Would not be an ideal place if it erupts. Are the trails still open?

Geologists have discovered a second magma chamber beneath volcano They believe this feeds the smaller chamber directly below the mountain Earthquakes in the area may be a sign of magma pumping between them Geologists still consider Mount St Helens to be of high risk of erupting
Its scarred and jagged crater is a reminder of the terrible devastation that Mount St Helens wrought over the Washington countryside 35 years ago.
Now a new study of the volcanic plumbing lurking beneath the 8,363ft (2,459 metre) summit suggests the volcano could yet again blow its top in an explosive eruption.
Geologists studying the volcano, which is responsible for the most deadly eruption in US history, have discovered a second enormous magma chamber buried far beneath the surface.
This giant pool of molten rock, which lies between seven to 25 miles (40km) below the surface, is connected to a slightly smaller chamber that lies directly beneath the mountain.

I remember when the eruption happened. The Oregonian had an article that week, quoting a geologist, who said, “We’ve just seen 10,000 years of geological activity in one day.”
“...suggests the volcano could yet again blow its top in an explosive eruption.”
I imagine that their is a 98% chance that it will blow - someday.
And that sequence of photos - it is amazing. There was a married couple flying over the mountain that day as well and they got some amazing photos. The pilot put the plane in a steep dive to build up enough speed to get around to the opposite side before they got blown out of the sky.
Not even close. Yellowstone is over a hot spot, Helen is a subduction zone generated volcano ( and you know, Subduction leads to Orogeny!)...
We could build a couple of walls. Southern and northern !
Like a big zit that got popped.

Don't you mean "Stuck In the Middle With You."
I hike in that area a lot. I haven’t hiked the blast zone. It’s nice because the massive quantity of people from King County (Seattle) don’t like to go that far South for a day-hike.
Make wall sections out of it and ship them to the southern border.
Fascinating terrain. Certainly presents a challenge.
An unexpected massive landslide (the biggest ever recorded) immediately preceding the eruption allowed for the outward explosion. Some suspect the same instability exists in Mt Rainer. Hard to predict these things.
Forgive me, for I am but a lowly 'murican. I can't think with metric measurements. Is that like a mile or so?
Too funny! I lived in nearby Vancouver in 1980. Yes, I’d love to see parts of Portland cleansed by mother nature.
Forgiven, but “science” uses meters, kilometers, etc for insane reasons.
1.24274238 miles or thereabouts according to the calculator thingy.
4 km down, or 2.48548477 miles, there is another stopping point for the volcanic fluids.
Personally, I’d like to see a 3D representation of the time depth plot.
Worst....Portlandia....Episode....EVER!
Most of the top is gone, so it would not be as bad.
I saw one hell of a big mountain lion on Mt St Helens in 2008. Scared the crap out of me.
Yeah he was a hoot.
Not really sad when he died. I thought he was kind of stupid at the time. We talked about him in our Geology class.
Our professor, who was not a lib PC type, pretty much said, “This guy is going to get covered in thousand degree ash. He will cease to exist in part of a second.”
LOL
Is at here any way we can tax Oregon for all of this climate upset? After all, it is located in their State?
I know, I know - the feds own the mountain, but they're bankrupt and are just printing worthless money these days...
You were fortunate to be outside of Portlandia...I was stuck in CrazyTown for a while but fled back to Corvallis.
