The term "orejón" comes from the historical chronicle Relación de la Alta y Baja California (1598)[2] written by Rodrigo Montezuma, a man of New Spain.
His work made reference to the Columbia River when the Spanish explorers penetrated into the actual North American territory that became part of the Viceroyalty of New Spain.
It is also possible that the American territory was named by the Spaniards, as there is a stream in Spain called the "Arroyo del Oregón" (which is located in the province of Ciudad Real), or that the "j" in the Spanish phrase "El Orejón" was later corrupted into a "g".
Another early use of the name, spelled Ouragon, was by Major Robert Rogers in a 1765 petition to the Kingdom of Great Britain, seeking money to finance an expedition in search of the Northwest Passage.
[8] Why Rogers used the name has led to many theories, which include these: Others have speculated[20] that the name is related to the kingdom of Aragon: the major part of the Spanish soldiers who conquered the West Coast from California to Vancouver Island in the 18th century were in fact from Catalonia, a principality of the ancient Crown of Aragon in Spain.
