Johnston Ridge Observatory:
Mount St. Helen's Crowning Jewel
Located at the end of State Highway 504 (52 miles east of Castle Rock), in the heart of the blast zone, the observatory hosts interpretive displays that tell the biological, geological, and human story of Mount St. Helens. Visitors to JRO can enjoy multiple award-winning films, listen to ranger talks, observe the landscape, purchase souvenirs, set off on a hike, or get a light lunch from the food cart. Check the MSH hompage for information on the annual summer Music on the Mountain series held throughout summer at the JRO outdoor amphitheater (in partnership with the Cowlitz County Economic Development Council and the Mount St. Helens Institute).
