The legislature recognizes that winter recreational activities are part of the folk tradition of the state of Washington. Winter recreational activities serve to turn the darkness of a northwest winter into the dawn of renewed vitality. As the winter snows dissolve into the torrents of spring, the Columbia river is nourished. The Columbia river is the pride of the northwest and the unifying geographic element of the state. In order to celebrate the river which ties the winter recreation playground of snowcapped mountains and the Yakima, Snake, and the Klickitat rivers to the ocean so blue, the legislature declares that the official state folk song is "Roll On Columbia, Roll On," composed by Woody Guthrie.
