Colca Valley Andenes
Colca Canyon is a canyon of the Colca River in southern Peru, it is promoted as the "world's deepest canyon."
The valley presents one of the most intensely-terraced landscapes in the world, continuing for many kilometers downstream.
In this whole region the beauty of the landscape is formed by "andenes"(series of steps on the hills used for sowing, technique used from the times of the Incas, some with artificial irrigation and others for effects of the rains.)
