USGS photo of Mt. Saint Helens. See smaller version.

Caption: Plumes of steam, gas, and ash often occur at Mount St. Helens. On clear days they can be seen from Portland, Oregon, 50 miles (81 kilometers) to the south. The plume photographed here rose nearly 3000 feet (1000 meters) above the volcano's rim. The view is from Harrys Ridge, five miles (8 kilometers) north of the mountain. (May 19, 1982, by Lyn Topinka, USGS)
