FEATURE image: Mount Saint Helens today. The powerful lateral blast in May 1980 sent scorching hot ash and rock hurtling out of the mountain at approximately 300 miles per hour and resulted in toppling about 40% of the mountain’s height. “Mount Saint Helens” by jimculp@live.com is licensed under CC BY-NC-ND 2.0.

“Nobody lies about her lodestone any more. She burned and destroyed the whole park! Killed people too – what a pity! Only scientists are out there now. What’s there to see, dear? Isn’t it all in ruins?”

This is what the lady innkeeper told me in Portland, Oregon, before I set out in the car one early morning in July 1991 to visit the crater.

“It’s a pity she blew. It was such a pretty mountain before. WAS, I say. The kids loved camping at its base. It was so easy for them to get in and out. Then she blew and changed everything.”

I waved my good-byes and started the two-hour drive.

At 8:32 a.m. on Sunday, May 18, 1980, an earthquake followed by a landslide and near simultaneous volcanic blast changed forever – and in less than 10 minutes – a Cascades landscape of 230 square miles. Months before the unexpected blast, volcano watchers had camped near the mountain, including scientists and photographers, who were interested to gauge its recent unusual seismic and geological activity and capture what the mountain may do. Local property owners pressured authorities to be let back into their homes during this uncertain and, as it turned out, critically dangerous waiting period. Especially good weather brought out an extra contingent of weekend campers, backpackers and curiosity seekers to the mountain, many from Portland only 70 miles away.

Everybody I talked to during my 1991 visit remembered 83-year-old Harry Randall Truman who lived by the mountain for over half his life and refused to leave in the days and weeks before the May 18, 1980 eruption. Not sure whether the mountain would blow or not, Truman, who served in the U.S. military in Europe in World War One, resigned himself to the mountain’s fiery whims. When the 1000-story high burbling volcano finally did blow, the avalanche and blast buried Mr.Truman, as it did Spirit Lake, in 350,000 acre-feet of fire and ash  debris. Mr. Truman’s body was never recovered nor did he represent the only loss of human life in the eruption. 

Only a few months before my July 1991 visit the authorities had re-opened Mount St. Helens for the first time in more than a decade. It was named a National Volcanic Monument and deemed safe again for visitors. After Bear Meadow I followed the prolonged twisting road to past Ghost Lake, Meta Lake and Norway Pass until I reached Independence Pass. From its overlook I saw  for the first time the ashen slough that had been Spirit Lake. For years prior to May 1980 several camps inhabited the shore around the lake’s perimeter. There had also been various lodges around the oblong-shaped lake including the one Mr. Truman lived in. On May 18, 1980 Spirit Lake met the full impact of the volcano’s lateral blast. The sheer force of the blast lifted the lake out of its bed and propelled it about 85 stories into the air to splash onto adjacent mountain slopes. Despite the weeks of warnings about a potential eruption of Mount St. Helens, the sole film records of the actual event are in photographs.

At 8:32 a.m. on May 18, 1980 a 5.2-magnitude earthquake triggered the bulging north slope of Mount St. Helens to slice and fall away into the biggest debris avalanche in recorded history. This landslide was rapidly succeeded by the powerful lateral blast that sent scorching hot ash and rock hurtling out of the mountain at approximately 300 miles per hour, toppling and incinerating everything in its northward path. Fifteen miles away from the mountain temperatures reached Fahrenheit 572 degrees.

While in 2016 plant and animal life continue to recover and augment as it has for decades now,  my boots in 1991 crunched into a gray, dusty moon-like surface. From Spirit Lake to Windy Ridge I was confronted by trees flattened like toothpicks as far as the eye could see, and a cauldron emitting wispy white smoke. The base of the mountain is four miles wide. The journey had taken me from civilization and delightful wilderness into mile upon mile of  badlands. My bodily presence was miniature in an immense, silent, and deserted landscape, the scene only a decade earlier of the most powerful natural event in the Continental United States in over one thousand years. While I heard some people talk about this volcanic eruption as comparable in its destructive power to that of a detonated atom bomb, I know that sort of comparison is ludicrous. For all its destructive force, this is not a disaster as it contains, if one requires patience to believe it,  a natural benignity – or what scientists  call a natural disturbance on a grand scale which allows mankind to study the natural cycle of death and life in a landscape. An atom bomb provides none of that -it only bestows extinction and contamination.

Ash and gas, accompanied by lightning, ascended 15 miles into the air at the speed of a mile a minute. In a blast that killed 57 people – many of whom were there to study and record its possible eventuality – it also decimated approximately 7,000 large animals and 12 million salmon. No trees of dense forest were left standing within 6 miles of the summit. Rescue operations continued for days with varied success.
