Tim Mosedale and other climbers reported that "the Hillary Step is no more", although the full extent and interpretation of the changes were still nascent. Another climber who thought the Step changed by 2016 was six-time Everest summiter David Liaño Gonzalez, who summited in 2013 and 2016, when the relevant changes are reported to have occurred. However, some important Nepalese climbers, including Ang Tshering Sherpa, chairman of the Nepal Mountaineering Association, reported that the Step was still intact but covered in more snow than before. Later in the year, after seeing a large exhibition of photos from 2006 to 2016, he did agree that at least the upper portion of the step had indeed changed.Peter Hillary, Edmund Hillary's son, was asked his opinion about the Step based on photos. He agreed it was there in part, but seemed to think it had undergone some sort of a change, noting especially what looked like a fresh broken rock. By early June 2017, more reports and photographic evidence came in, with Garrett Madison reporting that the step had conclusively changed. Dave Hahn, who has climbed Everest 15 times, was shown photos and agreed that it was changed. A special kind of mourning hit the community with realization of missing rocks and freshly hewn scars of new coloured rock at this landmark feature. Hahn noted how it was a great tribute to Hillary and Tenzing and he thought of them whenever he scrambled over it.
Later in 2017, mountaineering guide and trained photographer Lhakpa Rangdu mounted a photo exhibition at the Nepal Tourism Board showing how the Hillary Step area had changed. Rangdu has climbed Everest multiple times since 2005, including before and after the big Nepal earthquake. The combination of these skills—high-altitude photography and mountaineering—allowed him to provide a photographic history of the Hillary Step, and he has said that it is indeed gone.
