Bingham decided to organize another expedition to Machupicchu Peru

On his return to the USA, Bingham decided to organize another expedition to Peru. He arrived in Lima in June 1911 where he began to study the seventeenth-century chronicles of Antonio de la Calancha and Fernando de Montesinos. The writings of these two men first inspired Bingham to seek the last two capitals of the Inca, Vilcabamba and Vitcos. Leaving Lima in July, Bingham returned to Cusco from where he journeyed on foot and by mule through the Urubamba Valley, past Ollantaytambo, and on into the Urubamba gorge. http://ping.fm/T8IUN
