The Treasure Valley is the area of the Western United States where the Payette, Boise, Weiser, Malheur, Owyhee, and Burnt rivers drain into the Snake River. Treasure Valley includes all the lowland areas from Vale, Oregon on the west to Boise, Idaho on the east. Historically, the valley had been known as the Lower Snake River Valley or the Boise River Valley. In 1959, Pete Olesen, president of the valley's association of local Chambers of Commerce, coined the name Treasure Valley. Olesen said the name reflected the treasure chest of resources and opportunities that the region offered.
