Quoted: This is a Google Street View image, wide angle lens makes it look really damn small - but it's a decent size hill. Didn't used to be covered in green stuff. That whole thing is a pile of dredged ash, sitting right next to I-5 where it crosses the north fork of the Toutle River. It was a bit taller back when I was a kid, and nothing was growing on it yet - the big grey pile of ash was a very distinctive landmark as you drove along I-5. The views before things started to grow again were amazing and damned creepy. Another trip as a kid, my dad drove us up to Mt St Helens and we were driving around on the forest service roads. One of them went right through the debris flow area - nothing bigger than small saplings and shrubs at the time, and not many of them - all rock as far as the eye could see, looking up a chute straight into the gaping side of the mountain. Really makes you feel small. http://www.kd7bcy.com/images/arfcom/ashpile.jpg View Quote The Toutle River water is still white with ash being carried downstream from the eruption zone. It's not as pronounced as it used to be, but it's still white. Some years back it looked like a river of milk. If you are ever in the region...take a day and drive up to Johnston Ridge Observatory. It's too awe inspiring to describe. Just the scope of the devastation is unfathomable. The introspection on your insignificance is life changing. |

My sister lives about 20 miles from St. Helens. It's an eerie place to visit--even 35 years later.

My family has a mason jar of it. A lot of it is in mason jars, hour glasses, and other containers distributed throughout the US as souvenirs. View Quote I was a kid in Milwaukee when it happened. I remember after a week or two, the news was full of pleas from the USPS not to mail envelopes of the ash because it was gumming up the mail sorting machines everywhere... |

Scientist said it would take at least a decade or so for the magma pressure within the caldera to build up to a point where an eruption would happen. So people around Yellowstone shouldn't have any worries.

Just because the Yellowstone caldera is big doesn't mean that the eruption will be the end of the world. You never know with volcanic shit. It MIGHT kill us all, or it might just act like Hawaii...constant low energy gushing eruption for decades.

Keith Ronnholm is my dad's cousin. He took a bunch of the time elapsed photos that everyone see's. Its neat seeing him on tv once a year during the anniversary of the eruption. My parents have some photos from the original negatives floating somewhere around their house. My parents visited him about 10 years ago and he took them all around the mountain.

I had just started work at the Richland Police Dept. May 17th was my first night on graveyard and I got off shift at 6am. I went home and changed the handlines for 5 acres then hit the bed.
It wasn't long before my Mother was screaming for me that the mountain had blown. I grabbed my camera and got some pictures of the sky. I had never seen clouds like that before or since. They were like dirt (didn't think at the time they were filled with ash) and in the shape of giant puffs of cotton. With in minutes the ash started falling on us. We got around 6 inches or so of it in the Canyon and not so much in town. I would say it was like in the films of the Dust Bowl as when you drove anyplace there was a big ash cloud behind you. You had to replace your air filter constantly. At the time I had a 78 full size Blazer. One day that summer I took the top off and drove it to work. That night we got a teletype that St. Helens had blown an ash cloud over 20,000 ft up and it was headed our way. It covered us pretty good, leaving behind about an inch of ash. In the morning I went out to my Blazer and thats when I remembered that I had taken the top off. Shit. The inside was covered. It took 20 minutes of cleaning just to see the dash and clear the seat. When I got home I put the top back one. A couple of weeks later my younger Brother and I went to Vancouver to see some friends. While we were there St. Helens spit out some more ash and it was a big one. We had to buy a new air filter and decided to buy two. Thankfully we did as half way home the new one clogged up. I'll see if I can find the cloud pics and post them. Ed |

What caught everyone off guard was that the mountain blew sideways first and not straight up. So while people several miles away from the north side of the mountain died, people actually working on the south side of the mountain survived.

Hawaiian volcanoes expel very low viscosity, low gas content basalt lavas while those underlying Yellowstone are high viscosity, high gas content types. The longer the caldera charge cycle takes, the more gas (pressure) buildup can occur. When the magma is finally vented to the surface it'll explosively decompress and produce Plinian-style eruptions.

IIRC, it was recently discovered why ancient Roman concrete was so durable--as in centuries, as opposed to modern concrete's decades.
The Romans included lots of volcanic ash in the mix. http://www.bloomberg.com/bw/articles/2013-06-14/ancient-roman-concrete-is-about-to-revolutionize-modern-architecture Sounds to me like an opportunity. We should be mining all that FREE construction material, and making roads, bridges, and buildings that will last for centuries. It's an ill wind that blows no good. |
