These images show the area around Mount St. Helens, in southwestern Washington, before and after its eruption of May 18, 1980. In these false-color images, forest appears as bright red interspersed with patches of logging. Snow appears white, and ash is gray.
The cities of Vancouver, Washington, and Portland, Oregon, are visible in the southwest of the zoomed-out images, north and south of the Columbia River, respectively.
