The same year GRAHAM SANDBERG makes the Kara-korum, with the Kara-
korum Pass, continue straight to the east, to 85°, and calls it »Snowy Range seen
by Wellby». But the map¹ on which this extraordinary information is given is very
rough and cannot be treated seriously.
During the summer of 1903 Captain C. G. RAWLING, together with Lieutenant
HARGREAVES and the sub-surveyor RAM SING, carried out his memorable Exploration
of Western Tibet and Rudok.² Its chief object was the extension of Captain DEASY's
survey made in that direction in 1896.
RAWLING took the way of Lanak-la into Tibet and arrived at the Sumjiling
Plain, which had been traversed by BOWER, DEASY and WELLBY. The way to
Arport-tso was well known. Rawling turned south-east, keeping first south, then
north of Bower in 1890. Then he went due north following Deasy's track at the
Antelope Plain, which was the farthest eastern point reached by Deasy. From here
he returned to Yeshil-köl, where Hargreaves waited. Lungnak-la, 18,650 feet, was
found to be of »partly disintegrated granite». I went, in 1908, a little north of
Lungnak-la where everything was limestone.
Regarding the Shemen-tso he found that »at some former date it evidently
occupied a much greater area». It was bitterly salt. North of the lake was the
»Kiang Plain». From Rawling's map as well as from Deasy's, it is easy to see that
the mountains in this part of Tibet are arranged in a much more irregular way than
otherwise. »Largot Kangri runs roughly east and west, and from the east end of
that range the Aru-tso mountains run south». On the map, however, the former
stretches S. E., the latter S. S. E. which is more likely. Then he turned N. E. Of
a part of the way to Memar Chaka he says: »Great ridges of limestone lying at an
angle of 45° rose on either hand, while the bed of the stream was filled with immense
boulders of concrete.» The Memar Chaka was found to be bitterly salt; »signs were
plainly visible of the lake having been at some remote period about 80 feet higher
than its present level».
The »Deasy Group» was estimated at »well over 21,000 feet».
Regarding »Lake Markham» he made the following observation:
The water of the lake at its western end is fresh, but as one travels towards the
east the water becomes more and more impregnated with salt, until at its eastern end it
becomes undrinkable. At the time of our visiting Lake Markham there was no overflow,
the surplus water being apparently absorbed by the soil, or lost by evaporation. There
is, however, a narrow channel at the eastern extremity, which at this date was very dry,
but which bore evidence that at some season of the year the water escapes by this channel
and drains into the low-lying ground to the north, which is white with salt.
