Four people have been found dead in tents on Mount Everest, bringing the death toll for this climbing season to 10.Nepalese Sherpas discovered the bodies in tents at Camp IV, the camp closest to the summit of the world's tallest mountain. It stands at an altitude of more than 26,000 feet, near the so-called death zone where there is very little oxygen.Mingma Sherpa of the Seven Summits Trek group, the company the Sherpas worked for, confirmed the news to The Associated Press and Reuters on Wednesday.The identities of the deceased climbers have not been released, though The Himalayan Times reportedthat two were Nepalese and two were foreigners. It said one was a woman.While the cause of death is not yet known, the fact that they apparently died inside tents led seasoned Everest blogger Alan Arnette to speculate: "It is most likely they died from carbon monoxide poisoning by using their stoves in the tent without proper ventilation."The Times said the Sherpas found the climbers while trying to recover the body of "49-year-old Slovakian solo climber Vladimir Strba who died at Camp IV on Sunday afternoon."Everest is particularly busy at the moment because the Nepalese government has issued a record 371 permits for foreign climbers, the AP notes.Deaths on Everest are tragically common — at least 200 people have been killed attempting to climb it since 1920, the BBC reported. "However, the numbers of people attempting the climb have also skyrocketed since 1990, when the Nepalese government withdrew restrictions on how many teams were allowed on to the mountain — which means the percentage of climbers who die has actually dropped."British Everest expedition leader Tim Mosedale wrote in a recent Facebook post that the increasing number of climbers has led to more guides who are less-experienced:
