MOUNT ST. HELENS, Wash. –The Johnston Ridge Observatory at Mount St. Helens is reopening for the season this weekend. That's just in time for the 30th anniversary of the volcano's epic blast. The visitor center re-opens with new short films and exhibits.
The Johnston Ridge Observatory is the closest visitor center to the crater of Mount St. Helens. This spring, highway crews plowed away snow to allow contractors to get in early to freshen up the displays. Monument scientist Peter Frenzen wanted the exhibit material to reflect technological advances in volcano monitoring.
