46 years ago today, the eruption of Mount St. Helens rocked southwest Washington and transformed our region. The 1980 eruption caused the largest terrestrial landslide in recorded history and reduced the mountain’s height by more than 1300 feet!
The blast blocked out the sky, flattened and scorched 230 square miles of forest, changed the course of rivers, and blanketed communities in falling ash.
Visiting Mount St. Helens National Volcanic Monument today, you can see firsthand the incredible power of Cascadian volcanos, as well as the stubborn resilience of life as ecosystems bounce back in the shadow of the Cascade’s most active volcano.
Early bird pricing ends at midnight! Come get inspired and support local conservation at the UNDERSTORY NW FILM FEST: comming to The Kiggins Theatre for one night only, Thursday, May 28th at 6:30.
