The mighty Columbia River

On the evening of May 11, 1792, American merchant sea Captain Robert
Gray of Boston (above) sailed into the river that he named “Columbia” in
honor of his ship, Columbia Rediviva, becoming the first recorded explorer
to navigate the river.The voyage was eventually used as a basis for
America’s claim on the Pacific Northwest.Gray spent nine days on the
river trading fur pelts before leaving.

Depictions of the private vessel named Columbia Rediviva used to travel the
approximate 13 mile trip up the Columbia River.
