condor cross, colca canyon

Attributes of the Condors:
They were silent. Condors were ugly but they fly beautifully. They can survive 14 days without eating. Their eyes were 8 times better than human. They are huge but they don't attack live animals (you have to be very dead to be eaten by the condors). So they were thought to bring the spirit of the dead to the heaven.

They pass the Condor cross to take a free ride of the thermal energy (so they can fly to 8km high).
