The Riddle of the River: How David Thompson Explored and Mapped the Middle and Upper Columbia River
The Columbia River forms one of the great North American drainage basins covering much of the states of Washington, Oregon, Idaho and the Canadian province of British Columbia. As recently as 1800 little was known of this vast region and the complex topography of the middle and upper Columbia River basin. Spanish explorers pushing up the coast from their established posts in New Spain (now Mexico) were likely the first Europeans to see the mouth of the Columbia. In 1775, Spanish explorer Bruno de Heceta sighted the mouth but was unable to enter due to strong currents. It was soon after shown as Entrada de Hezeta on composite maps of Spanish explorations of the coast prepared by Bodega y Quadra in 1775 and 1791.
