The Khumbu Icefall, Nepal
The Khumbu Icefall is part of the oft-traveled path to Mount Everest – but it is also one of the least explored places in the world. Although thousands of climbers each year use ladders and ropes to climb over the icefall, the icefall itself is largely unventured due to its danger.
In 2014, an avalanche swept 16 Nepalese climbers into the depths of the icefall. Once you find yourself in the icefall, it is impossible to get out — as a result the Khumbu Icefall is one place nobody wants to visit.
