The difficulties to follow the path of a caravan.
I must start by an anecdote. The Paris-Dakar is a race divided in two kind of participants, professional drivers, cars “full equipped”, Air conditioned motorhome to receive a massage before a good night rest, and the others, purely amateurs, who have nothing of that. And several years ago, professional drivers had a GPS (but without waypoints a GPS is, more or less, a compass), but not amateurs. In one of these navigation stages, in the Sahara, an amateur, from Madrid, arrived more than half an hour earlier than the professional riders who had become lost, all together in the dunes. And this guy navigated perfectly, with a mere compass and a watch, not only this time, but in general. And the journalist interviewed him, and he said: ” it is not so difficult, you must follow camel dung, and you follow the path of the caravans”.
Well, this is what I did today, not with camel dung (in the Takla-Makan they use it, when dry, as combustible, argol, so probably I had not find a lot), but with the beads that Peter Fleming left in his “News from Tartary” book, as well as the information everybody (at least, Peter, Ella, and Lattimore) shares: a caravan starts at 6 in the morning, and walks for 8 hours approximatively, doing 30 km per day… well, this is not exactly true, average is less than that (due to cold, to water points, or for no stated reason), but sometimes they put two stages in one day (a four hour stop, and a night march) so they increase the average.
They made an approach from Tangar until meeting the caravan of the Prince of Tzoun, near the East bank of Qinghay Lake (Stage 4, Valley of Daotang River). Their second stop was a Lamasery, that can be found on Google Earth with Panoramio
They walked three days on the South Bank of Kinghai Lake, roughly in a NW direction, until Stage 7, then they take a SW direction passing on the North Bank of Chakayan Lake (the Salt Lake in Peter’s text, Stage 10), and, after two mountains passes, they arrive to the Tsaidam (after a few hours of Stage 13), and they cross the Dulan desert (Stages 14, 15 and 16) partly at night, because they are already near their goal.
With all this background I located Dzhounchia,(Stage 17, they arrived there on April 12, 1935), which is at
and this position agrees with the three camel days that Li, their interpreter, says are needed to reach Nomo-Khantara, which is 80 km away

note: I may upload also the Google Earth file, with includes the distance between stages, but I am searching a Map application.
