1970 Mount Everest disaster

The 1970 Mt. Everest disaster is the term for the avalanche death of six Nepalese Sherpa porters on 5 April 1970, who were killed on the Khumbu Icefall of Mount Everest while assisting the Japanese Everest Skiing Expedition 1970 climbing expedition. Four days later Sherpa Kyak Tsering, a porter on a different Japanese Mt. Everest expedition, was killed by ice falling from a serac. Later, Yūichirō Miura, the focus of the film expedition, became the first person to attempt to successfully ski down Everest.

The icefall, which lies between Base Camp and Camp I, has been the site of numerous fatalities, including those in the 2014 Mount Everest ice avalanche. The six 1970 victims were Mima Norbu, Nima Dorje, Tshering Tarkey, Pasang, Kunga Norbu, and Kami Tshering.
