where is Krakauer at the beginning of this selection?

The selection begins with Krakauer standing on the summit of Mount Everest.

Straddling the top of the world, one foot in China and the other in Nepal, I cleared the ice from my oxygen mask, hunched a shoulder against the wind, and stared absently down at the vastness of Tibet. I understood on some dim, detached level that the sweep of earth beneath my feet was a spectacular sight. I'd been fantasizing about this moment, and the release of emotion that would accompany it, for many months. But now that I was finally here, actually standing on the summit of Mount Everest, I just couldn't summon the energy to care.
