Machu Picchu, Peru.

WPI is best known for extensive scientific research at the ancient Machu Picchu site near Cusco, Peru, and annual Machu Picchu calendars.  WPI directors have done research at Machu Picchu since 1994, performing studies to determine the Inca’s agricultural practices, drainage techniques, hydrologic and hydraulic abilities, planning capabilities, construction methods, and even the existence of a previously unchartered Inca trail. WPI tested pollen types from Machu Picchu to determine the likely crops, medicinal plants and other foliage existing there during the time of occupation. WPI’s most recent field trips to Machu Picchu involved the discovery of more trails.
