The Doker-La

Not doing it on this trip, but here's a previously unpublished pic of the pass from below the western, Tibetan, side (see red arrow). The pass marks the border between Yunnan and Tibet, and is also a very sacred place for Tibetan Buddhists. As you can see it is very steep near the top (I freaked out) and has a track of 108 zig zags down to the valley basin. There is also a rope in place for pilgrims to hang on to during icy/snowy weather.
And here is a view of the Doker La looking down (after the worst bit over). If you look carefully at bottom right you can see the rope and my two son plus guide descending:
