20,000 ft.». July 23rd: »At two o'clock we reached a point at least 23,000 ft.
above sea-level». If they had continued they would have been forced to spend a
night »on the exposed ridge probably at an altitude of 24,000 ft.», so they decided
to descend the southern slope of a ridge, which, for a thousand feet, was performed
on an avalanche. July 24th they had to descend several rock gullies before they
could walk up the glacier. The bivouac this night, on the upper part of the glacier,
was at an altitude which in their opinion was over 23,000 ft. And he adds: »It
is interesting to note that this is in any case the highest spot at which any one
has ever attempted to pass the night.»¹
During the night of July 25th, they continued and were stopped by a crevass
at an altitude, »which may have been over 24,000 ft.». They vertical distance from
the top he estimates of 1,500 ft., so the edge of the crevass cannot have been over
24,000, as the height of the Gurla is 25,350 ft. He says:² »It really does not matter
what the exact altitude was». But it would have been of value to know of what
kind of rock the highest mountain in Tibet is built. STRACHEY gave us some very
interesting communications from as near as he was able to approach the Gurla-
mandata. And I approached the mountain in the mouths of two of its northern
valleys, as has been related in Vol. II, p. 157.
Dr. Longstaff is right in giving the highest praise to the STRACHEYS' map,
illustrating their journey of 1846, 1848 and 1849.³ He says⁴ that this map gives
a more correct representation of the Gurla group than that contained in the latest
sheets of the G. Trig. Survey transfrontier series. »The huge southern glacier does
not exist as shown in the latter. This locality lies well to the south of Major
Ryder's recent survey; in fact, we were the first to see this side of the moun-
tain, though the northern glaciers are plainly visible from the neighbourhood of
Mansarowar Lake.»
I cannot judge in this matter as I have never been to the southern side of Gurla.
The map of the Stracheys, mentioned above, has two glaciers on the southern side
of Gurla. My preliminary map⁵ relied for these parts on RYDER'S map, and there-
fore a huge glacier is entered. This will have to disappear if the STRACHEYS' and
