Note 16 — Chapter V · FROM TASHILHUNPO TO YAMDO SAMDING, AND THENCE TO LHASA.

After following up the river for a while, we ascended the Karo la,16 a lofty plateau from which we could distinguish to the north-east the snow-covered slopes of the Noijin kang-zang (or Noijin norpa zang-po and Kang zang-po). The plateau of the Karo la is called Oma tang, or “milky plain,”17 as is also the little hamlet near the summit of the pass. On this plateau, which is about five miles broad where we traversed it, there is fine grazing, and we saw numerous herds of yaks by the sides of the little streamlets which meander over its surface, the one flowing westward becoming the Nyang chu; the other flows to the east, and is called the Kharnang-phu chu, and along this the road led. On the summit of the pass I noticed a species of thorny shrub, the like of which I had not seen in any other part of Tibet; the thorns were quite long, and the stem and leaves of the plant of an ash grey colour.
