On April 18, 2014, 16 Sherpas, the great guides of the Nepali mountain range, were killed in an avalanche from the Khumbu icefall, making Friday, April 18, the deadliest day in Everest history. The tragedy brought light to a controversy of Everest summiting that had been brewing for the past few years. Suddenly, there was a spotlight on the high-adventure tourist industry running out of Everest: the overcrowded and littered Everest summit, the fights between Sherpas and trekkers, and the fact that Sherpas do the hardest, most dangerous work of summiting without awards or recognition.
