In 1911, Hiram Bingham was on the expedition which resulted in him bringing to a wider world attention the Incan ruin of Machu Picchu. Romero pointed him toward Puquiura as the site of Vilcabamba, and Bingham discovered there the ruins of Rosaspata. He correctly identified Rosaspata as the Incan Vitcos rather than Incan Vilcabamba. Drawn by rumors of another lost Inca ruin in the lowland forest, Bingham ignored tales of a hostile plantation owner and dangerous Indians and proceeded onward. After a difficult three days of foot travel, he found the plantation. Its owner and the Asháninka or Campa Indians working there were friendly and helpful. They assisted him in cutting a trail through the jungle and two days later he found Inca ruins at a place called Espiritu Pampa. He found artificial terraces, stone houses, including a rectangular building long, a fountain, Inca pottery, and a stone bridge. But Bingham was running out of supplies and only spent a short time at Espiritu Pampa. Based on his brief observations, Bingham concluded that Machu Picchu was the Incan Vilcabamba. That opinion went largely unchallenged for 50 years.
