The canyon is located in The Andes about 160km northwest of Arequipa.
With a depth of 3,270 metres, it is one of the deepest in the
world.
They
take their measurements from the mountain top to the bottom of the
canyon.
We visited the canyon as part of our 8-week around-the-world trip in May 2004.
Adult condors have a wingspan up to 4.2 metres.
They
were very graceful, only flapping their wings when they were flying out
of the area.
