1970 Mount Everest disaster Wikipedia
The 1970 Mount Everest disaster was the deaths of six Nepalese Sherpas in an ice-fall avalanche on Mount Everest on 5 April 1970 in the Khumbu Icefall. The icefall lies between the usual sites of Base Camp and Camp I and is the same icefall that was the site of the later 2014 Mount Everest ice avalanche. The Sherpas were killed by an ice avalanche, and were assisting the Japanese Skiing Expedition (Yuichiro Miura ski Everest expedition). Their names were Mima Norbu, Nima Dorje, Tshering Tarkey, Pasang, Kunga Norbu, and Kami Tshering.
Another death that season was with another Japanese expedition; Kyak Tsering was also killed by falling ice (from a serac).
