The fort of Nangartse, on the trail to Lhasa in central Tibet.

In the courtyard of a Tibetan house, as seen from my window.

Crumbling watch towers dot the landscape along the trail to Lhasa.

A street in Phari, Tibet, sometimes called the "highest, windiest, dirtiest city in the world".

My Tibetan servant Pa-sang ("Friday"), with friends.
