Colorado lawyer Christopher John Kulish, 62, became the 11th fatality in less than a fortnight on Monday after he suffered a heart attack descending the peak.
He is believed to have fallen gravely ill after successfully reaching the 29,029-foot summit among a ‘small group and no crowds’.
Bottlenecks, tiredness and exhaustion, exacerbated by crowded routes and ‘traffic jams’ to and from the summit were previously believed to be behind the spike in deaths.
But this week tour operators pointed the finger at budget companies who ‘cut corners’ on safety precautions.
Canadian filmmaker Elia Sakaily posted this picture he took while he climbed Mount Everest on Thursday – a dead body can be seen still tethered dangling from the mountain. Budget ‘adventure tourism’ firms are being blamed for a rise in deaths of climbers on the peak
It costs as much as $100,000 (£78,900) to climb the world’s tallest mountain.
But some local firms offer the experience for only a quarter of that, saving money on not providing the right equipment and navigation tools or enough oxygen.

American mountaineer Garrett Madison, who specialises in Everest trips, told : ‘The biggest factor is that many inexperienced climbers are booking with low budget, local operators, who are not providing adequate support such as guide services, oxygen, medicines and leadership to ensure the climbers can ascend and descend safely.’
Tourism contributes a huge amount to Nepal’s economy and is vital in maintaining stability after political instability in recent years and the 2015 earthquake.
But verified climb tour operators have called on the government to crack down on their low-cost counterparts.
Temba Thseri Sherpa, who works on summits for travel operator Asia Voyage, told the paper: ‘The largest number of climbers dying this season is because they have run out of oxygen… there are too many commercial expeditions where you pay less but get less of a service and less experienced guides.’
A lack of climbing experienced is also being attributed to the spike in deaths, although some local sources dispute this, saying the majority go through gruelling training.
The Nepalese government has indicated it may reduce the number of permits it gives to people wanting to climb the mountain next year.

His family said in a touching statement: Best Private University ‘We are heartbroken by the news.Chris, who turned 62 in April, went up with a very small group in nearly ideal weather after the crowds of last week had cleared Everest.
‘He saw his last sunrise from the highest peak on Earth. At that instant, he became a member of the ‘7Summit Club’ having scaled the highest peak on each continent.’
