On Johnson's map E 57 has an altitude of 21,767 feet, and E 58 21,971.
These are probably identical with Stein's peaks of 21,750 and 21,960 feet, and here
both maps agree tolerably. The two peaks are situated quite near the Camp of
Kara-kash, the height of which is given as 15,491 feet,¹ and two ascents of resp.
6,276 and 6,480 feet would not be too much for a trained surveyor who had 20
days at his disposal. This lapse of time would also be sufficient for an additional
excursion of 50 miles to E 61 and an ascent of its 8,399 feet above Kara-kash.

Provided that E 61 is identical with Stein's Muztagh (K 5), as has been main-
tained, both having an altitude of 23,890 feet, and provided that the part of the
Yurung-kash which is dotted on Stein's map is approximately correct, there is no
physical possibility to travel from the Kara-kash camp of Johnson to E 61 without
crossing the Yurung-kash. Neither is it possible for a man who by some curious
roundabout way to 82° east has reached the top of E 61, to be quite blind to the
existence of the enormously deep-cut valley of the river just below his feet and to
the south of his standpoint. But on Johnson's map there is no sign of the Yurung-
kash, except to the north of the Muztagh Range of the Kwen-lun.² Therefore, and
as Johnson was known to be a very able surveyor, and as it would be absurd to
doubt the correctness of Stein's map, there remains only one way of explaining the
puzzle, and that is that Johnson never ascended E 61 or Muztagh. The general
discrepancies of his map of which Stein speaks are far more serious. He makes,
for instance, the uppermost Yurung-kash flow from west to east, north of the Kwen-
lun ridge; in reality it flows from east to west, south of the same range. From his
E 61 he has drawn straight south a mighty meridional mountain range between 36°
and 35° North. lat. in a region where the ground, to a traveller from the west to
the east, is perfectly level. This and other facts do not in the least diminish the value
of his courageous feat, and mistakes are made even by the best trained explorers.
