Memorial at Mount St. Helens

Mount St. Helens is one of the most fiesty volcanoes on the planet. It is certainly one of the most active volcanoes in the United States. Situated in Washington’s Cascade Range, this stratovolcano is known for its explosive and frequent eruptions. Mount St. Helens has produced lava flows, towering lava domes, and erupted roiling ash clouds and pyroclastic density currents. Out of all of Mount St. Helens’ eruptions, one event in particular has branded itself into our memories: the eruption on May 18, 1980.

May 18, 1980

It was a quiet and sunny Sunday morning in Washington. Birds were singing in the thick forest and trout were splashing in the Toutle River. Elk roamed through the underbrush. And Mount St. Helens conical peak dominated the landscape.

Since March 1980, frequent earthquakes had rattled the volcano and surrounding landscape. Several small eruptions of gas and ash had occurred at the summit in recent weeks. More startling was the way Mount St. Helens had begun to deform. A tremendous bulge had formed under the north slope of the mountain in a matter of weeks.

Scientists and local government officials had never seen anything quiet like it. They understood that Mount St. Helens was active, but the last eruption had been in 1857. No one alive had witnessed the potential power behind the volcano. They frantically studied the mountain and try to predict what type of eruption the volcano would produce – and when.

Monitor Ridge – Part 2

Three steps. Two.  One.  Suddenly, Mount St. Helens’ summit crater stretched wide open in front of me.  The rim of the crater curved around to the north like eagles’ wings.  An enormous lava dome that dwarfed everything around it sat perched in the heart of the mile-wide crater.  The lava dome itself sat steaming happily away, tendrils of the white steam curling up toward us.  The sharp scent of sulfur – like rotten eggs – made my nose sting.  

We had made it!  I clung to my husband, brother, and sister as we cried victorious tears.  Jason, Paul, and Alex had each been overwhelmingly patient and kind to me on that hike. Twenty-four hours before, none of us imagined we’d be standing there together.  But there we were!  Successful because of each other’s patience, love for each other and for the volcano, and because of God’s grace.

Happy Thursday my friends! Another week has blazed by in the blink of an eye! I wanted to backtrack a little today and go back to a video I took at Mount St. Helens’ Loowit Viewpoint. This view is facing north, with the volcano at my back. You can clearly see the distinct lack of forest and rocks scraped bare of foliage from the 1980 eruption. All of the trees you see now have grown in the years since the blast.

After years of hoping, dreaming, and planning, the morning of August 4 found the four of us driving down the Spirit Lake Memorial Highway in search of mighty Mount St. Helens.  My three partners in crime and I had explored the river valleys and Forest Learning Center on our way toward the volcano.  But now, the time had finally come for me to meet Mount St. Helens face to face.  No more reading, research, or hoping to catch a glimpse out the airplane window. Today I was just a girl, standing in front of a volcano, asking it not to blow me into the stratosphere. At least not until I’d had a thorough chance to explore its slopes!
