30 Years Ago: The Eruption of Mount St. Helens

From the Washington State Digital Archives

Today, May 18th, is a red-letter day in Washington State. Thirty years ago today, at 8:32 AM, Mount St. Helens erupted. "The eruption touched off the greatest landslide ever, ripping off a large part of that enormous dome, blowing out 3.7 billion cubic yards of mountaintop and spewing ash that girdled the globe a number of times. The blast zone was 230 square miles; 57 people, including the crotchety Harry Truman, lost their lives." [Washington Secretary of State blog]

At the time, I was a 13-year-old eighth grader, living with my parents and younger siblings about 10 miles north of Colville in Northeastern Washington. It was a Sunday and I'm sure we went to church that morning. I don't remember exactly when or how we heard the news that the mountain had erupted, but at the time, it wasn't a surprise. Scientists had been monitoring the mountain for some time, as it was showing signs of volcanic activity. But it wasn't until we came home after church and turned on the TV that we realized the effect the eruption was having on Eastern Washington, especially those communities lying directly in the path of the ash cloud, like Ritzville and Spokane.

Spokane, Washington is the largest urban area between Seattle and the Twin Cities, Minnesota. Eighty miles to the south of my home, it was where all local television news was broadcast for my small rural community. And what a broadcast the local stations had for us! The reporters told how everything became deathly quiet, the sky turned dark by three o'clock in the afternoon with street lights coming on, and then the ash fell. Like snow it came down, up to six inches' worth, but much more serious. People with respiratory problems were affected, and so were vehicles. The fine particles of ash clogged air filters in automobiles. Air filters and face masks were soon sold out everywhere. Snow plows had to clear the streets, and the Spokane Police Department had special filtration systems in place on the front of their vehicles making them look like strange space machines. In fact, the city took on the look of a moonscape, gray and dusty. Schools, colleges, and even businesses closed for a week, and as in times past and future, the community came together to help each other out. (Check out photos from the local paper here.)

But up in the Colville area, the effect was much less severe. I took some photos of my parents' Jeep which showed just a light dusting of ash, as well as a panoramic shot of the mountain across the valley from their home. Normally easily visible even on a cloudy day, it appeared to be obscured by a cloud--not of rain, but of ash from a mountain some 400 miles away!

Meanwhile, on the "other side of the mountains," as we like to say here in Washington, my husband-to-be was soundly sleeping. A 23-year-old college student in Vancouver (Washington, not British Columbia), he had been staying awake for hours on end, hoping to be able to witness the highly-anticipated event that the media and scientific world had been predicting. A beautiful dome in the snowy Cascade range which stretches from Lytton Mountain in British Columbia to Lassen Peak in Northern California, it was in the company of such notable peaks as Mount Baker, Mount Rainier, Mount Adams, Mount Hood, the Three Sisters, Mount McLoughlin, and Mount Shasta.

Exhausted after waiting, he fell asleep and slept through the blast and concussion, even though it was only 50 miles away! Only a small amount of ash fell on Southwest Washington, as the blast and then the jet stream carried it away to the northeast.

Many residents of Washington can today show you their jars of Mount St. Helens ash, the fine particles like baby powder, from which ash trays and other mementos were made. Even today, if you look carefully, you can see the ash here and there throughout Central and Eastern Washington. Certainly, if you do any digging, you'll come across the layer. The ash, although devastating on many levels, did enrich the soil in Eastern Washington.

I tried to find the photo of my one trip several years ago when we came rather close to the now barren mountain after visiting my in-laws. It appears the photo has been damaged in my computer crash a year ago, so I won't be able to post it here. But I'll never forget driving up and pulling over to take a good look at the remains of the scorched mountain. At that time, it had been smoking again. Even at 10 or 15 miles away, it looked ominous, eerie, ghostly. Chills went up my spine and I urged my husband to turn around quickly and return to Vancouver. It took no strong imagination to understand how the ancient natives felt about these volcanoes. Sleeping giants, monsters, evil spirits...the legends live on.


Here are more memories shared by others in the Inland Northwest.

Thanks very much, Miriam, for marking the anniversary and sharing your memories of the event. Although I was on the other side of the world at the time, I was in the first year of study for my geology degree, so of course I saw it on TV and read all about it in the newspapers - a fascinating story of earth-building and destruction at the same time.

The anniversary has been marked by an article in the May issue of National Geographic magazine about how the blast zone is regenerating, accompanied as usual by some great photographs which you can see online here. It has been of particular relevance to me, because I'm currently doing a project on ecosystems which developed in just such a post-volcanic environment here in New Zealand, but after the massive Taupo volcanic eruption which happened in about 185 A.D.

Regards, Brett

Brett, you are the second geneablogger to recommend the National Geographic issue; Amir Dekel also did. Thanks for the recommendation...I'm headed over to take a look!

Though only five at the time, I do remember this. The explosion dominated the Boise, Idaho television stations viewing area as well. We lived on the Idaho/Oregon border on the banks of the Snake River and we had our share of ash blow our way. I remember my mom's windshield was covered with a layer of the finest looking ash. Our skies were grey and murky and we had fiery orange sunsets for years afterwards.

I, too, will have to go look at the National Geographic link. I remember spending a great deal of time in science classes for years to come on the subject of the Mt. St. Helens explosion.

There isn't a year that has gone by since 1980 that I don't think about that day. I was a student at WSU in Pullman and experienced the ash fallout and resulting aftermath first hand. The university was closed for several days something that even snow couldn't do. Sudents coming into our dining hall from other dorms had to wear layers of clothing to protect against the ash. Some even dressed up like Star Wars storm troopers and even Darth Vader complete with light sabers!

And yes, I still have my container of ash after all these years. I know exactly where it is.

I'm glad Brett mentioned the May National Geographic. I have it but have been so busy I haven't read it yet.

Tracy and Michelle, I'm always interested in hearing about those Inland Northwest connections! Thanks for sharing your memories!
