The last known European explorer to arrive seeking exploration was British officer Percy Fawcett (1867-1925?) Percy's adventure was to travel up to the source of the Amazon river in Peru. He began his expedition in the Atlantic, immediately north of present day French Guiana, his route moving west toward the Pacific.
Percy Fawcett died during his expedition; his companions were ill and died in route to the Pacific. In 1927, explorers discovered tribes deep in the Amazon that held name plates & compasses belonging to Fawcett's expedition. His body was NEVER FOUND.
David Grann writes a fascinating book about Percy Fawcett and the Lost City of Z. Mr. Grann not only gives a historical narrative about percy Fawcett's expedition, but he takes readers on a journey of adventure and discovery as he retraces the expedition in the Amazon searching for clues himself!
