Since the avalanche, expedition teams have declared a week of mourning. About 400 foreign climbers from 39 expedition teams were on the mountain with an equal number of Sherpa guides, along with many more support staff such as cooks, cleaners and porters in the base camp.
At least one expedition company has canceled this season's attempt for its six-member team.
"Our team members have empathy for the Sherpa community and we wish for everyone to be able to mourn their lost family and friends in peace," the Adventure Consultants Everest Expedition 2014 Team said on its website.
More than 4,000 climbers have reached the top of the world's highest mountain since 1953, when it was first conquered by New Zealander Edmund Hillary and Sherpa Tenzing Norgay. Hundreds of people have died trying.
