FALL ON SNOW, CLIMBING ALONE and HAPE, HACE

Alaska, Mount McKinley, West Buttress

Chihiro Sakamaki flew to the Kahiltna base camp on June 10 and immediately began climbing the West Buttress reaching the 14,200 foot camp within 10 days. By June 19, Sakamaki had established his camp at 17,200 feet. He began his summit attempt on the next day. Sakamaki reached approximately 19,000 feet and began descending for unknown reasons. During his descent Sakamaki fell around the 18,500 foot level in an area known as The Autobahn. He went a distance of 1000 feet, losing a total of 300 vertical feet. He was experiencing pain throughout his thoracic region, but was able to continue his descent.

On arrival at his 17,200 foot camp he contacted guide Vem Tejas and told him of his injuries. At 2120 Tejas contacted the base camp manager Annie Duquette and reported Sakamaki’s situation. At 2133, Duquette contacted the Talkeetna Ranger station and reported to Ranger Kevin Moore. Ranger Daryl Miller, located at the 14,200-foot camp was then given the message, and he contacted the 17,200 foot camp. It was decided that Sakamaki was seriously injured and would need evacuation. Weather conditions at this time were mostly clear at 14,000 feet and above, but cloudy with whiteout conditions below which prevented any flights until the next day.

Meanwhile, the “AAI 2” expedition, led by Mimi Bourquin, arrived at the Kahiltna base camp on June 4. The expedition reached the 14,200 foot camp on June 14 and had established a camp at 17,200 feet by June 18. The group was feeling and moving well. On June 19 the expedition made a summit bid. At 1500, after reaching the 19,000 foot level, client Debbie Sherman complained of a severe headache and began displaying odd behavior. Bourquin immediately descended with Sherman, who was ambulatory, and arrived at the 17,200 foot camp around 1750. Bourquin and Sherman continued descending and arrived at the 14,200 foot Ranger camp at 2100. Sherman was evaluated by medical personnel and held in the medical tent for continued treatment and observation. Sherman’s condition continued to worsen with increasing periods of unconsciousness, ataxia, and confusion. Plans were made to evacuate as soon as weather would permit.

On June 21 at 0935, the Park Service LAMA helicopter departed Talkeetna. At 1021 the LAMA helicopter picked up Ranger Miller at the 14,200 foot camp and departed to pick up Sakamaki. At 1039 the LAMA helicopter returned to the 14,200-foot camp with Ranger Miller and Sakamaki, picked up Sherman, and continued to the 7,000-foot base camp. At 1123, pilot Jay Hudson took aboard Sherman, Sakamaki, and Paramedic Ranger Eric Martin, and flew to Talkeetna where both patients were transferred to Alaska Regional Hospital via Flight for Life helicopter. Sakamaki was treated for broken ribs and released after three days. Sherman was held overnight for observation as her symptoms of high altitude pulmonary and cerebral edema subsided.

Analysis

The “AAI 2” expedition never gained more than 1000 feet per day, which is generally the safe rate of ascent in avoiding altitude illnesses. However, it is not uncommon for individuals to begin suffering from HAPE or HACE during or after a summit attempt regardless of how acclimatized they are. In addition, though small groups are statistically at more risk of obtaining an altitude illness from ascending too rapidly, large groups are also at an increased risk as members may be less likely to report early symptoms of altitude sickness.

The area in which Sakamaki fell has been the sight of numerous falls with injuries ranging from twisted ankles to head injuries. This section is not technically difficult but is steeper than surrounding terrain and often very icy. Sakamaki may have been able to avoid his accident simply by using more caution and slowing down, since climbing solo did not allow any type of practical belay. If Sakamaki had not been able to walk after his fall the consequences would have been far worse as there were few, if any, climbers descending behind him.
