The valley bottom of Yarma-Nubra is elevated 11,700 feet at the foot of the glacier that fills its upper end, close below the Turkish watershed, and 10,400 feet at its debouchure in Mid-Nubra, being a slope of 1,300 feet in a length of 55 or 60 miles, or a little more than 20 feet per mile.
In one or two instances also they are diminished or almost absorbed by running over a sandy bed; as the river of Hanle, which is fuller in its thirtieth mile at Tara Sumdo, than in its fiftieth at Hanle Gunpa, and reduced almost to nothing at its debouchure in the eightieth mile at LomaSumdo; and the river of Kumdan, which, 15 or 20 miles below its exit from the glaciers, is almost entirely lost in sand and gravel for as much further, but then comes up again, and regains its former volume.
