Pumori

Nearly 500 people had summitted Pumori by 2005, at a cost of 42 lives.[6] It was noted for its increasing popularity by 2008, with such features as being able to use the Everest base camp for Nepal (when occupied) when trekking or climbing Pumori and offering views of Tibet, Nepal and Everest.[6] However, there have been some dangers from avalanches including some Spanish climbing teams that took heavy losses (such as in 1989 and 2001),[6] and the 2015 avalanche, which was triggered by the 2015 earthquake, originated from the Pumori-Lingtren ridge.[7]

In 1982 a group climbing to Pumori also did a ski-hike around Everest.[8] Jim Bridwell led the climbing expedition to Pumori.[8]

• On 19 October 2002, five Basque mountaineers were swept 600–800 metres down the southeast face by an avalanche caused by seracs falling above them.[13]
• On 25 April 2015 a 7.8 M_W earthquake struck Nepal and triggered several avalanches on and around Mount Everest, including one that hit Everest Base Camp. A witness described it as "a huge avalanche coming off Pumori".[16] The avalanche traveled through part of the Khumbu Icefall and into the South Base Camp.[17] At least 19 were killed.[18]
