Sven Anders Hedin, Trans-Himalaya: Discoveries and Adventurers in Tibet…
“ The boundary between the two expanses of blue is sharply marked by an irregular bright white line; for what we see before us is the snow-covered crest of the Himalayas, and behind it lies India with its eternal summer. These are the most northern chains of the Himalayas, on the frontier between Tibet and Bhotan. Between them and the dark grey crest, comparatively near to us, yawns an 279 abyss, a huge fissure on the earth’s crust, the valley of the Brahmaputra or Tsangpo. The river itself is not visible, but we feel that we are now not far from our destination. ”
