File:MSH82 st helens plume from harrys ridge 05-19-82.jpg


Plumes of steam, gas, and ash often occurred at Mount St. Helens in the early 1980s. On clear days they could be seen from Portland, Oregon, 50 mi (80 km) to the south. The plume photographed here rose nearly 3,000 ft (910 m) above the volcano's rim. The view is from Harrys Ridge, 5 mi (8 km) north of the mountain.
