Mamoré River
In 1901, the Peruvian Government created a committee to explore the nation's rainforest. Don Juan Villalta led an expedition along the Tambopata River, departing from Sandia. Villata officially founded Puerto Maldonado on 10 July 1902, as a station at the confluence of the Tambopata and the Madre de Dios rivers. He named the port after Faustino Maldonado, of Tarapoto, who had explored the Madre de Dios in 1861 and drowned in the rapids of the Mamoré River.
