William Augustus Brevoort Coolidge, 1911 Encyclopædia Britannica, Volume 9… (1911)
“ Yet, owing to its great elevation, the scenery of the Upper Engadine has a bleak, northern aspect. Pines and larches alone flourish, garden vegetables are grown only in sunny spots, and there is no tillage. The Alpine flora is very rich and varied. But snow falls even in August, and the climate is well described in the proverb, “nine months winter, and three months cold weather.” The villages are built entirely of stone (as also in the Lower Engadine) , chiefly to guard against destructive fires that were formerly frequent in this narrow, wind-swept valley. ”
