One of the things that's a great visual reminder of how powerful this blast was is to see the mountain today versus prior to the eruption. 1/3 to 1/2 of the top half of the mountain was blown sky high, leaving behind a mile-wide crater and 3/4 of a cubic mile of debris.The top of the mountain is gone.
Pyroclastic Storm was the name of my junior high band.Day turned to night, ash rained from the sky and the eruptions created their own weather and some lightning occasionally. It was a real mess.

I believe it was an earthquake that got the ball rolling as opposed to volcanic activity alone.
That's really cool Faust.See the eerie glacier caves carved by Mount St. Helens’s fiery breath (A free Nat Geo account is required to read this article)
added the picture.my brother just posted a picture of us camping on Spirit Lake on the mountain- had to be a few years before it erupted.
we went two or three years in a row- great memories of that area. picked wild strawberries near the summit, wild blueberries around the base. spirit lake had been created, IIRC, by a previous eruption or landslide that dammed off one end of a valley instantaneously- submerging full grown trees below the surface that were still visible (and creepy af). we had to row across the lake to get the camp spot and it freaked the hell out of me as a little kid. still irrationally terrified of submerged objects.
Not sure if you noticed before, but I believe you can see, right above the gentleman in yellow in the photo, you can observe the beginnings of one of the volcanic bulges forming on the mountain, just above the tree tops.added the picture.
Ape Caves is the side of the mountain where I worked. I led tours down there with the old lanterns. Also worked up at Windy Ridge. That was a fun road to drive a few times a week.We visited the MSH visitor's center park around 2000. It's about 30 miles away from the mountain but on clear days the views are unbelievable. They show a really cool movie with all the events leading up to the big blow and then the screen rises up, the curtains open and there's the actual mountain right in front of you!
We did some great hikes on the pristine side of the mountain including the Ape Caves which are lava tubes that weave underground. You go down a ladder in a maw in the earth armed with an old lantern and then walk through these tunnels. Never forget it.
I can't remember the name of the motel we stayed at but I'm pretty sure it was in Longview. It was like a salmon fisherman mom and pop. The river was across the street. There were paper towel rolls outside the front door mounted on the wall. I guess for fish cleaning? We laugh about that place now, the carpet was disgusting and it was a definite budget stop.Ape Caves is the side of the mountain where I worked. I led tours down there with the old lanterns.
