Marker Text:   Here the Columbia River, the mightiest river flowing into the Pacific Ocean from the American continents, ends its journey. Native people have lived along the banks of this river and fished its waters for thousands of years.

Euro-American exploration of the river began in 1775, when the Spanish explorer Bruno de Heceta sailed within sight of its mouth. Treacherous waves breaking over the river bar prevented him from entering; nevertheless he placed the river mouth on Spanish charts.

Robert Gray, a Yankee sea captain, brought the first ship over the bar and into the river on May 11, 1792. Gray traded for sea otter and beaver pelts with the Chinooks, who received items in return that would ????? in their wide trading network. Before leaving, Gray named the river after his ship, the Columbia.

Later that fall, British naval lieutenant William Broughton traveled and charted 100 miles upriver. His commander, Captain George Vancouver, used "Columbia River" on charts he published in 1798. Seven years later, these charts helped the overland explorers Lewis and Clark confirm their exact location when they reached the mouth of the Columbia.
