Lost On Everest - The Search For Mallory & Irvine. 1/5

On June 8, 1924, George Mallory and Andrew Irvine left their tent high up on the slopes of Mount Everest and climbed into history. They were seen at 12:50 pm just 800 feet from the summit and "going strong for the top". Within minutes, Mallory and Irvine had disappeared in a snowstorm and were never seen alive again.
