On May 1, 1999, my teammates and I discovered the remains of George Mallory high on Everest. Here, I reflect on that day twenty years later, once again on Mount Everest.

While it's always hard to be away, it's always good to be back.

Everest is hard, but saying goodbye is harder.

Of all sides of Everest - the south from Nepal, the north from Tibet, and the east, also from Tibet - it is the eastern approach via the Kama and Kangshung Valleys, which are the most stunning.
