Random photo: Crossing the Doker La pass from Yunnan to Tibet

I think I posted this photo before but this as a recent higher res re-scan of the original 35mm slide. We have just crossed the Doker La and I am looking back (terrified) as we descend the steep and precarious switchback trail descending into Tibet. These guys are some strangers who are presumably doing the pilgrimage around the Kawakarpo Kora circuit.If you look closely you can see a rope running diagnonally from the pass at top right to bottom left. This is put there to assist pilgrims in descending when the pass is snow and ice bound. To descend by the path at such times would be suicidal.
