This seldom seen map details the basin and valley of the Amazon River. The range extends from the Pacific in Peru and Ecuador to the Atlantic and the mouth of the Amazon at the I. Marajo. The watershed is shown in great detail. Lieutenant Herndon made this exploration and the resulting report under the direction of the U.S. Navy Department. He journeyed through parts of Peru, Bolivia and Brazil for nearly a year and went on to become the captain of the ill-fated Central America which sank in 1857 with a load of gold and newly minted gold coin from the Carson City mint. The gold, valued at more than a billion dollars, was recovered in a deep water project completed in 1989.
