Summer snow. Even 4x4 jeeps needed a cable
to get out of the muddy snowfield.

Drilling on a slippery day (these Tertiary
red sediments are now at 5,500 meters above sea level!)

Our Chinese colleagues help collecting samples.

Tricky river crossing.

Wild donkeys running on the plateau (no human
beings live there).

Here at an altitude of 4767 meters the Chinese
characters say "the mouth of Kun Lun Mountain."
