1. Flashlight on top of 200 mm of snow (8 inches) on the tent. Turned on - it worked.
2. Military puttees -- two of them.
3. 11th pair of skies, found outside the tent. The hikers had nine (arranged under the tent) and a tenth pair was in storage.
4. Bodies were moved after death.
5. A piece of a broken ski 20 m from the tent.
6. A large circle of swept snow, larger than that of helicopter rotor blades.
Put these together, one could surmise: Someone arrived by helicopter, wearing military puttees, using skiis, left a Chinese flashlight on the tent, and moved some bodies.
