When I was growing up, if anyone ever thought to ask me if there was something I’d like to witness but would never get the chance, I might have said “a volcanic eruption.”
I grew up in Portland, Ore., about 50 or so miles west of a chain of volcanic peaks along the Cascade Range. Most of the peaks were considered to be in various stages of dormancy. Some of them are extinct. They’ll never erupt again.
One of them, though, just northeast of our city, was considered “most likely” to erupt. Who would have thought we’d actually witness it.
Thirty-five years ago, on May 18, 1980, good ol’ Mount St. Helens blew apart in a cataclysmic blast no one likely ever thought they’d witness.
It was a Sunday. It was overcast in Portland that morning, so we didn’t actually witness the ash cloud blown 50,000 feet into the air over Washington state. Aerial photographers took plenty of pictures, though. It was a huge day in the lives of those of us who grew up looking eastward along the Cascades.
Portland’s signature actually is Mount Hood, the highest peak in Oregon. To the north of Mount Hood is Mount St. Helens.
Prior to the blast, Mount St. Helens cut an impressive and pristine figure against the sky. It looked almost geometrically perfect. Some folks called it the “Mount Fuji of the Americas,” as it bore some vague resemblance to Japan’s famous — and perfectly shaped — peak.
The cataclysm took care of Mount St. Helens’s appearance. It blew about 1,500 feet of dirt and rock off the top of the mountain, scattering it as part of that pyroclastic flow of hot gas and ash that ripped through the Douglas fir forest, filling Spirit Lake with fallen timber.
The mountain had been rumbling for a couple of months prior to the blast. I had the thrill of a lifetime when I flew over the summit in a private aircraft to take pictures of the crater’s early beginning. One of my colleagues at the paper where I worked drove that day in March to interview individuals who were monitoring the mountain’s activity for the U.S. Geological Service.
My colleague, Dave Peters, caught up with a young geologist named David Johnston, visited with him about what he was witnessing as the mountain started rumbling. Dave returned and filed a fascinating feature about Johnston and others he met that day.
Johnston would die in the blast a few weeks later as he was perched on a ridge that would be renamed in his memory. As the once-gorgeous peak blew apart, Johnston yelled into his radio to the USGS headquarters: Vancouver, Vancouver … this is it!
And then, just like that, he was gone.
That amazing day is etched in the memories of those of us who were aware of the volcanoes that dotted our skyline to our east.
I doubt any of us ever thought we’d witness what we saw on that Sunday morning 35 years ago.
Who knew?
