M. S. Wellby, Through Unknown Tibet
“ Our route, as far as we could make out, lay over a large open plain with but scanty grass, and far off we could see a hill standing out alone conspicuously, a useful landmark for us to march on to. Without a distinct feature to make for, the caravan would very often zigzag down a broad valley and perhaps cover a mile or two more of ground than was necessary. ”
