Hi guys, what's going on in this thread?
 
2013-10-21 03:24:52 PM  
I remember walking out on my front porch one fine day in 1981, and seeing a tiny little mushroom cloud on the horizon.

It was pretty cool, actually.  Especially since all that ash blew east, and not north.
 
2013-10-21 03:29:58 PM  
I lived 200+ miles to the north and we heard the boom.  We thought people were blowing up stumps behind our house.  (it was 1980)
 
2013-10-21 03:32:31 PM  
I didn't see the original May 18th eruption.   I lived about 70 miles north, and saw one of the follow on eruptions.  From my vantage, the ash cloud was about an inch high.

I believe there is a fairly recent PBS Nova video out their website on this as well. They even have a time lapse video showing absolutely massive rock formations slowing emerging from the caldera over weeks and months only to crumble and fall once they get too high.

It sounds like Nature's winning.  Her docile spree has set her free.

Was horseback riding on a ridge in St. Helens Oregon when she went off.  Horse noticed it before I did.  Went to many a eruption party by the Columbia River during that time.

Nature can regrow after a volcanic explosion.  Fixin' clear cut aint no thang to Nature.

True, and honestly it is pretty interesting to see all of the experimental plots weyerhauser has set up to see under which circumstances trees grow back the fastest.  They get a higher profit off of regrowth than old growth, so it's to their benefit to replant clear cut in the most efficient way possible

Didn't a volcano erupt in Alaska soon after he made his ignorant speech?
 
2013-10-21 04:53:14 PM  
I remember watching people sweep and shovel ash off their cars and sidewalks on the news as a kid.

Mt. Redoubt.

As for the St. Helens eruption, I was too far away to experience it directly but I certainly remember seeing it (and the affected towns nearby) on the news. Some people were selling little souvenir bottles of the ash to tourists, while other people were clearing the stuff off their car with a snow shovel.

OTOH, the timber industry did significant replanting on forestry lands impacted by the eruption.  While it has taken decades for land within the federal monument areas to recover, the areas outside rebounded much faster.

Having said that, the forestry lands are mostly a monoculture.  The monument lands have been going through stages of wildflower and grass fields, first growth shrubs and trees.  Slower, but more impressive.

They sold that shiat for decades.  You couldn't walk into a gift shop without finding a little keychain with some ash in it, or a figurine or other kitsch made out of ash.   It spawned a whole economy!

logging is tightly regulated when it comes to "old growth" in the states (nevermind that there are examples of "old growth" in local parks that have been logged at least twice since settlers have been here. it does in fact come back)

& there is waaaaay higher profit (per foot) in trading "old growth"  (clear fiber)  vs.  commons / studs / fencing.   it's just the volume consumed is at different ends of the spectrum.  mills want to sell the whole wood pile. that's what they are there for & they are very resourceful in coming up with every way to skin a cat.

Not really, as explained above timber harvest can be very beneficial.  Decades of research has shown us how to mimic natural disturbance through harvesting techniques and equipment.  You think fire suppression has been a good thing for natural landscapes?  Especially landscapes that are predominantly pine?  There are many forest types that used to burn on a very short rotation, but man has changed that for safety purposes.

One of my professors in Forestry school went to UofW and was a grad student when the eruption happened.  He visited the area quite regularly afterwards and also owned his own plane, so he had several years worth of personal photographs that showed the recovery quite well.

Yeah, right over our small farm.  We had to bring the horses into the house with us to keep them from choking.  (in case anyone ever asks...horses can really mess up a house)

My mom had to run and rescue my little sister from a 4H rabbit show.  The 65 Fairlane she had at the time had ash completely packed in the air cleaner when we checked it several days later.
 
2013-10-21 05:31:52 PM  
I was nine and living in Spokane when she blew. Watching darkness slowly encroach during mid day was surreal. Shut down the town for about a week while they cleared streets. Of course I had to shovel the crap of out sidewalks and driveway. Me and my friends would build up big piles of ash and ride our Big Wheels through it. I still have a couple of jars of ash at my mom's place.

I visited the mountain in 88 and it was still ash as far as the eye could see. Now, the trees and plants reclaiming their turf. It's amazing to see.

My hometown of Crackima is the city you see from all of the "disaster" photos of St. Helens.  We could see lightning bolts in the ash clouds and it was darker than night at 9am.

Yeah, in my experience horses are basically crap factories that are good at running.  They're also walking crap factories that are a lot of fun to ride.

CrazyCracka420: So grass and vegetation is growing where it was wiped out?  Is the obvious tag on vacation?  Am I missing something?


I think the bigger story is how long it took for vegetation to grow back.  Things grow pretty fast up here, but the areas closest to the mountain are still completely bare 33 years later.

I lived in Crackima (Selah actually) for a while.  When St. Helens blew, though, I lived in Ridgefield, WA, and was a month from being born.  My dad still owns the house in Selah, and two years ago we went and tore off the old cedar shake roof.  There was about an inch and a half of evenly distributed St. Helens ash under the shakes.

We went there in July and noticed one species looked like a low-res Medal Of Honor forest.  The vast acres of one type of tree that grew all its branches in uniform layers was really weird.

As I'm typing this I'm holding a little plastic box of souvenir ash.

I know exactly what you are talking about. Those are Noble Fir if I remember correctly. It looks very uncanny.

I was there in 2006 and innocently asked the ranger if this was a desert area since there seemed to so very little vegetation on the north slope.  He said they got several feet of rain annually.

/sterilizing the soil means years of little or no vegetation

I remember when that happened. I was on the ferry headed to Seattle. The captain announce that St. Helens had erupted. Everyone on the boat went over to look. It caused the ferry to list to that side. Very cool to see.

/props to the USGS for the warnings. Very few people died as a direct result of the eruption.

Weyerhaeuser and Dixie Lee got SOOO lucky it went in a Sunday. A day later and logging crews would have been killed left and right.

2013-10-22 12:12:16 AM  
We lived in Kent and my family moved to California 3 weeks before the eruption.

OneDeltaTenTango:

Yes and no. The USGS did a great job of anticipating the eruption, and that did clear out the campers. But no one seemed to grasp the danger of the upcoming eruption, or anticipate the lateral component to it, so there were really lots of people in in the area in the days leading up to it. If people had things to do in the area, they were there. The fact is that if it hadn't been on a Sunday, there would be a few hundred loggers fertilizing the new growth.

/One of my mom's close friends, a newspaper photographer, was one of the casualties.
 
2013-10-22 12:36:30 AM  
I lived in Victoria, BC and remember hearing the blast and seeing the footage on the news. Seeing the blast zone and regrowth in 2000 was very cool and a surprisingly emotional experience.

They're also pretty big. I was surprised how high up I was and when they start to gallop ... wow! I was more nervous than the first time I was in a Cessna 172 for a "pilot for a day" thingy.
 
2013-10-22 01:40:16 AM  
I was three months old and living in BC.  I don't remember a goddamn thing.
 
2013-10-22 03:21:49 AM  
My Grandmother said she got a very fine layer of ash all the way over in Minnesota.
 
2013-10-22 03:58:50 AM  
I was 4, living in Rochester, NY when St. Helens blew...I had no idea.  A year later we moved to Longview, Wa.  Many moons later, I've asked my parents why in the world would they possibly move to the one place in the continental United States with an active volcano!  I've still not received a decent answer.

For years after May 18, 1980 the mountain would rumble and burp from time to time...I always thought that it seemed to do so on its anniversary...and we could see it.

I remember the first time we went up to see the mountain...Windy Ridge was very popular.  Lots of cars and RVs coming up and down the mountain.  The problem was that they only had a single lane logging road hugging the side of a cliff and no guard rails for those RVs coming down.  The road was so bad, it bounced the exhaust off our car and Dad had to use his belt to tack it back on for the trip home.

Most of my extended family are still in New York, and whenever they'd come to visit, we take them up to Windy Ridge (or the newer Johnston Ridge Observatory)...as such, we've had a chance to see the place come back to life first hand.  Fortunately, they've improved the road...
