This amazing picture was taken by Nirmal Purja's Project Possible on 22 May 2019 near the summit of Mount Everest.
Hundreds of climbers line up to reach the summit.
Nirmal Purja, a former Gurkha and Royal Marine, posted the picture of the route to the 8848m (29,029ft) summit on Twitter on Thursday as he warned that the mountain can kill.Mr Purja, who is making a world-record attempt to climb all 14 peaks of the Himalayas in seven months, estimated that there were 320 climbers in the queue.
Despite the clear blue sky, it was minus 25C as climbers, some described by experts as dangerously unprepared, waited for hours in the "death zone".
Deaths linked to overcrowding
The deaths of two adventurers the day before were linked to overcrowding. Donald Lynn Cash, 55, an American, collapsed on Wednesday while taking photographs at the summit. Anjali Kulkarni, an Indian climber who was also 55, died during the descent.
