Looking down on Macchu Picchu with Huanu Picchu in the
background. Notice the stone walls of the huts, their thatched roofs decayed long ago. A guess when they were
built, about 500 years ago.
You cannot see Macchu Picchu from the canyon below.
It went undiscovered until the early part of the last century. I think professor Bingham saw it when he flew over it in the 20's.
