Annapurna Sanctuary, Nepal
In mid-May 1999, alone on my last morning in the Annapurna Sanctuary, I tramped along the moraine below Annapurna Base Camp. The sun reflected off Machapuchare, the distinctive fish tail peak, at the bottom of the valley. Tharpu Chuli flanked me on the left, its 6000 meter crown glistening with fresh snow. No clouds covered Annapurna’s summits behind me or obscured the immense sky. The trail meandered from 13,500 feet to 12,000 feet. The low-oxygen air, like a drug, rendered the sapphire sky in vivid contrast to the silver cliffs, the white snow, and the wild crocuses that burst from south-facing patches in happy pink dots.
