THE CHANG-LA-POD-LA PASS.   345

Arniri-rung or Ami-rz-rung. On P. 275 and 276, Vol. III, there are some photographs and sketches from this region.

On April 201h, the distance to Camp CXL V, Chomo-sumdo, is 19.2 km. due west. The rise is 271 m. or 4,795 m. at Camp CXLV. The rate is I : 7 I . The Pashu-tsang-po, streaming from west to east, is no doubt situated in the tectonic

valley which separates the two ranges of Chesang-la and Shib-la from one another.

On April 2 IS', we crossed the great continental water-parting in the pass Chang-la-Pod-la, or »The Pass between Northern and Southern Tibet.» Its altitude is 5,572 m. The ascent from Camp CXL V is, therefore, 777 m. The distance being 9.2 km. W. N. W., the rate is 1 : 11.8. On the northern side we had 6 km. W. N. W.

to Camp CXL VI, Cha-oktsang, where the altitude is 5,233 m. or 339 m. below the pass, the rate thus being I: 17.7. On both sides the water-parting crest is thus very steep, and, as usual, steeper on the southern than on the northern side of the range.

Some photos were taken from the pass itself. They are to be found in Vol. III between p. 276 and 277, and should be compared with Pan. 166, Tab. 3o. The latter is interesting as it shows the whole horizon as seen from Chang-la-Pod-la. The view, however, is not at all far-reaching, and nearly the whole panorama represents hills in our immediate vicinity and belonging to the water-parting crest itself. Only to the N. 6o° E. there is a distant range, probably the western continuation of the one of Shib-la. To the S. 55° E. and in the direction of Korso is the road by which we climbed up to the pass. To the N. 35° W., in the direction of the Mug- balung valley, our road goes down from the pass, soon turning to the left around the rocky corner and continuing westwards. Pan. 169, Tab. 31, is taken from Chaoktsang and gives a view of the very near mountains.

Having crossed the pass we are on the Chang--tang or Northern Plain. Still the descent is comparatively steep, much steeper than in the lower 11A-chu valley.

We had 14.7 km. W. N. W. to Camp CXLVII, Kyam-dam, on Aril 22nd, and descended 183 m., or to 5,050 m., being a rate of 1 :80.

The Panorama 171, Tab. 31, taken from Lapsen-tari about halfway between

Camps CXLVI and CXL VII, is from three points of view of a certain interest. To begin with, it has the unmistakable Chang-tang character, more flat, more open, and with more distant views than the Mü-chu valley we have left behind. Secondly, it gives a perspective, to the S. S. E., south and S. S. W., of the range we crossed in the Chesang-la. Finally, it shows to the N. 55° W. the first glimpse one gets of

the Targo-gangri from this road. A photograph of the »hla» at Lapsen-tari with a view to the N. 55° W. is to be found between pages 28o and 281 of Vol. III, though the peaks of Targo-gangri, by reason of the great distance, do not appear on the photo.
