Building Machu Picchu
“The high Andean saddle of Machu Picchu, c. 1470. Inca stonemasons fit polygonal blocks for the Temple of the Sun. Foreground shows masons with stone hammers and ceramic plumb bobs; midground reveals terraced fields of maize and quinoa carved into the cloud forest; Huayna Picchu's peak rises behind through swirling mist over the Urubamba gorge.”
