Pensi La

Pensi-la (Pensi Pass) is a mountain pass in the Ladakh union territory of India, which is known as the Gateway to Zanskar. Pensi La is 4,400 m (14,436 ft) above sea level and connects the Suru Valley region to the Zanskar Valley region. The summit at this end of the Suru Valley, the only peak which can be seen, is 7,012 m (23,005 ft) high, while the mountain to the north is 6,873 m (22,549 ft). The pass is about 25 km from Rangdum Monastery.
To the west of Pensi La watershed flows the Suru River, an important tributary of the Indus which meets at Kargil. The Drang Drung Glacier to the eastern flank of Pensi La is the source of Stod or Doda River which flows into the Padum Valley, and joins with Tsarap Chu to form the mighty Zanskar River.
"The descent from the Pensi La into the Stod Valley [in Zanskar] is steeper than the climb up from Rangdum Gompa, but not too difficult. The road winds about with many hairpin turns, which can be cut across on foot, to the river below. Wild rhubarb can be seen growing on the slopes. The generally used trekking route follows the road on the left bank of the Stod (or Doda). . . . The grass at the foot of the Pensi La furnishes a good pasturage and this is a fine camping spot.". Pensi-La is also the gateway to the Padum, the headquarters of Zanskar sub-division of Kargil district. A 240 km road connecting Kargil town to Padum, through the Pensi La remains open for a brief 5 months, between May and October.
Before the modern road was built, the pass, apparently, used to be open only three months of the year because of heavy snows.
