Cayley reconnoitred a route that went through the Changchenmo ranges ... if anything these new passes were higher than the ones they replaced, and the land in between them was also higher. ... The route had another advantage in that trade from British India could flow through Kulu via Changchenmo to Yarkand, completely bypassing the customs officials of the Maharaja at Leh."
